I am trying to use a network for classification. This network works very well on the author's example data, but doesn't work on new data.

Currently, I am using the popular EEG Motor Movement/Imagery Dataset, where other people arrived at ~80% accuracy. I got this accuracy with brain decode (CNN).

Now, I am trying to classify this data using EEGLearn (RNN-CNN), but I'm still on the chance level. Do you have any suggestions?

The implementation of any neural network needs precise feature engineering on your dataset. Neural network is very tailored solution. In case of classification, braindecode uses SignalAndTarget class. This is where signal is mapped on x axis and target label is on y axis.

You have to check whether you're following the same mapping. EEG learn is using time series data and implementation is done in tensorflow.

My advise would be to relatively scale the data into time scale used in EEG method.
