How to downgrade to cuda 10.0 in arch linux?

I want to downgrade my cuda 10.1 to cuda 10.0 in arch linux as tensorflow requires cuda 10.0 only.

I installed tensorflow on CUDA 10.1 in arch Linux but I didn't know tensorflow-gpu needs CUDA 10.0 or lesser.

I tried tried symlinking the required 10.0 libraries with new 10.1 libraries but it didn't work.

Whenever I try to import tensorflow in python console error shows up that 'libcublas.so.10.0' not found.

So I found out that I can only run tensorflow on CUDA 10.0 so now I want to downgrade my CUDA. But I have no Idea how to do that in arch Linux.

Every time I run import tensorflow it gives this error.

Failed to load the native TensorFlow runtime.

pacman -S cuda=="10.0" is not working.

I searched everywhere but couldn't find any proper answer for arch Linux to downgrade to CUDA 10.0

回答1:

Download cuda 10.0 package from here: http://archlinux.arkena.net/archive/packages/c/cuda/cuda-10.0.130-2-x86_64.pkg.tar.xz
Install package sudo pacman -U cuda-10.0.130-2-x86_64.pkg.tar.xz

I'm facing the same issue and have to re-apply the method I used when I was using my old gtx670:
