Ich verwende Ubuntu 20.04 und habe eine Quadro M2000-Karte $ nvidia-smi -L.
GPU 0: Quadro M2000 (UUID: GPU-df3aa58b-eac2-2d70-3e96-8915f899997e)
Ich wollte es für Python verwenden und habe es daher numbamit $ pip install numba„Checked“ installiert, nvcc -vworaufhin ich aufgefordert wurde, es zu installieren.
Während der Installation erhalte ich die folgenden Fehlermeldungen:
$ sudo apt install nvidia-cuda-toolkit

Die Treiber, die ich installiert habe, sind die 390er (auf der Nvidia-Website nach M2000-Treibern gesucht). Ich habe versucht, einige dieser Pakete manuell zu installieren, aber das hat nicht geklappt.
Also habe ich die Schritte noch einmal befolgtNVIDIA CUDA herunterladenum cuda zu installieren.
Im Anschluss daran beschloss ich zu prüfen numba,
>>> import numba
>>> numba.__version__
'0.56.2'
Ok, also numbarichtig installiert,
>>> from numba import cuda
>>> print(cuda.gpus)

Wie kann ich hoffen, das zu klären?
