Hi, I was using this library but I got this error when reloading (after successfully training).

File "/home/THEUSER/anaconda3/envs/tf_gpu/lib/python3.9/site-packages/tensorflow/python/keras/saving/save.py", line 206, in load_model

Do you know how to fix it ? Thanks a lot.

Have you copied the losses.py 's functions to your code before calling it? If not then do try that.
