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](https://github.com/Xilinx/BNN-PYNQ) by the command line

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

```

But I got error message as below

```auto

```

I check the pynq module location.

```auto
sudo pip3 show pynq

Version: 2.7.0

```

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BNN-PYNQ has been archived, the FINN team redirects to the [finn-examples](https://github.com/Xilinx/finn-examples) repo.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?

```nohighlight
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 .
