   I have the exact same issue on Windows 10 64-bit, Python 3.8 with Arrow 
0.16.0 - `Requirement already satisfied: pyarrow==0.16.0 in 
c:\python38\lib\site-packages (0.16.0)`. When installing 
apache-superset==0.35.2, it fails with the error - `ModuleNotFoundError: No 
module named 'numpy'` even though Numpy is installed fine and there are no 
environment conflicts - `Requirement already satisfied: numpy in 
c:\python38\lib\site-packages (1.18.1)`.
   
   Update: I suspect this is tied to the following issue 
(https://github.com/apache/arrow/issues/5987) and since apache-superset expects 
pyarrow==0.15.1 which I am unable to downgrade to (from 0.16.0 because of the 
same issue reported above i.e. Numpy import failure) this may mean non-linux 
installations will struggle until apache superset enable pyarrow==0.16.0  Also 
conda works likely because conda-forge has an older version of apache superset 
available for Windows (0.26.3)
