Estou rodando o Ubuntu 20.04 e tenho uma placa Quadro M2000, rodando $ nvidia-smi -Ldá,
GPU 0: Quadro M2000 (UUID: GPU-df3aa58b-eac2-2d70-3e96-8915f899997e)
Eu queria usá-lo para python, então instalei numbausando $ pip install numbae verifiquei nvcc -vque me pediu para instalá-lo.
Ao instalá-lo, estou recebendo os seguintes erros:
$ sudo apt install nvidia-cuda-toolkit
Reading package lists... Done

Os drivers que instalei são os 390 (verificados no site da nvidia para drivers M2000). Tentei instalar alguns desses pacotes manualmente, mas não funcionou.
Então, segui novamente os passosBaixar NVIDIA CUDApara instalar o cuda.
Depois disso, decidi verificar numba,
>>> import numba
>>> numba.__version__
'0.56.2'
Ok, então numbafoi instalado corretamente,
>>> from numba import cuda
>>> print(cuda.gpus)
