Hi, I updated the Alveo U200 environment and tried to run Pynq on it. It seems that Python libraries are using the deprecated Xbutil command options. Any suggestion or workaround? Best Regards, GS ---

Hi Gustavo, This is a known bug for us, we are working on a clean solution. In the meantime, you could try this workaround Edit this line where the pynq package is > and add `--legacy`. For instance, [‘xbutil’, ‘dump’, ‘–legacy’] Mario ---

Hi Mario, Thank you for you quick response. I already made this change, because I use “–legacy” in commands for installation. To be specific, I modify …/anaconda3/lib/python3.7/site-packages/pynq/pl\_server/xrt\_device.py and I found more errors. I copy the error, just in case has an easy workaround.

```auto → 104 import nest_asyncio 105 nest_asyncio.apply() 106 ModuleNotFoundError: No module named ‘nest_asyncio’ ``` This python package is missing, you can install it using command below. I recommend you use the Jupyter Lab terminal ```nohighlight python3 -m pip install nest_asyncio ``` ---

Hi Mario, Thank you very much for the information. Now it works. Just a comment: the xclbin provided works with shell: xilinx-u200-xdma-201830.2-2580015\_18.04.deb but not xilinx-u200\_2021.2\_2021\_1021\_1001-all.deb if you run with the 2021 shell, you’ll obtain: RuntimeError: Programming Device failed: ENOTSUP (95) Operation not supported/Shell does not match Best Regards, GS ---
