| 説明 | to_npy_stack/from_npy_stack is the documented on-disk array stack format: a directory of 0.npy, 1.npy, ... chunks plus a single info metadata file. The loader deserializes that metadata file with a bare pickle.load. The stack directory is an explicitly shareable dataset format (copy/ship the directory), and mmap_mode only selects memory mapping. No parameter of the call, no dask config key, and no environment variable can block the deserialization — anyone who can supply or tamper a stack directory executes arbitrary code on every worker that reads it. Raw pickle.load is unaffected by TORCH_FORCE_WEIGHTS_ONLY_LOAD. |
