Python LogicError: clGetPlatformIDs failed: platform not found khr

When testing the nose for a set of Python programs in Ubuntu, an error occurs:

devices = [ d for d in cl.get_platforms()[0].get_devices() if
LogicError: clGetPlatformIDs failed: platform not found khr


File "/home/fateeva/prog/deflectometry/SGMFMeasurement/_PhaseShifts.py", line 30, in <module>
    devices = [ d for d in cl.get_platforms()[0].get_devices() if
LogicError: clGetPlatformIDs failed: platform not found khr

How can this be fixed?

this is an error try this:

sudo apt-get install nvidia-settings
sudo nvidia-smi

or run it (without sudo) as root.

After that you can start it.

add

nvidia-smi

in /etc/rc.local (of course, before exiting), so your GPU will be available after each boot.
