Hi all, Since updating to version 2015.2.4. some of the image creation/reading function that use to work are throwing errors on my machine. Specifically, running the following minimal code that creates an OpenCL Image from an array and reads it back: #--------------code from __future__ import print_function import numpy as np import pyopencl as cl ctx = cl.create_some_context(interactive=False) queue = cl.CommandQueue(ctx) data = np.random.randn(100,100).astype(np.float32) im = cl.image_from_array(ctx, np.asarray(data)) out = np.empty_like(data) cl.enqueue_copy(queue,out,im, origin = (0,0), region = (100,100)) print(np.allclose(data,out)) #--------------/code results in the following error* pyopencl.cffi_cl.RuntimeError: clcreateimage failed: IMAGE_FORMAT_NOT_SUPPORTED The same code runs just fine with version 2015.1. Can anybody else confirm that issue and are there any thoughts where that error might originate from? Thanks very much for any help!
