mindspore.unified_safetensors
- mindspore.unified_safetensors(src_dir, src_strategy_file, dst_dir, merge_with_redundancy=True, file_suffix=None)[source]
Merge multiple safetensor files into a unified safetensor file.
- Parameters
src_dir (str) – Source weight saving directory.
src_strategy_file (str) – Source weight segmentation strategy file.
dst_dir (str) – Target save directory.
merge_with_redundancy (bool, optional) – Whether the merged source weight files are de-duplicated and saved safetensors files. Default:
True
, indicating that the merged source weight files are complete.file_suffix (str, optional) – Specify the filename suffix for merging safetensors files. Default:
None
, meaning all safetensors files in the source weight directory will be merged.
- Raises
ValueError – If the safetensors file of rank is missing.
- Supported Platforms:
Ascend
