Hi

I have a problem with the inference_model function.

When I am executing the cell

inference_summary = summary(inference_model)
comparator(inference_summary, music_inference_model_out)

I obtain this error:

“The layer “dense” has multiple inbound nodes, with different output shapes. Hence the notion of “output shape” is ill-defined for the layer. Use get_output_shape_at(node_index) instead.”

I did not find what is wrong:
out.shape is (None, 90)
and x.shape is (None, 1,90) except after argmax(None,) and one_hot (None,90)

Thank you for your help.

Try this thread:

C5 W1 A3: Jazz Improvisation with LSTM (Problem and Tips)

For djmodel(). check these common issues: slicing X correctly. using the “reshaper()” and “densor()” functions with the appropriate arguments. used LSTM_cell() with the appropriate “inputs=” and “initial_state=[… ]” arguments. For music_inference_model(), the common errors are: Instruction 2.D tells you for argmax, use the arguments ‘out’ and ‘axis=-1’, and it says for onehot to use the arguments ‘x’ and ‘depth=n_values’. Instruction 2.E gives you the exact code to use for RepeatVector. Fo…

Thank you very much. I restarted the notebook and now it works!
