Error when loading Lee2019_SSVEP dataset

[AlexandreBleuze]

Hi,

I'm currently working on SSVEP paradigm and trying to load the Lee2019_SSVEP dataset. However when loading it with SSVEP filter-bank paradigm, I'm getting the following error "RuntimeError: events cannot be set directly."
I think the error is comming from a manipulation in MNE that is not allowed, from what I searched but I can't get passed it.
My versions are :
Python 3.9.10
Moabb 0.4.6
MNE 1.0.3

A simple code to give the error would be :

from moabb.datasets import Lee2019_SSVEP
from moabb.paradigms import FilterBankSSVEP

# Does not work when settings events and filters
moabb_paradigm = FilterBankSSVEP(n_classes=2, events=["8.57", "12.0"], filters=[[8.1, 9.1], [11.5, 12.5]])

# Does not work much when just setting a number of classes
# moabb_paradigm = FilterBankSSVEP(n_classes=2)

dataset = Lee2019_SSVEP()
Xt, yt, _ = moabb_paradigm.get_data(dataset=dataset, subjects=[1])

I also join a screen of the error I'm getting if you are interested.

I could reproduce the error with newer version of MNE (> 1.0.0). With older MNE versions (like 0.24.1), both settings events+filters or n_classes are working, I obtain Xt signal of shape (100, 62, 4001, 2) and (100, 62, 4001, 2)

I'll try to use an older version of MNE then. Do you think it is possible to solve this problem for the newest version of MNE ?

Yes, I'll fix it in an upcoming PR.
