CUDA is not available on macOS from version 11 and up #100

Closed blueberry closed 3 years ago

blueberry commented 3 years ago

Stack trace from the attempt to load the library as a resource:

java.io.IOException: No resource found with name '/lib/libJCudaRuntime-11.0.0-apple-x86_64.dylib'
etc.

This is not a bug. CUDA is not available on macOS any more, due to Apple/Nvidia hostility.

The solution is to explicitly exclude all dependencies related to CUDA.

For example, add something like this in your project.clj to globally exclude JCuda jars:

:exclusions [org.jcuda/jcuda
                    org.jcuda/jcublas]

Please see the updated hello world project.clj. These exclusions have to be added:

:exclusions [[org.jcuda/jcuda-natives :classifier "apple-x86_64"]
            [org.jcuda/jcublas-natives :classifier "apple-x86_64"]]

On Mac with M1 Arm chip you have to leave out the classifier or change the classifier to "linux-aarch64" otherwise it will complain on not finding these packages at first repl start.
