Issue opened in EEG-Notebooks

[github-actions]

Welcome to BrainFlow project and thanks for your contribution! We will try to fix your issue ASAP. Make sure that you have read about issue format in the docs.

[Andrey1994]

#393 check this

[JohnGriffiths]

@Andrey1994 are you saying the fix is to update to python 3.10 and it won't (ever?) work for 3.8+?

That would likely cause major dependencies headaches with other libs for us.

[Andrey1994]

using windows 10 it worked for me just fine using python 3.6 and python 3.9
when I updated to windows 11 it stopped working and I spent days debugging why... here is the full story OpenBluetoothToolbox/SimpleBLE#31 and the only solution I've found is to update python to 3.10. I even have no idea what was changed between these python versions and between windows 10 and 11

[Andrey1994]

Could anybody confirm that its ok with python 3.10.5?

[Parvfect]

So it does not error out, but any operation after found muse device is not done and it ends running.

[Andrey1994]

in your script there is only prepare_session

from brainflow.board_shim import BoardShim, BoardIds, BrainFlowInputParams

params = BrainFlowInputParams()
board_id = BoardIds.MUSE_2_BOARD

board = BoardShim(board_id, params)
board.enable_dev_board_logger()

board.prepare_session()

[Parvfect]

in your script there is only prepare_session

No for that specific screenshot for python 3.10.5 I'm running the signal quality check which normally checks the signal variance of each electrode and definitely gives an output after prepare session.

[Parvfect]

That one

[Andrey1994]

could you try one of examples from brainflow docs?

[Parvfect]

Tried following code sample adapted from the docs

import argparse
import time

from brainflow.board_shim import BoardShim, BrainFlowInputParams, BoardIds, BrainFlowPresets

BoardShim.enable_dev_board_logger()
params = BrainFlowInputParams()
board = BoardShim(BoardIds.MUSE_2_BOARD, params)
board.prepare_session()
board.start_stream ()
time.sleep(10)
# data = board.get_current_board_data (256) # get latest 256 packages or less, doesnt remove them from internal buffer
data = board.get_board_data()  # get all data and remove it from internal buffer
board.stop_stream()
board.release_session()

print(data)

You're right it works as it should, so is functional with Python 3.10.5. Got the right output etc.

But something really interesting happened after that. I tried installing eeg-notebooks which obviously failed because it's not compatible with Python 3.10.4, but after than even my brainflow stopped working with the same error

So I tried creating a new conda env with python 3.10.4 and the same problem persisted for a while and then went away. There has to be something that is happening in the installation of eegnb that is interfering w brainflow on Windows 11 probably? Some common package that is causing issues? Cause it worked perfectly until I tried installing eegnb and then the same error persisted for a while and then it became okay again. This is all really confusing.

[Andrey1994]

Unfortunately I am not an expert in eeg notebooks and dont know what it does internally and which packages it uses...

[Andrey1994]

<< So I tried creating a new conda env with python 3.10.4 and the same problem persisted for a while and then went away.

it also can be that device stuck in a wierd state.. try to reboot it and see if there is an issue.

The only solution I see is to bump eeg notebooks to python 3.10 or use bled dongle
