pip install ...

worked appropriately.

I uninstalled the whole python and reinstalled it again. It worked.

As per my friends advice downloaded and moved pandas-1.0.3-cp36-cp36m-win_amd64.whl & pyodbc-4.0.30-cp27-cp27m-win_amd64.whl files into site-packages. Still nothing is working.

Can someone please point out where i am wrong.
