New PYNQ 2.7 image got ModuleNotFoundError: No module named 'pynq' when install BNN-PYNQ

Support

Because PYNQ 2.7 has Voila addon for Jupyter notebook, So I upgraded to 2.7.

When I try to install GitHub - Xilinx/BNN-PYNQ: Quantized Neural Networks (QNNs) on PYNQ by the command line

sudo pip3 install git+https://github.com/Xilinx/BNN-PYNQ.git

But I got error message as below

I check the pynq module location.

At first I tried to report it in BNN-PYNQ github. It is sad that the github was set to read-only. Can’t file in new issue. So I have to report it here.

Hi,

BNN-PYNQ has been archived, the FINN team redirects to the finn-examples repo. There is no guarantee BNN-PYNQ will work on 2.7.

The pynq package is installed in a venv since 2.7. So, to avoid this error, you should add the --no-build-isolation switch. I recommend you run this from the terminal in JupyterLab?

python3 -m pip install git+https://github.com/Xilinx/BNN-PYNQ.git --no-build-isolation

Make sure CWD is /home/xilinx/jupyter_notebooks

You may also use image v2.6.0, this may help

Hi atopet,
Thanks for your suggestion. The BNN-PYNQ works in PYNQ v2.6.x. However I encounter package dependence issue when install Volia. That is why I move to v2.7.0

Hi marioruiz,
I run into Jupyter Lab terminal, the result is same. So I will take a look of FINN-example for v2.7.0

Once you have install all dependencies successfully for v2.7.0, you don’t need to rerun the dependencies for v2.6.x again, however, if necessary, you may just adjust your script or makefile for v2.6.x to match the viola version previously already installed.

Did you also try @marioruiz command? python3 -m pip install git+https://github.com/Xilinx/BNN-PYNQ.git --no-build-isolation

You are missing the --no-build-isolation switch. I tested this in a 2.7 image and worked for me.

Ha! My bad eyes sight caused this switch was missing. After add this switch and run in Jupyter Lab terminal. BNN works again! Thanks for your great help.

Hi,
I successfully installed BNN-PYNQ on pynq 3.0.1 using the command root@pynq:/home/xilinx/jupyter_notebooks# python3 -m pip install git+https://github.com/timoteogb/BNN-PYNQ-ZCU104.git --no-build-isolation.
Thanks @marioruiz .
