Hello, based on these outputs:
Training set: n_subjects=0 Number of examples = 0
There might be no files in this directory data_dir. You can debug the code and check if there are any files in the data_dir path, also you can put a breakpoint at the below line and check this. https://github.com/MousaviSajad/SleepEEGNet/blob/2fcd73c8d5c2d499fbb78300392f432c3f3b4f3e/dataloader.py#L105

Hello thanks a lot for your answer. I tried using Google Colab and it is solved. but due to limited time I need to change the number of folds. I do it through this command in run as you said: python seq2seq_sleep_sleep-EDF.py --data_dir data_2013/eeg_fpz_cz --output_dir output_2013 --n_folds 20 but it was not applied. according to this line: tf.app.flags.DEFINE_integer('num_folds', 20, """Number of cross-validation folds.""") I changed the command to num_fold too, but it is not applied again. and run is stopped in fold 15 because of time and I can not get any results.
Hi again I guess because the name in data loader is n_folds but in sleep_sleep_seq2seq is num_folds. shouldn't these to have the same name?
Hi, You should change n_folds to num_folds like the below line: python seq2seq_sleep_sleep-EDF.py --data_dir data_2013/eeg_fpz_cz --output_dir output_2013 --num_folds 20 or change the number of folds here https://github.com/MousaviSajad/SleepEEGNet/blob/924cce632076c39fce2b7cb081bc6d0f59c8ebb6/seq2seq_sleep_sleep-EDF.py#L729 Regards, Sajad

Hi thanks a lot for your answer. I did both of them. but unfortunately it didn't work.
It should have worked! or to debug, you can track the value of num_folds by printing it.
