# Fickling

> Fickling decompiles and statically analyzes Python pickle serializations, including PyTorch files. python -m pip install fickling installs the library and the fickling command. Python 3.11 or newer is required. fickling --trace prints an execution trace, and Pickled.load builds an AST of a pickle. fickling[torch] adds the PyTorch modules. activate_safe_ml_environment hooks pickle and checks imports against an allowlist.
