### <a name="com.microsoft.Attention"></a><a name="com.microsoft.attention">**com.microsoft.Attention**</a>

  Multi-Head Attention that can be either unidirectional (like GPT-2) or bidirectional (like BERT).
  
  The weights for input projection of Q, K and V are merged. The data is stacked on the second dimension. Its shape
  is (input_hidden_size, hidden_size + hidden_size + v_hidden_size). Here hidden_size is the hidden dimension of Q and K,
  and v_hidden_size is that of V.
  
  The mask_index is optional. Besides raw attention mask with shape (batch_size, total_sequence_length)
  or (batch_size, sequence_length, total_sequence_length) with value 0 for masked and 1 otherwise,
  we support other two formats: When input has right-side padding, mask_index is one dimension with shape (batch_size),
  where value is actual sequence length excluding padding. When input has left-side padding, mask_index has
  shape (2 * batch_size), where the values are the exclusive end positions followed by the inclusive start positions.
  
  When unidirectional is 1, each token only attends to previous tokens.
  
  Both past and present state are optional. They shall be used together, and not allowed to use only one of them.
  The qkv_hidden_sizes is required only when K and V have different hidden sizes.
  
  When there is past state, hidden dimension for Q, K and V shall be the same.
  
  The total_sequence_length is past_sequence_length + kv_sequence_length. Here kv_sequence_length is the length of K or V.
  For self attention, kv_sequence_length equals to sequence_length (sequence length of Q).
  For cross attention, query and key might have different lengths.

### <a name="com.microsoft.BitmaskDropout"></a><a name="com.microsoft.bitmaskdropout">**com.microsoft.BitmaskDropout**</a>

  BitmaskDropout takes an input floating-point tensor, an optional input ratio (floating-point scalar) and an optional input training_mode (boolean scalar).
  It produces two tensor outputs: output (floating-point tensor) and mask (optional `Tensor<uint32>`). If `training_mode` is true then the output Y will be a random dropout.
  Note that this Dropout scales the masked input data by the following equation, so to convert the trained model into inference mode, the user can simply not pass `training_mode` input or set it to false.
  ```
  output = scale * data * mask,
  ```
  where
  ```
  scale = 1. / (1. - ratio).
  ```
  
  This op functions in much the same was as Dropout-11 and Dropout-13 do, except that the mask is output as a bit-packed uint32 tensor, instead of a boolean tensor.

### <a name="com.microsoft.CausalConvWithState"></a><a name="com.microsoft.causalconvwithstate">**com.microsoft.CausalConvWithState**</a>

  Stateful causal depthwise convolution, generalized to N spatial dimensions.
  
  Used by Gated DeltaNet (Qwen3.5) and Mamba (Jamba, FalconMamba) as a preprocessing step.
  Replaces the 3-op pattern (Concat + Conv + Slice) with a single fused operation.
  
  The convolution is causal (looks only at current and past positions along the last
  spatial dimension) and depthwise (each channel is convolved independently with its own kernel).
  
  Input layout is channels-first: (batch_size, channels, ...).
  Weight layout: (channels, 1, k_1, ...) for depthwise convolution.
  The carry state stores the last (k-1) positions along the causal axis for incremental decode.
  
  The ndim attribute generalizes the op to 1D, 2D, or 3D spatial dimensions. Causality is
  enforced on the last spatial dimension only.
  
  The optional activation attribute supports fused SiLU/Swish activation.

### <a name="com.microsoft.CropAndResize"></a><a name="com.microsoft.cropandresize">**com.microsoft.CropAndResize**</a>

  Extracts crops from the input image tensor and resizes them using bilinear sampling or nearest neighbor sampling
          (possibly with aspect ratio change) to a common output size specified by crop_height and crop_width.
          Returns a tensor with crops from the input image at positions defined at the bounding box locations in boxes.
          The cropped boxes are all resized (with bilinear or nearest neighbor interpolation) to
          a fixed size = [crop_height, crop_width]. The result is a 4-D tensor [num_boxes, crop_height, crop_width, depth].
          The resizing is corner aligned.

### <a name="com.microsoft.DecoderMaskedSelfAttention"></a><a name="com.microsoft.decodermaskedselfattention">**com.microsoft.DecoderMaskedSelfAttention**</a>

  Self attention that supports input sequence length of 1.
  
  The weights for input projection of Q, K and V are merged. The data is stacked on the second dimension. Its shape
  is (input_hidden_size, hidden_size + hidden_size + v_hidden_size). Here hidden_size is the hidden dimension of Q and K,
  and v_hidden_size is that of V.
  
  The mask_index is optional. If it is provided, only raw attention mask with shape (batch_size, total_sequence_length) is supported currently.
  
  Both past and present state need to be provided.
  
  The qkv_hidden_sizes is required only when K and V have different hidden sizes.
  
  The total_sequence_length is past_sequence_length + kv_sequence_length. Here kv_sequence_length is the length of K or V.
  Currently, only self attention is supported which means that kv_sequence_length equals to sequence_length (sequence length of Q).

### <a name="com.microsoft.GatherBlockQuantized"></a><a name="com.microsoft.gatherblockquantized">**com.microsoft.GatherBlockQuantized**</a>

  GatherBlockQuantized is a Gather with data quantized. It is similar to Gather (https://github.com/onnx/onnx/blob/main/docs/Operators.md#gather) with differences:
    1. Input `data` is a constant. It is quantized block-wise along attribute `quantize_axis` with block size specified by attribute `block_size`.
       `block_size` must be a power of 2 and not smaller than 16, like 16, 32, 64, 128, ...
    2. Input `data`'s scale and zero point are specified by input `scales` and `zero_points`. `scales` and `zero_points` are also constants.
       If `zero_points` is not provided, the default value is 0 for int4/uint4, or 2^(bits-1) for uint8.
    3. During the op execution, `data` and `indices` are first used to generate the quantized output. Then, `scales` and `zero_points` are used
       to dequantize the output.
    4. The `output` and `scales` have the same type. The `data` and `zero_points` have the same type.
    5. For uint8 data, the `gather_axis` must be 0. The supported `bits` values for uint8 data are 2, 4, and 8;
       for `bits` < 8 the values are packed along the last dimension (low-order bits first).

### <a name="com.microsoft.GridSample"></a><a name="com.microsoft.gridsample">**com.microsoft.GridSample**</a>

  Given an `input` and a flow-field `grid`, computes the `output` using `input` values and pixel locations from `grid`.
        Currently, only spatial (4-D) inputs are supported. For `input` with shape (N, C, H, W) and `grid` with shape (N, H_out, W_out, 2),
        the `output` will have shape (N, C, H_out, W_out).
        For each output location `output[n, :, h, w]`, the size-2 vector `grid[n, h, w]` specifies `input` pixel locations `x` and `y`,
        which are used to interpolate the output value `output[n, :, h, w]`.
        The GridSample operator is often used in doing grid generator and sampler in the [Spatial Transformer Networks](https://arxiv.org/abs/1506.02025).
        See also in [torch.nn.functional.grid_sample](https://pytorch.org/docs/master/generated/torch.nn.functional.grid_sample.html#torch-nn-functional-grid-sample).

  Applies Group Normalization over a mini-batch of inputs as described in the paper Group Normalization (https://arxiv.org/abs/1803.08494).
  
  This operator transforms input according to
    y = gamma * (x - mean) / sqrt(variance + epsilon) + beta
  
  The input channels are separated into num_groups groups, each containing num_channels / num_groups channels. num_channels must be divisible by num_groups. The mean and standard-deviation are calculated separately over the each group.
  The weight and bias are per-channel affine transform parameter vectors of size num_channels.
  
  The activation attribute can be used to enable activation after group normalization.

### <a name="com.microsoft.GroupQueryAttention"></a><a name="com.microsoft.groupqueryattention">**com.microsoft.GroupQueryAttention**</a>

  Group Query Self/Cross Attention with KV Cache Quantization Support.
  
  This operator implements causal grouped-query attention with past state (KV cache) support.
  It also supports optional float8, int8 or int4 quantization for the KV cache to reduce memory footprint.
  
  **Cache Format:**
  The past and present KV cache tensors are expected in a BNSH format: `(batch_size, num_heads, cache_sequence_length, head_size)`, where `cache_sequence_length` is the length of the cached key/value sequences, or the maximum sequence length when past and present buffer sharing is used.
  
  **Quantization:**
  When quantization is enabled, `past_key` and `past_value` inputs can be of type `float8e4m3fn`, `uint8` or `int8`. The corresponding `k_scale` and `v_scale` tensors must be provided.
  The operator will output `present_key` and `present_value` in same format as the `past_key` and `past_value`.
  
  For 4-bit quantization, the data type is uint8 where each byte contains two 4-bit values. The bit width of quantized KV cache can be set using `kv_cache_bit_width` attribute.
  
  The shapes of the k_scale, v_scale tensors shall be broadcastable to present_key shape.
  
  **Quantization Modes (`k_quant_type`, `v_quant_type` attributes):**
  - **"NONE"**: No quantization.
  - **"PER_TENSOR"**: A single scale for the entire tensor. Scale example shape: `[1]`.
  - **"PER_CHANNEL"**: A scale for each channel. Scale example shape: `[1, num_heads_k, 1, head_size]`.

### <a name="com.microsoft.LinearAttention"></a><a name="com.microsoft.linearattention">**com.microsoft.LinearAttention**</a>

  Unified linear attention operator for autoregressive decoding (T=1) and prefill (T>1).
  
  All inputs use 3D packed format [B, T, H*D]; q_num_heads and kv_num_heads are always
  required. The op internally unpacks to 4D for computation.
  
  The update_rule attribute selects the recurrence type:
  - "linear": S_t = S_{t-1} + k_t ⊗ v_t; o_t = scale * q_t^T S_t
  - "gated": S_t = exp(g_t) * S_{t-1} + k_t ⊗ v_t; o_t = scale * q_t^T S_t
  - "delta": S_t = S_{t-1} + β_t * k_t ⊗ (v_t - S_{t-1}^T k_t); o_t = scale * q_t^T S_t
  - "gated_delta": S_t = exp(g_t) * S_{t-1} + β_t * k_t ⊗ (v_t - exp(g_t) * S_{t-1}^T k_t); o_t = scale * q_t^T S_t
  
  where g_t is the decay (in log-space), β_t is the update rate, and ⊗ denotes outer product.
  
  Semantics: Equivalent to running the recurrent update sequentially for each token,
  but may be implemented using chunk-parallel algorithms for GPU efficiency.

  attends to its W previous tokens and W succeeding tokens with W being the window length. A selected few tokens
  attend globally to all other tokens.
  
  The attention mask is of shape (batch_size, sequence_length), where sequence_length is a multiple of 2W after padding.
  Mask value < 0 (like -10000.0) means the token is masked, 0 otherwise.
  
  Global attention flags have value 1 for the tokens attend globally and 0 otherwise.

### <a name="com.microsoft.MatMulBnb4"></a><a name="com.microsoft.matmulbnb4">**com.microsoft.MatMulBnb4**</a>

  MatMulBnb4 is a MatMul with weight quantized with 4 bits using either FP4 or NF4 data type (https://arxiv.org/pdf/2305.14314.pdf). It does Matrix Multiplication like MatMul (https://github.com/onnx/onnx/blob/main/docs/Operators.md#matmul) with differences:
    1. Input B is a 2D constant Matrix. Its input feature count and output feature count are specified by attribute 'K' and 'N'.
    2. Input B is quantized with 4 bits with quantization data type specified by attribute 'quant_type'. It is transposed, flattened and quantized blockwisely with block size specified by attribute 'block_size'.
       And block_size is not an arbitrary number and must be a power of 2 and not smaller than 16, like 16, 32, 64, 128,..
    3. Input B's quantization constants or scales are specified by input 'absmax'.
  
    Input B is stored as uint8_t with shape: [(N * K + 1) / 2].
    Input absmax is stored in same type as original type of B(float32, float16) with shape like: [(N * K + block_size - 1) / block_size].
  
  
    1. (Default value) transB=True (Majorly used for forward pass)
      Shape of A: [D0, D1, ..., Dn, K]
      Shape of Dequanted B: [N, K], this is aligned with how PyTorch defined the linear weight, .e.g [out_features, in_features].
  
      The computation math:
        dequant_B = dequant(B, absmax, quant_type, block_size)
        transposed_dequant_B = dequant_B^T
        output = A @ transposed_dequant_B
  
      Shape of output: [D0, D1, ..., Dn, N]
  
    2. transB=False (Majorly used for backward pass)
      Shape of A: [D0, D1, ..., Dn, N]
      Shape of Dequanted B: [N, K], this is aligned with how PyTorch defined the linear weight, .e.g [out_features, in_features].
  
      The computation math:
        dequant_B = dequant(B, absmax, quant_type, block_size)
        output = A @ dequant_B
  
      Shape of output: [D0, D1, ..., Dn, K]

  Matrix product with right hand matrix being pre-packed and quantized int4 data blob.
  During quantization, the matrix is divided into blocks, where each block is a
  contiguous subset inside each column. Each block is quantized into a
  sequence of 4b integers with a scaling factor and an optional offset.
  Currently 3 quantization types are supported:
  (0): block size 32, no offset, (1): block size 32, with offset, (2): block size 64,
  no offset

### <a name="com.microsoft.MatMulNBits"></a><a name="com.microsoft.matmulnbits">**com.microsoft.MatMulNBits**</a>

  MatMulNBits performs a matrix multiplication where the right-hand-side matrix (weights) is quantized to N bits.
  
  It is a fusion of two operations:
  1. Linear dequantization of the quantized weights using scale and (optionally) zero-point with formula:
     dequantized_weight = (quantized_weight - zero_point) * scale
  2. Matrix multiplication between the input matrix A and the dequantized weight matrix.
  
  The weight matrix is a 2D constant matrix with the input feature count and output feature count specified by attributes 'K' and 'N'.
  It is quantized block-wise along the K dimension with a block size specified by the 'block_size' attribute.
  The block size must be a power of 2 and not smaller than 16 (e.g., 16, 32, 64, 128). Each block has its own scale and zero-point.
  The quantization is performed using a bit-width specified by the 'bits' attribute, which can take values from 2 to 8.
  
  The quantized weights are stored in a bit-packed format along the K dimension, with each block being represented by a blob of uint8.
  For example, for 4 bits, the first 4 bits are stored in the lower 4 bits of a byte, and the second 4 bits are stored in the higher 4 bits of a byte.

### <a name="com.microsoft.MatMulNBitsMlp"></a><a name="com.microsoft.matmulnbitsmlp">**com.microsoft.MatMulNBitsMlp**</a>

  MatMulNBitsMlp fuses two MatMulNBits projections that share the same input and computes
  
      gate = MatMulNBits(A, gate_weight) + gate_bias
      up = MatMulNBits(A, up_weight) + up_bias
      Y = activation(gate) * up
  
  It can also optionally fuse SimplifiedLayerNormalization or SkipSimplifiedLayerNormalization before the
  two projections:
  
    A_norm = SimplifiedLayerNormalization(A, norm_scale, epsilon)
      gate = MatMulNBits(A_norm, gate_weight) + gate_bias
      up = MatMulNBits(A_norm, up_weight) + up_bias
      Y = activation(gate) * up
  
    A_norm = SkipSimplifiedLayerNormalization(A, skip, norm_scale, epsilon)
      gate = MatMulNBits(A_norm, gate_weight) + gate_bias
      up = MatMulNBits(A_norm, up_weight) + up_bias
      Y = activation(gate) * up
  
  This operator is intended for decoder MLP patterns such as Qwen-style gate and up projections, but it remains
  semantically valid for both prefill and decode because the output shape is the standard MatMul result shape
  derived from the runtime shape of A and the shared attributes K and N.
  
  The operator contract includes a string attribute describing the fused gate activation.
  
  When fused from SkipSimplifiedLayerNormalization, the optional residual-sum output may also be materialized:
  
    A_norm, input_skip_bias_sum = SkipSimplifiedLayerNormalization(A, skip, norm_scale, epsilon)
    gate = MatMulNBits(A_norm, gate_weight) + gate_bias
    up = MatMulNBits(A_norm, up_weight) + up_bias
    Y = activation(gate) * up

### <a name="com.microsoft.MatMulNBitsQkv"></a><a name="com.microsoft.matmulnbitsqkv">**com.microsoft.MatMulNBitsQkv**</a>

  MatMulNBitsQkv fuses either SimplifiedLayerNormalization (RMSNorm)
  or SkipSimplifiedLayerNormalization with three MatMulNBits projections that share the
  same normalized activation.
  
    A_norm = SimplifiedLayerNormalization(A, norm_scale, epsilon)
    Q = MatMulNBits(A_norm, q_weight) + q_bias
    K = MatMulNBits(A_norm, k_weight) + k_bias
    V = MatMulNBits(A_norm, v_weight) + v_bias
  
  If skip is provided, the operator computes the SkipSimplifiedLayerNormalization variant
  and may also return the input+skip residual sum as output 3.
  
  This operator is intended as a decode-oriented QKV fusion primitive.

        usually uses top 32 experts and Mixtral(https://huggingface.co/blog/mixtral).
  
        The SwiGLU (Swish-Gated Linear Unit) activation function is like:
           g = xW + b
           l = xV + c
           G = clamp(g, max=limit)
           L = clamp(l, min=-limit, max=limit)
           swiglu = G * sigmoid(alpha * G) * (L + beta)
        where x is the input, W and V are weight matrices, b and c are bias vectors, and alpha, beta and limit are constant float parameters.
        When swiglu_fusion=0, two GEMMs are not fused, and they are FC1 and FC3 in the inputs.
        When swiglu_fusion=1, two GEMMs are fused so that g and l are computed in a single GEMM (FC1), and g and l are interleaved on each row of size 2 * inter_size.
        When swiglu_fusion=2, two GEMMs are fused, and g and l are concatenated on each row.

Otherwise the size is (N x C x D1 x D2 ... x Dn).

  This is the packed version of Attention.
  
  Sequences in one batch usually don't have same length and they are padded to have same length,
  e.g., below is a batch with 3 sequences and tokens* are padded.
    Sequence_0:   0,  1*, 2*,  3*
    Sequence_1:   4,  5,  6*,  7*
    Sequence_2:   8,  9,  10,  11
  
  PackedAttention is designed to takes in packed input, i.e., only the real tokens without padding.
  An input as above will be packed into 3 tensors like below:
   - input ([h0, h4, h5, h8, h9, h10, h11])
   - token_offset: 0, 4, 5, 8, 9, 10, 11,  1*, 2*, 3*, 6*, 7*
   - cumulated_token_count: 0, 1, 1+2, 1+2+4
  
  Input tensors contains the hidden embedding of real tokens.
  Token_offset records the offset of token in the unpacked input.
  cumulated_token_count records cumulated length of each sequence length.
  
  The operator only supports BERT like model with padding on right now.

### <a name="com.microsoft.PagedAttention"></a><a name="com.microsoft.pagedattention">**com.microsoft.PagedAttention**</a>

  Paged Attention.
  
  This op leverages a block-based KV cache to enable continuous batching for LLMs. Currently, it is designed to work with
  the CUDA Execution Provider only.
  
  In other attention ops, batch entries typically aren't of the same length, so they are padded.
  Below is a batch with 3 sequences where * denotes a padding token.
    Sequence_0:   0,  1*, 2*,  3*
    Sequence_1:   4,  5,  6*,  7*
    Sequence_2:   8,  9,  10,  11
  
  PagedAttention is designed to take in packed input, i.e., only the real tokens without padding.
  For example, the input shown above will be packed into 3 tensors like below:
   - query ([q0, q4, q5, q8, q9, q10, q11])
   - key ([k0, k4, k5, k8, k9, k10, k11])
   - value ([v0, v4, v5, v8, v9, v10, v11])
   - cumulative_sequence_length: 0, 1, 1+2, 1+2+4
  This packing omits padding tokens.
  
  The query, key and value tensors contain result of hidden embedding of real tokens after input projections.
  cumulative_sequence_length records cumulated length of each sequence length.

### <a name="com.microsoft.QLinearAveragePool"></a><a name="com.microsoft.qlinearaveragepool">**com.microsoft.QLinearAveragePool**</a>

  QLinearAveragePool consumes an input tensor X and applies average pooling across
   the tensor according to kernel sizes, stride sizes, and pad lengths.
   average pooling consisting of computing the average on all values of a
   subset of the input tensor according to the kernel size and downsampling the
   data into the output tensor Y for further processing. The output spatial shape will be following:
   ```
   output_spatial_shape[i] = floor((input_spatial_shape[i] + pad_shape[i] - kernel_spatial_shape[i]) / strides_spatial_shape[i] + 1)
   ```
   or
   ```
   output_spatial_shape[i] = ceil((input_spatial_shape[i] + pad_shape[i] - kernel_spatial_shape[i]) / strides_spatial_shape[i] + 1)
   ```
   if ceil_mode is enabled
  
   ```
   * pad_shape[i] is sum of pads along axis i
   ```
  
   `auto_pad` is a DEPRECATED attribute. If you are using them currently, the output spatial shape will be following:
   ```
   VALID: output_spatial_shape[i] = ceil((input_spatial_shape[i] - kernel_spatial_shape[i] + 1) / strides_spatial_shape[i])
   SAME_UPPER or SAME_LOWER: output_spatial_shape[i] = ceil(input_spatial_shape[i] / strides_spatial_shape[i])
   ```
   And pad shape will be following if `SAME_UPPER` or `SAME_LOWER`:
   ```
   pad_shape[i] = (output_spatial_shape[i] - 1) * strides_spatial_shape[i] + kernel_spatial_shape[i] - input_spatial_shape[i]
   ```
  
  The output of each pooling window is divided by the number of elements (exclude pad when attribute count_include_pad is zero).
  
  Input and output scales and zero points are used to convert the output to a new quantization range.
  Output = Dequantize(Input) -> AveragePool on fp32 data -> Quantize(output)

  Computes the mean of the low-precision input tensor's element along the provided axes.
  The resulting tensor has the same rank as the input if keepdims equal 1. If keepdims equal 0,
  then the resulting tensor have the reduced dimension pruned. The above behavior is similar to numpy,
  with the exception that numpy default keepdims to False instead of True.
  Input and Output scales and zero points are used to requantize the output in a new range.
  This helps to improve accuracy as after ReduceMean operation the range of the output is expected to decrease.

### <a name="com.microsoft.QMoE"></a><a name="com.microsoft.qmoe">**com.microsoft.QMoE**</a>

  Quantized mixture of experts (MoE).
  
        The quantized weights are stored in column major order per expert.
        The quantization block size can be specified. If not provided, column wise quantization is used.
  
        The formula of linear dequantization of the quantized weights using scale and (optionally) zero-point is:
          dequantized_weight = (quantized_weight - zero_point) * scale
        When zero_point is not provided, the default value is 2^(bits-1): 2 for 2 bits, 8 for 4 bits, 128 for 8 bits.
  
        If block_size is provided, both hidden_size and inter_size must be divisible by the block size, and
        the dequantization is performed per block of size block_size along the K (input feature) dimension.
  
        If block_size and zero_point are provided, both hidden_size and inter_size must be divisible by block_size * pack_size,
        where pack_size = 8 / expert_weight_bits.
  
        The SwiGLU (Swish-Gated Linear Unit) activation function is like:
           g = xW + b
           l = xV + c
           G = clamp(g, max=limit)
           L = clamp(l, min=-limit, max=limit)
           swiglu = G * sigmoid(alpha * G) * (L + beta)
        where x is the input, W and V are weight matrices, b and c are bias vectors, and alpha, beta and limit are constant float parameters.
        When swiglu_fusion=0, two GEMMs are not fused, and they are FC1 and FC3 in the inputs.
        When swiglu_fusion=1, two GEMMs are fused so that g and l are computed in a single GEMM (FC1), and g and l are interleaved on each row of size 2 * inter_size.
        When swiglu_fusion=2, two GEMMs are fused, and g and l are concatenated on each row.

### <a name="com.microsoft.QOrderedAttention"></a><a name="com.microsoft.qorderedattention">**com.microsoft.QOrderedAttention**</a>

  Quantized version of simplified Multi-Head Self Attention(using int8 with specific matrix Layout).
  Multi-Head Self Attention that can be either unidirectional (like GPT-2) or bidirectional (like BERT).
  The mask_index input is optional. Besides raw attention mask with shape (batch_size, past_sequence_length + sequence_length)
  or (batch_size, sequence_length, past_sequence_length + sequence_length) with value 0 for masked and 1 otherwise,
  we also support other two formats: When input has right-side padding, mask_index is one dimension with shape (batch_size),
  where value of each element is the end position, or valid length of actual sequence excluding padding. When input has
  left-side padding, mask_index has shape (2 * batch_size), where the values are the exclusive end positions followed by
  the inclusive start positions. When unidirectional is 1, and each token only attend to previous tokens. For GPT-2, both past
  and present state are optional. Present state could appear in output even when past state is not in input.
  Current version does not support past/present, attention_bias and qkv_hidden_sizes.
  TODO: Support them if needed in the future.

  Quantize (Int8) MatMul with order. Implement Y = alpha * A * B + bias + beta * C. Matrix A, B, C, Y are all int8 matrix.
  Two type of order combination supported:
    *) When order_B is ORDER_COL, order_A must be ORDER_ROW.
           bias is vector of {#cols of Y} of float32, C should be batch 1/batch_A. B could be of batch 1 or batch_A.
           Note B is reorder to ORDER_COL, or Transposed. Not Transposed first and then Reordered here.
    *) When order_B is specify ORDER_COL4_4R2_8C or ORDER_COL32_2R_4R4, orderA must be ORDER_COL32.
           MatMul will be implemented using alpha(A * B) + beta * C => Y.
           bias is not supported here. B in fact is transposed first then reordered into ORDER_COL4_4R2_8C or ORDER_COL32_2R_4R4 here.
  order_Y and order_C will be same as order_A.
  Support per column quantized weight, ie, scale_B is 1-D vector of size [#cols of matrix B].

### <a name="com.microsoft.QuantizeLinear"></a><a name="com.microsoft.quantizelinear">**com.microsoft.QuantizeLinear**</a>

  The linear quantization operator. It consumes a full precision data, a scale, a zero point to compute the low precision / quantized tensor.
  The quantization formula is y = saturate ((x / y_scale) + y_zero_point). For saturation, it saturates to [0, 255] if it's uint8, [-128, 127] if it's int8,
  [0, 65,535] if it's uint16, and [-32,768, 32,767] if it's int16. For (x / y_scale), it's rounding to nearest ties to even.
  Refer to https://en.wikipedia.org/wiki/Rounding for details.
  Scale and zero point must have same shape. They must be either scalar (per tensor) or 1-D tensor (per 'axis').

### <a name="com.microsoft.SparseAttention"></a><a name="com.microsoft.sparseattention">**com.microsoft.SparseAttention**</a>

  Block Sparse Attention used in Phi-3-small (https://arxiv.org/pdf/2404.14219).
  
  It is inspired by Sparse Transformers (https://arxiv.org/pdf/1904.10509) and BigBird (https://arxiv.org/pdf/2007.14062).
  
  block_mask can be used to configure sparse layout for different head.
  When number of sparse layout is 1, all heads have same sparse layout. Otherwise, different layouts are used cyclically.
  For example, given 4 layouts (S0, S1, S2, S3), 8 heads will have layouts like (S0, S1, S2, S3, S0, S1, S2, S3).
  
  The block_row_indices and block_col_indices are the CSR representation of block mask. The block_col_indices might contain
  paddings at the right side when different layout has different number of non-zeros in block mask.
  
  An example of block mask with 2 layouts where each layout is 4 x 4 blocks:
    [[[1, 0, 0, 0],
      [1, 1, 0, 0],
      [0, 1, 1, 0],
      [0, 1, 1, 1]],
  
     [[1, 0, 0, 0],
      [1, 1, 0, 0],
      [1, 1, 1, 0],
      [1, 0, 1, 1]]]
  
  The corresponding CSR format:
    block_col_indices = [[0,  0,  1,  1,  2,  1,  2,  3, -1], [0,  0,  1,  0,  1,  2,  0,  2,  3]]
    block_row_indices = [[0, 1, 3, 5, 8], [0, 1, 3, 6, 9]]
  
  When do_rotary is True, cos_cache and sin_cache are required. Note that the maximum sequence length supported by cos
  or sin cache can be different from the maximum sequence length used by kv cache.
  
  Only supports unidirectional attention with cache of past key and value in linear buffers.
  
  For performance, past_key and present_key share same memory buffer, and past_value and present_value too.

### <a name="com.microsoft.Tokenizer"></a><a name="com.microsoft.tokenizer">**com.microsoft.Tokenizer**</a>

  Tokenizer divides each string in X into a vector of strings along the last axis. Allowed input shapes are [C] and [N, C].
    If the maximum number of tokens found per input string is D, the output shape would be [N, C, D] when input shape is [N, C].
    Similarly, if input shape is [C] then the output should be [C, D]. Tokenizer has two different operation modes.
    The first mode is selected when "tokenexp" is not set and "separators" is set. If "tokenexp" is set and "separators" is not set,
    the second mode will be used. The first mode breaks each input string into tokens by matching and removing separators.
    "separators" is a list of strings which are RE2 regular expressions. "tokenexp" is a single RE2 regular expression.
    Let's assume "separators" is [" "] and consider an example.
    If input is
    ["Hello World", "I love computer science !"] whose shape is [2],
    then the output would be
   [["Hello", "World", padvalue, padvalue, padvalue],
   ["I", "love", "computer", "science", "!"]]
   whose shape is [2, 5] because you can find at most 5 tokens per input string.
   Note that the input at most can have two axes, so 3-D and higher dimension are not supported.
   If "separators" contains a single empty string, the Tokenizer will enter into character tokenization mode. This means all strings
   will be broken apart into individual characters.
   Similarly, if "tokenexp" is set to "." (match any single character), character tokenization mode is used.
   For each input string, the second mode searches matches of "tokenexp" and each match will be a token in Y.
   The matching of "tokenexp" is conducted greedily (i.e., a match should be as long as possible).
   This operator searches for the first match starting from the beginning of the considered string,
   and then launches another search starting from the first remained character after the first matched token.
   If no match found, this operator will remove the first character from the remained string and do another search.
   This procedure will be repeated until reaching the end of the considered string.
    Let's consider another example to illustrate the effect of setting "mark" to true.
    If input is ["Hello", "World"],
    then the corresponding output would be [0x02, "Hello", "World", 0x03].
    This implies that if mark is true, [C]/[N, C] - input's output shape becomes [C, D+2]/[N, C, D+2].
  If tokenizer removes the entire content of [C]-input, it will produce [[]].
  I.e. the output shape should be [C][0] or [N][C][0] if input shape was [N][C].
  If the tokenizer receives empty input of [0] then the output is [0] if empty input
  of [N, 0] then [N, 0].

Two consecutive segments in X connected by a separator would be divided into two tokens.

To achieve character-level tokenization, one should set the 'separators' to [""], which contains an empty string.</dd>

  Returns the upper or lower triangular part of a 2-D matrix, or batches of 2-D matrices. If the attribute "upper" is set to true,
        the upper triangular matrix is retained. Lower triangular matrix is retained otherwise. Default value for upper is true.
        Trilu takes one input tensor of shape [*, N, M], where * is zero or more batch dimensions. The upper triangular part consists
        of the elements on and above the given diagonal (k). The lower triangular part consists of elements on and below the diagonal.
        All other elements in the matrix are set to zero.
        If k = 0, the triangular part on and above/below the main diagonal is retained.
        If upper is set to true, a positive k retains the upper triangular matrix excluding k diagonals above
        the main diagonal. A negative k value includes as many diagonals below the main diagonal.
        If upper is set to false, a positive k retains the lower triangular matrix including k diagonals above
        the main diagonal. A negative k value excludes as many diagonals below the main diagonal.

### <a name="com.microsoft.Unique"></a><a name="com.microsoft.unique">**com.microsoft.Unique**</a>

  Finds all the unique values (deduped list) present in the given input tensor.
                This operator returns 3 outputs.
                The first output tensor 'uniques' contains all of the unique elements of the input,
                sorted in the same order that they occur in the input.
                The second output tensor 'idx' is the same size as the input and it contains the index
                of each value of the input in 'uniques'.
                The third output tensor 'counts' contains the count of each element of 'uniques' in the input.
                Example:
                  input_x = [2, 1, 1, 3, 4, 3]
                  output_uniques = [2, 1, 3, 4]

  QEmbedLayerNormalization is the quantized fusion of embedding layer in BERT model, with optional mask processing.
  The embedding layer takes input_ids (word IDs) and segment_ids (sentence IDs) to look up word_embedding, position_embedding,
  and segment_emedding; the embeddings are added then applied layer normalization using gamma and beta tensors. The input_ids
  and segment_ids remain int32. All embeddings, gamma, and beta tensors are converted to int8/uint8. The last input mask is optional.
  If mask is provided, mask index (that is position of first 0 in mask, or number of words will be calculated.
