Release v1.2.0

Release Notes

• You can now use $HOME and $USER in your configuration files.
• Fixed an overflow error that would cause NMT with more than 255 tokens to fail.
• METEOR worker process is now correctly killed after validations.
• Many runs of an experiment are now suffixed with a unique random string instead of incremental integers to avoid race conditions in cluster setups.
• Replaced utils.nn.get_network_topology() with a new Topology class that will parse the direction string of the model in a more smart way.
• If CUDA_VISIBLE_DEVICES is set, the GPUManager will always honor it.
• Dropped creation of temporary/advisory lock files under /tmp for GPU reservation.
• Time measurements during training are now structered into batch overhead, training and evaluation timings.
• Datasets
  • Added TextDataset for standalone text file reading.
  • Added OneHotDataset, a variant of TextDataset where the sequences are not prefixed/suffixed with <bos> and <eos> respectively.
  • Added experimental MultiParallelDataset that merges an arbitrary number of parallel datasets together.
• nmtpy translate
  • .nodbl and .nounk suffixes are now added to output files for --avoid-double and --avoid-unk arguments respectively.
  • A model-agnostic enough beam_search() is now separated out into its own file nmtpytorch/search.py.
  • max_len default is increased to 200.
