No module named IPython error even though its installed

[BalaDhinesh]

I have Alveo U200 connected to my cloud machine. When I run the pip install pynq-alveo-examples command, I get the error as shown in the image:

My machine has IPython already installed, but it still shows the error.

Versions: OS: Ubuntu 20.04 PYNQ: 3.0.1 XRT: 2022.2 - I have sourced XRT

Any help would be appreciated.

Hi @BalaDhinesh,

I suggest you use PYNQ for Alveo within a Conda env. The installation steps are here https://pynq.readthedocs.io/en/latest/getting_started/alveo_getting_started.html#install-conda

Please, next time use the pynq.io forums to request support.

Mario

I apologize for not utilizing the appropriate channel for seeking support. Sure, I won't repeat this again.

I tried with conda env as well. It produces similar error.

Can you try

pip install pynq-alveo-examples --no-build-isolation

Alternative, you can clone the repo locally and remove this line

https://github.com/Xilinx/Alveo-PYNQ/blob/d285dfdcf81403d06f38acefa43b5e4e26eabcfd/setup.py#L73

Then do pip install from the local repo?

[BalaDhinesh]

That works. Thanks a lot, @mariodruiz!

[mariodruiz]

which one?

[BalaDhinesh]

pip install pynq-alveo-examples --no-build-isolation works
