Not able to run mnist_100_full

[Duaam]

Hi !
I'm newbie in this domain and i study the method proposed in the paper as a school project,
I fixed the errors of the packages version, i downloaded the data but the second command of conversion doesn't work so i got the following error:
Traceback (most recent call last):
File "./run.py", line 652, in
if train(d) is None:
File "./run.py", line 406, in train
in_dim, data, whiten, cnorm = setup_data(p, test_set=False)
File "./run.py", line 235, in setup_data
}[p.dataset]
KeyError: 'a'
Any one has an idea about how to solve this error ?
Thank you.
