Question: I have upgraded my Python to use version `3.9.1`. I have installed a module called `Pandas` which requires `Numpy`. Have followed the `pip install` commands and now when I try to import `Pandas`, I am getting an error that `Numpy` installation fails to pass sanity check.

Answer: 
Ok, discovered that the Numpy team are aware of the problem, you have to downgrade back to Numpy 1.19.3

Use Python 3.8.5. I've had a lot of problems recently regarding 3.9.x compatibility with many modules.

If you're on Anaconda use:

```
conda install python=3.8.5

```
