failed call to cuInit: CUDA_ERROR_UNKNOWN: unknown error

This error message in Bold shows up during 'medaka_consensus':

Running medaka consensus [13:19:50 - Predict] Setting tensorflow inter/intra-op threads to 1/1.

It seems the error does not affect the final result, I still get my consensus.fasta, just wondering why and if it compromise the final quality?

Hi @XW26,

Warnings like this usually result from running medaka on a computer without a GPU device (or at least one one that medaka cannot access). If you do not have a GPU and wish to avoid the warnings you can install the medaka-cpu package from PyPI.

Hi, thank you for the information! However I do have one GPU, and I have installed tensorflow and CUDA toolkit, I can well import tensorflow in python. So probably medaka cannot access GPU, any tips on how to grant access? Many thanks!
