Args: path: directory where the checkpoint will be read from. fqn_to_index_mapping: A mapping from tensor FQN to the index of the file that the tensor should be written to. Indices are from 1 to N, where N is the number of files. If not provided, the tensors will be written to a single file. If none, then all the tensors on the same rank will be written to the same file. thread_count: Number of threads to use to write distributed checkpoint. Default to 1. save_distributed: If True, save the checkpoint using distributed APIs where every rank saves its own shard. Default is False which assumes rank-0 checkpointing of the full state_dict. enable_consolidation: If True, consolidate the sharded checkpoint after saving. The sharded tensors will be saved to path/sharded and the full tensors will be saved to path. Default to False. thread_count_consolidation: Number of threads to use for parallel processing of saving data to consolidated output files.
