numba.cuda.cudadrv.error.CudaSupportError：驱动程序初始化时出错：，Quadro M2000，运行 Ubuntu 20.04

Question

我正在运行 Ubuntu 20.04，并有一张 Quadro M2000 卡，运行$ nvidia-smi -L后，

GPU 0: Quadro M2000 (UUID: GPU-df3aa58b-eac2-2d70-3e96-8915f899997e)

我想将它用于 python，因此我numba使用进行了安装$ pip install numba，检查nvcc -v哪个要求我安装它。

安装时，我收到以下错误：

$ sudo apt install nvidia-cuda-toolkit
Reading package lists... Done

Some packages could not be installed. This may mean that you have

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 nvidia-cuda-toolkit : Depends: nvidia-profiler (= 10.1.243-3) but it is not going to be installed
                       Depends: nvidia-cuda-dev (= 10.1.243-3) but it is not going to be installed

                       Recommends: nsight-systems (= 10.1.243-3)
E: Unable to correct problems, you have held broken packages

我安装的驱动程序是 390 号（从 nvidia 网站上查找 M2000 驱动程序）我尝试手动安装其中几个包，但没有成功。

因此，我重新按照步骤操作NVIDIA CUDA 下载安装cuda。

之后我决定检查一下numba，

>>> import numba
>>> numba.__version__
'0.56.2'

好的，numba安装正确，

>>> from numba import cuda
>>> print(cuda.gpus)
```Traceback (most recent call last):

Call to cuInit results in UNKNOWN_CUDA_ERROR (803):

我怎样才能解决这个问题？
