Bug description

In early steps of Demo_Allen.ipynb, trying to load ca_train with ca.datasets.init(), I get an error.

Operating System

Windows 10

CEBRA version

0.2.0

Device type

cpu 11th gen intel i7
gpu nvidia geforce rtx 3050ti

Steps To Reproduce

Code:

cortex = 'VISp'
seed=333
num_neurons = 800
ca_train = cebra.datasets.init(f'allen-movie-one-ca-{cortex}-{num_neurons}-train-10-{seed}')

Stack trace:

File ~\miniconda3\envs\cebra\lib\site-packages\cebra\datasets\allen\ca_movie_decoding.py:176, in <listcomp>(.0)
    162 """Construct pseudomouse neural dataset.
    163 
    164 Stack the excitatory neurons from the multiple mice and construct a psuedomouse neural dataset of the specified visual cortical area.
   (...)
    169 
    170 """
    172 list_mice = glob.glob(
    173     get_datapath(
    174         f"allen/visual_drift/data/calcium_excitatory/{area}/*"))
    175 exp_containers = [
--> 176     int(mice.split(f"{area}/")[1].replace(".mat", ""))
    177     for mice in list_mice
    178 ]
    179 ## Load summary file
    180 summary = pd.read_csv(get_datapath("allen/data_summary.csv"))

IndexError: list index out of range

I went into the debugger and checked out the mice string:
data\\allen/visual_drift/data/calcium_excitatory/VISp\\511498742.mat

It seems split() is getting hung up on Windows path weirdness. I have a linux machine I can switch to for running Cebra, but I just thought I'd let you know about this just in case.

Hi, similar to other issues, the demos are slightly ahead of the stable release, so please install 0.3.0rc1 ! We will update to a stable release this week, cc @stes

I upgraded, and same issue, but switched to Linux where things are good because ... don't fight the framework. 😄

[MMathisLab]

Ah, I'm sorry -- I didn't read your initial post carefully. We should fix the paths asap, @gonlairo - needs to be done for rc2.

We are working towards windows support in #79 now!
