I'm not sure how I solved it, I think it was something related to paths or slash. something like that. Good luck!

I was getting a similar error. The solution is to fill up the concerned config.json file parameters. In my case, I had to input a non-null value for config[‘train’][‘saved_weights_name’]. Hope this helps.

modify f = h5dict(filepath, mode='w') to f = h5dict(str(filepath), mode='w')

Thankyou rohitbhio

**> modify f = h5dict(filepath, mode='w') to

f = h5dict(str(filepath), mode='w')**

In which file does this exist ?

[HAMZARaouia]

Thankyou rohitbhio

where did you add the line of code proposed by rohitbhio ?

@HAMZARaouia , As you can see from the stack trace,

File "/usr/local/lib/python2.7/dist-packages/keras/engine/saving.py", line 379, in save_model.

This is where you need to make the modification.
