# This is the PyTorch mypy-strict.ini file (note: don't change this line! -
# test_run_mypy in test/test_type_hints.py uses this string)

# Unlike mypy.ini, it enforces very strict typing rules. The intention is for
# this config file to be used to ENFORCE that people are using mypy on codegen
# files.

# For now, only code_template.py and benchmark utils Timer are covered this way
