Python TA-LIB error on Mac - Symbol not found: _TA_ACOS

I'm trying to use TA-lib in my Python programming.

I followed the instructions here: http://mrjbq7.github.io/ta-lib/install.html but kept running into errors. After a bit of trial and error (I am not a Mac expert having grown up on PCs!) I eventually got it installed after installing Brew, updating to Python 3.8.5 (Conda) and uninstalling the other version (3.9.2) that I had unwittingly installed outside Conda.

Now, when I call it from within my Python code using "import talib as ta", I get the following error:

(base) jasoncameron@Jasons-Mac-mini python % python app_prepdata.py

There are some references to this error on other sites but no solutions and given it appears to have been installed successfully, I'm at a loss! Please let me know if you have any thoughts.

I'm running a new M1 Mac/Big Sur (not sure if that makes a difference) and have the following packages installed:
