Preparing wheel metadata ... error while installing alveo examples

[Alvir-Islam]

Hello, I was trying to install pynq on my alveo system. I followed your documentation for the installation. However, while I was trying to execute the pynq-alveo-examples command, the following issue came up.

(base) myterminal@alveo:~$ pip install pynq-alveo-examples --no-build-isolation

Hi @Alvir-Islam,

You need at least Python 3.8 to use pynq >= 3.0.0, otherwise you will have to install an older pynq version

This was helpful. I have installed pynq 2.7.0 and it is working now. Thank you Mario.
