Hello, everyone
I am new to use PYNQ and I follow the instruction from GitHub - Xilinx/PYNQ: Python Productivity for ZYNQ
When I used the command, sudo pip3 install --upgrade --upgrade-strategy only-if-needed pynq, I encountered an error.
ERROR: Command errored out with exit status 1:

Could someone help me?
