I have lately been getting a lot of errors emanating from CUDNN.jl when training Flux models. This happens also with code I really think has or would have worked before.

Does anyone understand this?

It goes on for another 30 000 lines, but even the output above have been heavily edited to keep up the dramatic tension of the narrative.

I think I know now that this behaviour only occurred when I ran `julia` with the `-g 2` option.

That begs the question whether this goes on all the time in working code, just not being reported. In that case I don’t understand the difference between warnings and errors, since none of them appears to be fatal.

Yeah we only show the debug log when running with `-g2` or when `JULIA_DEBUG` includes `cuDNN`: [CUDA.jl/cuDNN.jl at 0dce8ca9022f9c948dd8a7c7bf2f070d8218db05 · JuliaGPU/CUDA.jl · GitHub](https://github.com/JuliaGPU/CUDA.jl/blob/0dce8ca9022f9c948dd8a7c7bf2f070d8218db05/lib/cudnn/src/cuDNN.jl#L169-L179)

Maybe the error gets handled appropriately by the caller, and thus the debug message isn’t a problem. But it’d be good to ensure that’s the case.
