ok something was changed
one needs to have read write keys in sync between circle ci and github

@robintibor
on master it seemed to work again after I added this user key
I also reran the one you linked above and it succeeded now https://app.circleci.com/pipelines/github/braindecode/braindecode/450/workflows/24366b0c-fee0-4663-bfc1-90023ee4326c/jobs/544

Hi all, we are a team of students in Singapore investigating the relationship between environment, physiological measurement and electroencephalography. Currently, we are using deep learning to connect EEG measurement and other data types. We currently intend to use EEG data as input for our regression model to predict other measurements. As we have never used deep learning on EEG data before we do not know how to start. We are using OpenBCI cyton so the EEG data that we stored are in txt file – which can be made into numpy array. We are intending to use Braindecode, we did manage to store our data as MNE raw arrays and after reading the documentation, we managed to create a BaseConcatDataset (we are not sure if we set the parameters for create_from_X_y correctly, I am still not sure on the meaning of window in the structure). After that we are not what preprocessing method and regression parameters to use. Thank you very much for your help.

Hi
Maybe this tutorial can help you a bit? https://colab.research.google.com/drive/1B-5K7dNyfyu-UIVFp3A1BvgQGkZmLWrg#scrollTo=6cpFJHF0CGYS

Thank you for the link, I have finished most of it, and got the model to start running but when there are multiple targets in the regression model ( I follow the regression example in braindecode.org), I encounter this error:

AttributeError Traceback (most recent call last)

<ipython-input-11-596ca18789b8> in <module>()
112 )
113
--> 114 regressor.fit(train_set, y=None, epochs=n_epochs)

365 if self.is_regression:

367 else:
368 y = y.type(torch.int64)

AttributeError: 'list' object has no attribute 'type'

Thank you for your help

hmh did you figure out a solution? I guess if you could make sure that the ys are somehow not a list would be good, like that they are tensors already ... not sure... maybe we alsoneed to fix on our side @anhnguyenducminh

Hi @robintibor
The new version of MOABB (0.4.5) is out and your PR on the updated dataset is included. I just pushed it on PyPi, it should be available soon.

hey @robintibor,
In the end I really needed the permission in your folk. Thank you!

Hi all, through the braindecode website i was directed to this chat to find help with my issue. I am trying to reproduce this example (#3: k-fold cross validation - https://braindecode.org/master/auto_examples/plot_how_train_test_and_tune.html#sphx-glr-auto-examples-plot-how-train-test-and-tune-py), but using cropped decoding for my model instead of trialwise decoding as was used in the example here. I am unable to make this example work for cropped decoding, can anyone direct me to an example? I can make everything work with my data up until the cross_val_score() function from sklearn.model_selection). If necessary, I can provide screenshots in a private message, as the data I am using is confidential. Thanks in advance!

Hello Gigi!

@bruAristimunha

How cool that you are using the new braindecode tutorials! We were happy with that. I can help you, but using the issue system, okay?

Copy and paste what you wrote here and try to put a minimum code so we can reproduce your error. Please do not put your confidential data; try to reproduce the error with the same data from the tutorial. I feel this is an issue with the cropped option, given the way it does the slicing, but we need to reproduce it to be sure. If it's just a problem with your code or a problem with braindecode, we can solve it.

Please let me know if you need assistance opening the new issue, @gigivis_gitlab

Hello! I forgot to mention the specific error I receive: "ValueError: not enough values to unpack (expected 3, got 2), which directs me to line 179 in classifier.py from the braindecode package
1 reply
Ah yes of course, I will try and reproduce the error with the data from your example and I will report back, thank you!

I was able to reproduce the exact same error! What I did: follow the entire tutorial from this link (https://braindecode.org/master/auto_examples/plot_bcic_iv_2a_moabb_cropped.html), but I added the following from the previous link: create the X_train and y_train objects and the corresponding train and val subsets, and rather than fitting the model with "clf.fit(train_set, y=None, epochs=n_epochs)", I used the CV-approach: "from sklearn.model_selection import KFold, cross_val_score
train_val_split = KFold(n_splits=5, shuffle=False)
fit_params = {"epochs": n_epochs}
cv_results = cross_val_score(
clf, X_train, y_train, scoring="accuracy", cv=train_val_split, fit_params=fit_params
)"
Using this, I get the error that I mentioned above. Hope that is clear enough wrt describing minimum code!

Nice! Can you copy this text and put on an issue: https://github.com/braindecode/braindecode/issues/new

Hello! I am a beginner using Braindecode and I'm trying to get the basic trialwise decoding model running
When training the model I'm only getting repeated "Loading data for 1 events and 10000 original time points ..." messages and I'm not sure what is going on
