What I try is upgrade my numpy from 1.19.2 to 1.20.1 (requirement 1.18.0) but still same error, I'm using python 3.8.6

maybe the solution is to reinstall numpy. like he did here stackoverflow.com/questions/66060487/… — shv
Already upgrade from 1.19.2 to 1.20.1, actually the requirement is 1.18.0 — Nabih Bawazir
try removing it all together, and then try to install it from scratch. sometimes upgrading leave traces of the old version. — shv

I get the similar issue，when I install toad-0.0.65

pip install numpy==1.20.1 toad

And restart your current notebook for update cache，toad will work.
