CTranslate2 3.19.0

Changes

• Binary wheels for Python 3.7 are no longer built

New features

• Build wheels for Python 3.12
• Update the Transformers converter to support more model architectures:
  • Falcon-RW
  • DistilBERT
  • Llama with linear RoPE scaling (e.g. Vicuna v1.5)
  • Llama with a non default RoPE base period (e.g. CodeLlama)
• Accept the token type IDs as inputs for encoder models
• Add property GenerationStepResult.hypothesis_id to identify the different hypotheses when running random sampling with num_hypotheses > 1

Fixes and improvements

• Improve performance of 8-bit models on CPU:
  • Vectorize the GEMM output dequantization
  • Fuse the GEMM output dequantization with bias and activation
• Allow inputs shorter than 30 seconds in Whisper methods
• Fix incorrect batch_id values passed to the callback function
• Fix a shape error in models using both MQA and relative positions
• Fix compilation error related to AVX512 when using GCC 7
• Call .detach() on PyTorch tensors before getting the Numpy array in converters
