A good catch, I admit that I didn’t experiment with the CUDA stuff when I posted it. It seems that instead of refreshing the page via “Ctrl-R”, you’ll have to manually reload the kernel via
- go to “view resources” → “change runtime type”
- ensure it is “Julia” and “GPU”. Almost certainly you don’t need to change anything here if you’re already on GPU runtime.
- click “save” to trigger the kernel reload.
FWIW, I uploaded a new julia_cuda.ipynb
file to smooth this progress.
