Summary of Changes

Hello @hiworldwzj, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refining the dependency installation process within the CUDA 12.8.0 Docker environments. The changes aim to enhance build efficiency by utilizing Docker's build cache for pip installations and ensuring that PyTorch-related dependencies are fetched from the correct index URL tailored for CUDA 12.8.0, thereby improving the reliability and speed of Docker image creation.

Highlights

  • Docker Build Optimization: The pip install commands in several Dockerfiles have been updated to leverage Docker's build cache using --mount=type=cache, which can significantly speed up subsequent builds by caching downloaded packages.
  • PyTorch Wheel URL Update: The extra-index-url for PyTorch wheels has been standardized or updated across the affected Dockerfiles to https://download.pytorch.org/whl/cu128, ensuring compatibility with CUDA 12.8.0.
  • Pip Installation Flags: The --no-cache-dir flag was removed and --ignore-installed was added to the pip install commands, which helps manage package installations more robustly within the Docker environment.

Code Review

This pull request updates several Dockerfiles to modify the pip install command for Python dependencies. The changes introduce build caching for pip, which is a good improvement for build times. However, a critical issue has been introduced in all modified Dockerfiles: the --extra-index-url for PyTorch points to a non-existent wheel index (cu128 or cu124). This will cause the Docker builds to fail. I've provided suggestions to correct these URLs to the proper index for CUDA 12.x, which is cu121.

COPY ./requirements.txt /lightllm/requirements.txt
RUN pip install -U pip
RUN pip install -r /lightllm/requirements.txt --no-cache-dir
RUN --mount=type=cache,target=/root/.cache/pip pip install -r /lightllm/requirements.txt --ignore-installed --extra-index-url https://download.pytorch.org/whl/cu128

The PyTorch wheel index URL https://download.pytorch.org/whl/cu128 appears to be incorrect. The cu128 index for PyTorch wheels does not exist, which will cause the Docker build to fail. For CUDA 12.x compatible PyTorch versions, the correct index is cu121. Please update the URL to use the correct index.

RUN --mount=type=cache,target=/root/.cache/pip pip install -r /lightllm/requirements.txt --ignore-installed --extra-index-url https://download.pytorch.org/whl/cu121

COPY ./requirements.txt /lightllm/requirements.txt
RUN pip install -U pip
RUN pip install -r /lightllm/requirements.txt --no-cache-dir

critical

The PyTorch wheel index URL has been updated from cu124 to cu128, but both https://download.pytorch.org/whl/cu124 and https://download.pytorch.org/whl/cu128 appear to be incorrect. Neither of these indices for PyTorch wheels exist, which will cause the Docker build to fail. For CUDA 12.x compatible PyTorch versions, the correct index is cu121. Please update the URL to use the correct index.

RUN --mount=type=cache,target=/root/.cache/pip pip install -r /lightllm/requirements.txt --ignore-installed --extra-index-url https://download.pytorch.org/whl/cu121
