The OS is Mac OS Big Sur. The python version is 3.6.10. When I tried to install "numpy, pandas, matplotlib" without thinking about anything, I got the following error.
pip install matplotlib
RuntimeError: Polyfit sanity test emitted a warning, most likely due to using a buggy Accelerate backend. If you compiled yourself, see site.cfg.example for information. Otherwise report this to the vendor that provided NumPy.

ERROR: Command errored out with exit status 1: python setup.py egg_info Check the logs for full command output.
The installed version of numpy is too new. It seems. It works when 1.18 is inserted.
pip install numpy==1.18
pip install matplotlib
