Error when running plugin_explorer in Viame with Linux

[abourbou]

Hi, I tried to run ./pluging explorer in Viame0.20.2 and compiled master version on Ubuntu 20.04.
And I got an error which seems linked to python

source ./setup_viame.sh && ./bin/plugin_explorer --algo train_detector -d

Ok sorry, I made it work by sourcing in my terminal and then launch the command.
I still got some minor error messages :
