IndexError Raised While Training

[jasonyanwenl]

Hi, during training the model, the method _get_seq() in file data.py throws an IndexError. I think the reason is that the length of the given midi data is less than max_length.

Then I print the file name when this error happens and I found the midi file (after converted to pickle file) is Arciglione08.MID.pickle. The max_length is 2048 but the length of this data is 1777.

I download ecomp_piano as the input dataset. For all hyper-parameters I just use what is shown in the master branch and here is the command I used for training.
python train.py -c config/base.yml config/train.yml -m ../model

I think I could decrease the max_length to avoid this error. But could you please tell me what is the root cause of this error?

Thanks!

Hi @jasonyanwenl
Did you mange to solve this issue?

I guess this error happens because of malformated input music data. When I skip those music data, it works fine.

Actually this still happens to me and it doesn't seem to be related to the malformed data. Just that every time the file is encoded into a size smaller than max_length an error is thrown.
