hey! i'm having the same problem - did you happen to find a solution?
thanks!

@zsheill7 Sorry , but i was unable to get a solution.Sed:(

Hi,

This is due to inconsistencies between the model and the data you're using. If you make changes to the data then you have to train the model again so that you can generate songs.

[naganikshith04]

@Skuldur that means we need to train the model again?thank you.

[Skuldur]

Yes, you need to train the model again using your data and then use the weights file generated by training the model to generate sequences of notes. :)

The weights I have included in the repository only works with the data that's provided in the repository.

[naganikshith04]

@Skuldur i was usung your weights and data you have provided ...but this error has arised.

[Skuldur]

Okay, I'll look into this after work today. Finally have some time due to social isolation.

@Skuldur Thankyou so much!

Hi,

I just pulled the repository into a clean directory and running predict.py worked perfectly. Are you certain that you didn't make any changes to any file after clone the repository?

[naganikshith04]

@Skuldur Thankyou very much. I will again clone the repo and try it again sorry man! :).

Still facing the issue, any clue? If I run a few epochs it works, any clue?

[Skuldur]

If you change the dataset and the data/notes file then you have to retrain the model because the amount of different notes and chords will differ from what the model is expecting.

Hi @Skuldur. The Weights doesn't fit the model used in the predict.py. It has nothing to do with the data set. Could you share the model you used for training? That'll be very helpful. Thanks.

Hi,

I just pulled the repository into a clean environment on my work computer and

1. Running predict.py directly worked perfectly.
2. Training a model using lstm.py and using the weights from that model in predict.py worked perfectly.

Are you certain that you didn't make any changes to any file after clone the repository? Predict.py uses data/notes to get information on dimensions. If you run lstm.py, that file gets overwritten with information corresponding to your current dataset.

I think it is not a problem of coding. It is the problem of communication.
For these who get the value error, simple open predict.py and make following changes should help.
After we train the model, we will get new weights file called weights improvement or something like that.
Simple replace the name of this file to weights.hdf5 should solve the issue. Have a nice music. This programe is awesome.
