Hello Chen,

Great work there! I am really enjoying it so far!

I only have a small issue. After the adv examples are crafted and the code starts evaluating on transferability on other models, everything runs smooth until it's time for the tf2torch_adv_inception_v3.npy to be evaluated. Then the code crashes and I get the following error :

" *****Transfer to tf2torch_adv_inception_v3**** Traceback (most recent call last): File "/users/40241245/work/scripts/DiffAttack/torch_nets/tf2torch_adv_inception_v3.py", line 14, in load_weights weights_dict = np.load(weight_file, allow_pickle=True).item() File "/users/40241245/.local/lib/python3.8/site-packages/numpy/lib/npyio.py", line 417, in load fid = stack.enter_context(open(os_fspath(file), "rb")) FileNotFoundError: [Errno 2] No such file or directory: 'pretrained_models/tf2torch_adv_inception_v3.npy'

During handling of the above exception, another exception occurred:

Any ideas or advise on this? Many Thanks!

Hi @Nikos-86 ,

Thank you for reaching out. Please ensure the pretrained weights have been downloaded beforehand. You can find detailed instructions in the requirements section of the README.md file:

Hope this helps.

Hi again Chen!

Yes, just myself not paying proper attention to the information provided... Not the first time this happens! :P

It's working just fine now!

Many thanks for your prompt reply and once again, big congratulations for your work folks! It's really great!

Have a nice day!
