I wonder if the instructions here will help u [I managed to make Flux.jl work with GPUs again!](https://discourse.julialang.org/t/i-managed-to-make-flux-jl-work-with-gpus-again/19386)

You need to install the NVIDIA kernel driver, and/or make sure its `libcuda` is discoverable.

The LD\_LIBRARY\_PATH contains /usr/local/cuda/lib64/stubs To build successfully, I found that this folder must be excluded from the path. Somehow this explains the error message.

Seems pretty clear? No support for CUDA stubs, while you forcibly load modules from `/.../cuda/lib/stubs`…

How did that path end up in your LD\_LIBRARY\_PATH?
