Hi @FELLOUH_Ayoub

You need to source the PYNQ environment before running Python scripts:

> Hi @DiogoBaptista There is three steps to running PYNQ code from the command line: Make sure you are in sudo privileges (e.g. sudo su) Source the pynq venv environment source /etc/profile.d/pynq\_venv.sh Source the xrt environment source /etc/profile.d/xrt\_setup.sh You should now be in the right environment to run PYNQ code. You could put both source commands into a shell script which you can run whenever you want. Thanks, Josh
