Pynq DPU in Ultra96 basic steps

[gustandil]

Hi,

I downloaded the new Pynq 2.7 image for ultra96v2.
After that, following the Pynq-DPU instructions

GitHub - Xilinx/DPU-PYNQ: DPU on PYNQ

I installed successfully (at least no errors):
pip3 install pynq-dpu --no-build-isolation

In next step (download the notebooks)
pynq get-notebooks pynq-dpu -p .
Fails with following message:

Any idea or Suggestion?
Any ultra96v2 user that had tested and succeed?

Best Regards, GS

HI @gustandil,

I think is best if you run these steps from the Jupyter Labs terminal, as discussed in this thread

Accessing an overlay from multiple python interpreters

That isn’t my experience. I’ve now updated to pynq 2.7 and of a fresh sd image do the following: ssh in sudo ipython import pynq pynq.Overlay(path_to_my_bitstream, download=False) This results in RuntimeError: No Devices Found as does executing the command with download=True I do get the warning /home/xilinx/pynq/pl_server/device.py:79: UserWarning: No devices found, is the XRT environment sourced? Looking through systemd services I make my way to pl_server.sh and see that there are ind…

pynq is installed in a virtual environment since the SD card image 2.7.

In this case PYNQ-DPU is not being installed in the virtual environment which seems to be the problem

Hi Mario!

You have right. It works!
I run from the Jupyter Labs terminal and everything goes smoothly.

P.S. I suggest adding the advice in Pynq-DPU instructions.
