I figured the files had to be unzipped in the raw folder, but after that my pc completely freezes while running the script.

@Looper2074 Have you determined what line the script may be stuck at? Assuming you got the files unzipped to the right place, it's perhaps somewhere within create_events_hdf5(here). You might try stepping through the code with pdb to figure out which part may be causing the trouble.

(It doesn't necessarily help you solve the problem, but I will say I was able to get this to run myself, so I can vouch that once you've downloaded the data it does work, even if it might take a while to process.)

The script constructs an hdf5 version of the dataset which may take a while. This is a torchneuromorphic issue though.
