1.9.0
3c7a88f

Added

  • An option to print cached variables from CMake
  • Add support for compiling on Mac (and clang)
  • An option for resetting stalled validation metrics
  • Add CMAKE options to disable compilation for specific GPU SM types
  • An option to print word-level translation scores
  • An option to turn off automatic detokenization from SentencePiece
  • Separate quantization types for 8-bit FBGEMM for AVX2 and AVX512
  • Sequence-level unliklihood training
  • Allow file name templated valid-translation-output files
  • Support for lexical shortlists in marian-server
  • Support for 8-bit matrix multiplication with FBGEMM
  • CMakeLists.txt now looks for SSE 4.2
  • Purging of finished hypotheses during beam-search. A lot faster for large batches.
  • Faster option look-up, up to 20-30% faster translation
  • Added --cite and --authors flag
  • Added optional support for ccache
  • Switch to change abort to exception, only to be used in library mode
  • Support for 16-bit packed models with FBGEMM
  • Multiple separated parameter types in ExpressionGraph, currently inference-only
  • Safe handling of sigterm signal
  • Automatic vectorization of elementwise operations on CPU for tensors dims that
    are divisible by 4 (AVX) and 8 (AVX2)
  • Replacing std::shared_ptr with custom IntrusivePtr for small objects like
    Tensors, Hypotheses and Expressions.
  • Fp16 inference working for translation
  • Gradient-checkpointing

Fixed

  • Replace value for INVALID_PATH_SCORE with std::numer_limits::lowest()
    to avoid overflow with long sequences
  • Break up potential circular references for GraphGroup*
  • Fix empty source batch entries with batch purging
  • Clear RNN chache in transformer model, add correct hash functions to nodes
  • Gather-operation for all index sizes
  • Fix word weighting with max length cropping
  • Fixed compilation on CPUs without support for AVX
  • FastOpt now reads "n" and "y" values as strings, not as boolean values
  • Fixed multiple reduction kernels on GPU
  • Fixed guided-alignment training with cross-entropy
  • Replace IntrusivePtr with std::uniq_ptr in FastOpt, fixes random segfaults
    due to thread-non-safty of reference counting.
  • Make sure that items are 256-byte aligned during saving
  • Make explicit matmul functions respect setting of cublasMathMode
  • Fix memory mapping for mixed paramter models
  • Removed naked pointer and potential memory-leak from file_stream.{cpp,h}
  • Compilation for GCC >= 7 due to exception thrown in destructor
  • Sort parameters by lexicographical order during allocation to ensure consistent
    memory-layout during allocation, loading, saving.
  • Output empty line when input is empty line. Previous behavior might result in
    hallucinated outputs.
  • Compilation with CUDA 10.1

Changed

  • Combine two for-loops in nth_element.cpp on CPU
  • Revert LayerNorm eps to old position, i.e. sigma' = sqrt(sigma^2 + eps)
  • Downgrade NCCL to 2.3.7 as 2.4.2 is buggy (hangs with larger models)
  • Return error signal on SIGTERM
  • Dropped support for CUDA 8.0, CUDA 9.0 is now minimal requirement
  • Removed autotuner for now, will be switched back on later
  • Boost depdendency is now optional and only required for marian_server
  • Dropped support for g++-4.9
  • Simplified file stream and temporary file handling
  • Unified node intializers, same function API.
  • Remove overstuff/understuff code
