kernel error - again dll
Hi
I am trying to run the SSVEP_load_and_visualize.ipynb notebook, and I get a kernel error (python 3.8, Windows 10), see below.
I tried the same on Ubuntu 18 and no error there

ImportError: DLL load failed while importing win32api: The specified module could not be found.
This all seems like code in jupyter_core? Weird that it gets called/imported?
Anyway, pretty sure it's caused by pywin32 being missing. You can probably install it with pip install pywin32.
Maybe we should add it to deps? (I depend on it in other projects and it's been hassle-free)
maybe, it was on another PC that I don't have at the moment. Gonna try in July but makes sense
