The operator 'aten::linspace.out' is not currently supported on the ocl backend.

hit with some random torch demo I picked from the internet.

It also hits The operator 'aten::_copy_from_and_resize' is not currently supported on the ocl backend.

Ok... I think I fixed it. Hopefully did correctly. I'll check if further

Fixed in be908fd875410df72909b14727ca23a8371b42cf

Just small note it still warns on some missing ops and falls on CPU but it does not fails due to _copy_from_and_resize
