Cellpose-2D notebook: model folder does not exist

[pwetterauer]

Training the model ends with following error caused in line 45:
FileNotFoundError: [Errno 2] No such file or directory: '/content/Cellpose1/train_folder/models'

"Cellpose1" was my selected name for the model. In the train_folder directory there are no folders, only the images and masks for training.

I ran the notebook on Colab.
