Keras: Model save error: RuntimeError: Unable to create link (Name already exists)

[jingweimo]

I just recently update keras, and run my old codes. The trained CNN model cannot be saved for some reason, which makes me has to turn back to the old keras at this moment.

 model.save(os.path.join(modelDir,'M48DA_ACDCRT.h5'),overwrite=True)
 Traceback (most recent call last):

I also get this problem. Sometimes I save a model and it works fine. Other times I get this error. Then later I run the same code - pretty sure I have not changed anything - and it saves fine again.

I had the same issue after I applied a custom kernel regularizer to my model, but there is no problem using save_weights_only=True.
