4 months ago @Ramzes30765 hey Adding pickle_module=dill explicitly in the torch.load function like this: torch.load('your_model.pt', pickle_module=dill) helped me. I added it in the strip_optimizer_v2 function and the torch_save_load function in the ultralytics/nn/tasks.py file. let me know if you found something else

4 months ago @jenyaMi Hello! Thank you for information
pickle_module=dill
Should I add this parameter in torch.save() too?
