Noob help with "No module named _multiarray_umath" on Mac Catalina with HomeBrew

Hello;

I'm a noob python programmer and I am on a mac running catalina 10.15.  I installed python with HomeBrew (pip3) and I am writing a "simple" script to manipulate/redact PDFs and images.  Key modules in use are pytesseract and magick wand (ImageMagick binding). 

It was almost working perfectly.....and then all hell broke loose.

The script was running fine until I tried to add in OpenCV.  Once I installed that package via pip, I started getting the dreaded "No module named _multiarray_umath" error.

It looks to me that pytesseract is broken now as a side-effect of the OpenCV install.  I've tried uninstalling and reinstalling several modules, and I've tried manipulating the path.

The real problem is that I am a noob, and I just don't know much about Python.

I'm hoping to get some noob-friendly kind suggestions regarding what to check.   

Any help appreciated.

Thanks!
Mark
