Cannot download mnist classifier model

[zzzhhh2025]

Line 81 of the installation script install_update_kr260_to_vitisai35.sh is python code

pynq get-notebooks pynq-dpu -p . --force

When I run to this line, I got a lot of errors:

The culprit is that the python code tries to download a mnist classifier model from URL: https://www.xilinx.com/bin/public/openDownload?filename=pynqdpu.tf2_mnist_classifier.DPUCZDX8G_ISA1_B4096.3.5.0.xmodel, at line 388 of /usr/local/share/pynq-venv/lib/python3.10/site-packages/pynqutils/setup_utils/deliver_notebooks.py. However, this URL is broken. How to fix the installation script so that I can proceed (I have changed the board to KR260 in line 38 of the installation script)? Thanks.

Hi @zzzhhh2025, the url works fine for me from multiple networks. You might want to check your network or firewall settings. I suspect this could be the same reason you're missing dpu.bit in #11 - during install we download from the same domain, maybe it failed silently.
