autoreject: Missing import for IPython console execution.

While trying out the new workflow tutorial, I ran into a couple of issues with the progress bars.

In a new environment, in the python console, nothing breaks, and the progress bar work. With the same environment, in the Spyder IPython console, I get:

Ah, I didn’t realize I had fallen behind the latest version. I was on 0.24.1 and I see 1.0 is now out.

I just upgraded with pip install -U mne to 1.0 and got a different error about mne/externals, which I was struggling to find in my site-packages. Then I created an entirely new conda env, which worked fine. Thanks for asking 😃

Slick new visualizations with mne-1.0!

Oh, interesting. So autoreject is in fact running into the same issue! Thanks for the clarification!

@hoechenberger I guess a similar problem is occurring with openneuro-py, but it’s not the one at cause here. In this issue, the error is caused by the progress bar displayed by AutoReject.fit(), no?

That said, with openneuro version 2021.8, I do get an error, but maybe not the one you are expecting:

Hello! This is openneuro-py 2021.8. Great to see you!

The same code snippet works in the terminal, so the error is restricted to the IPython console. I’ll check the PR code and reply on the PR.
