Error while using \scripts\attacks.py"

[SayanGiri1985]

am getting the following error while running \scripts\attacks.py":

fmodel = foolbox.models.PyTorchModel(model, # return logits in shape (bs, n_classes)
TypeError: init() got an unexpected keyword argument 'num_classes'

[SayanGiri1985]

Resolved the above but now getting the following error:
pred_label = np.argmax(fmodel.batch_predictions(b), axis=1)
AttributeError: 'PyTorchModel' object has no attribute 'batch_predictions'

I commented out couple of lines to get read of the above error. Now I am getting the following errors:
att = fa.DeepFoolL2Attack(fmodel)
AttributeError: module 'foolbox.attacks' has no attribute 'DeepFoolL2Attack'
