Hello, thank you for your sharing. I try to run the coding, but there is always an index error that I cannot handle. Could you please help me with that? I would appreciate it.

The error is as follows:

IndexError Traceback (most recent call last) /var/folders/5x/3g67fwns0mb68s__c_3fk4wr0000gn/T/ipykernel_43899/857709293.py in 10 outputfilename2 = "./inputfiles/yy" + str(windowsize) + "" + str(threshold) + "_" + label + ".csv" 11 ---> 12 x, y = dataimport(filepath1, filepath2) 13 with open(outputfilename1, "w") as f: 14 writer = csv.writer(f, lineterminator="\n")

IndexError: only integers, slices (:), ellipsis (...), numpy.newaxis (None) and integer or boolean arrays are valid indices

It seems that the author used Python 2, but you are using Python 3 So k/slide_size will yield a float for Python3 which are invalid indices. You may change k/slide_size to k//slide_size to fix the issue.

Thank you so much. That makes sense.
