Dear Chikakoyanagida,

First of all, it looks like you do not have Python in your $PATH. I would suggest you add this and try again.

Best regards,
Daniel Staros

I ran into this issue on Ubuntu 22.04, where 'python3' is the only python executable installed by default. It looks like most places in the QP2 source have been updated to use 'python3' instead of 'python' for the executable name, but there must be some places where the update was missed.
