How to install brian2 on pynq z1 board?

I wanted to implement snn on pynq so I tried to install brian2.
The following message keeps popping up whenever I try. - “WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by ‘NewConnectionError(’<pip._vendor.urllib3.connection.HTTPSConnection object at 0xb4fbb028>: Failed to establish a new connection: [Errno-3] Temporary failure in name resolution’)': /simple/brian”

Hi @Shan_11,

Welcome to the PYNQ community.

This is likely because your board does not have access to the Internet.
There are a few similar issues in the forum.
