Keras custom layer can't be saved because of duplicate weight names

[Christos Panagiotakopoulos]

I have created a custom layer for a model in keras but when I try to save it, keras throws this error:

File "h5py/_objects.pyx", line 54, in h5py._objects.with_phil.wrapper File

"h5py/_objects.pyx", line 55, in h5py._objects.with_phil.wrapper File "h5py/h5o.pyx", line 202, in h5py.h5o.link RuntimeError: Unable to create link (name already exists)

As I searched the above error, I found out that there are a couple of duplicate weight names inside my model

eg:

8 transformer_test/attention_test/dense/kernel:0 

9 transformer_test/attention_test/dense/bias:0 

10 transformer_test/attention_test/dense/kernel:0 

11 transformer_test/attention_test/dense/bias:0

The question is: What is causing those duplicate weight names? How could I prevent this from happening?

Here is the model's code. Thanks a lot in advance for your help! :)

I think that you can fix this by creating all of the inner layers (Conv1D etc.) with unique names.

If not, you will need to replace the uses of inner Layer with their tensorflow equivalents.
