Hi Shishankjan.

Thanks for sharing this.

It's hard to tell from your screenshots what exactly you did ( eg what did you type on the cli) that raised this error. Can you please clarify that ?

[shishankjain]

For checking signal: eegnb checksiqual -ed cyton @JohnGriffiths

[shishankjain]

After running the test code on the jupyter notebook, I am getting the same issue.

I am facing issue on this line: from eegnb.devices.eeg import EEG

It is not able to import EEG or something.

[JohnGriffiths]

Ok. Looks like everything is correct on the eeg-notebooks side but there is an issue with your brainflow installation.

Can you try:

pip uninstall brainflow

pip install -U brainflow

ipython

from brainflow import BoardShim

Does this throw the same error ?

[shishankjain]

Yes it is also throwing the same error. @JohnGriffiths

@shishankjain It it hard to figure out the cause of this without the full logs. Please paste them in full instead of screenshots.
