pyopencl.RuntimeError: clWaitForEvents failed: exec status error for events in wait list

709 Views Asked by At

Every so often I am not able to continue to run PyOpenCL on my machine. This occasionally happens if I kill a process that is using it. Across ALL pyopencl scripts/kernels, including examples I find online I get the following error:

pyopencl.RuntimeError: clWaitForEvents failed: exec status error for events in wait list

which follows any call of the form

kernel.(queue,gs,ls,...).wait()

OR a = kernel.(queue,gs,ls,...) a.wait()

Rebooting my machine resolves the issue, but this is a painful work around. Has anyone run into anything similar and know how to reset things?

Thank you
