Unable to install packages

[vtechzbi]

The error messages show connection error, so it's either internet connection not established, or firewall is stopping connection.
if you are able to download files, you can download a wheel here: https://pypi.org/project/pandas/#files
and then run pip3 wheelname

Yes its like some firewall block. DO you know which port we need to unblock. Also I have tried downloading the whl file but don't know how to install the same.
