Hello, Ivan. Thank you for your interest. I’m not sure under what environment you are executing the codes, however, TensorFlow 2.o is meant to be operated in colab notebook. I believe some lines will not be operated in other environments.

Anyway, in colab, the “mymodel.h5” will not be saved in your desktop directly. Rather, it will be saved in the colab server and it is prepared for your callback. I was also disturbed by the fact that I cannot get the model in my desktop but this is all that I know of. You know, it feels safe that way. I will also look up and ask other T.A’s and come back if I can reach anything that might help you.

Once again, thank you for your interest and I also want to apologize for the delayed reply. Hope this help you a bit. See you!
