{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"OpenCL interoperability does not work on CUDA machine","articleBody":"On (Linux) CUDA machine, the backend returned by `af.get_backend()` remains at unified even if the backend is correctly set as OpenCL. `af.get_active_backend()` correctly returns OpenCL as the backend, but since the interoperability functions use different way to check the backend, an error is output (see https://github.com/arrayfire/arrayfire-python/blob/master/arrayfire/opencl.py#L107). Commenting all those instances fixes the issue. The (commented) tests reproduce this error, i.e. https://github.com/arrayfire/arrayfire-python/blob/master/tests/simple/interop.py#L82\r\n\r\nNote that this wasn't an issue on a (Windows) AMD machine, where OpenCL is the default backend.","author":{"url":"https://github.com/villekf","@type":"Person","name":"villekf"},"datePublished":"2024-04-22T08:33:42.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/267/arrayfire-python/issues/267"}
