Hi there!  
as of now, I would not reccommend pip-installing from the repo directly. We are moving away from it.

For now, please download the pynq-2.5 sdist tarball from [here](https://github.com/Xilinx/PYNQ/releases/tag/v2.5) (in particular [this](https://github.com/Xilinx/PYNQ/releases/download/v2.5/pynq-2.5.tar.gz) link)  
and then do:  
`sudo pip3 install --upgrade pynq-2.5.tar.gz`

Let me know if this works.
