I updated my 2019 Macbook Pro 15inch to Big Sur. I found that Spyder + Anaconda had a big lag, and the Spyder developers suggested just downloading the Spyder .dmg and use python through there.
But, every time I try to use pandas (I have multiple scripts that depend upon the package), I get this error:
runcell(0, '/Users/insertname/Documents/projectpath')

I'm only calling import pandas in the script, for now, for testing. I have totally scrubbed Anaconda from my computer, and have used brew install for the latest version of python (3.9.2) and have the latest Spyder version (4.2.1).
Spyder, along the bottom of the frame, says it's running python 3.9.1 - though I don't know if this has anything to do with it. I've tried pip3 uninstalling pandas and reinstalling multiple times, cleaned my computer of Spyder & python (though not the python that comes with every Mac, 2.7 I believe) - and nothing gets me past the error above.
I do not want to go back to Anaconda (at least, until the lag is gone). I've tried everything in this question - but I don't want to go the anaconda way.
