The error may be obvious but finding this file and how to install it
is not unfortunately.
It seems I have to install it from the National Instruments site but
Debian Linux doesn't seem to be supported...
and I doubt whether just copying this file will be sufficient to make
PyVisa work.
I wonder whether there might be another way to communicate via USB
with a Keithley programmable power supply using Python.

best regards,
