Hi,
I am getting the following error and was wondering if you could help me fix it. I am using the sample data you provided.
Thanks!

Are you able to run the following?
import eeglearn
import eeglearn.eeg_cnn_lib as eeglib
images = eeglib.gen_images(locs, features, nGridPoints)
eeglib.train(images, labels, train_test_fold, model_type)

Thanks for the reply. Running this code produces the following error:
Traceback (most recent call last):
File "C:\Program Files\JetBrains\PyCharm 2017.3.3\helpers\pydev\pydev_run_in_console.py", line 53, in run_file

images = eeglib.gen_images(locs, features, nGridPoints)
NameError: name 'locs' is not defined
This is why I started modifying it (see my first post).

Right, it should fail as you said.
Try the following:
python eeg_cnn_lib.py
this should run and use the sample data to generate images and train the network.
