pyopencl access violation

[lucas-wilkins]

Some installs of pyopencl cause an access violation in kernelcl.py, line 82

cl.create_some_context(interactive=False)

This has happened on a machine without a GPU with pyopencl installed. Removing pyopencl is a work-around, but it should probably be dealt with, especially if distributions of sasview are installing pyopencl.

This code is already in a try-block. Nothing we can do in sasmodels when the C module brings down the python interpreter.

SasView doesn't need to load pyopencl until we try evaluating our first model, so users can shut off OpenCL in the fitting menu after they restart.

I suggest closing this ticket.
