如何从命令行获得 nvidia 驱动程序版本？

为了调试 CUDA 代码和检查兼容性，我需要找出我安装的 GPU 的 nvidia 驱动程序版本。我找到了 如何得到可达的版本？，但这对我没有帮助。

If you use:

me@over_there:~$  dpkg --status nvidia-current | grep Version | cut -f 1 -d '-' | sed 's/[^.,0-9]//g'
260.19.06

you will get the version of the nVIDIA driver package installed through your distribution's packaging mechanism. But this may not be the version that is actually running as part of your kernel right now.

Using nvidia-smi should tell you that:

bwood@mybox:~$ nvidia-smi

On any linux system with the NVIDIA driver installed and loaded into the kernel, you can execute:

cat /proc/driver/nvidia/version

to get the version of the currently loaded NVIDIA kernel module, for example:

$ cat /proc/driver/nvidia/version
NVRM version: NVIDIA UNIX x86_64 Kernel Module  304.54  Sat Sep 29 00:05:49 PDT 2012
GCC version:  gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)

modinfo does the trick.

root@nyx:/usr/src# modinfo nvidia|grep version:
version:        331.113

Windows version:

cd \Program Files\NVIDIA Corporation\NVSMI

nvidia-smi

If you need to get that in a program with Python on a Linux system for reproducibility:

with open('/proc/driver/nvidia/version') as f:
version = f.read().strip()
print(version)

gives:

NVRM version: NVIDIA UNIX x86_64 Kernel Module  384.90  Tue Sep 19 19:17:35 PDT 2017
GCC version:  gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5)

To expand on ccc's answer, if you want to incorporate querying the card with a script, here is information on Nvidia site on how to do so:

https://nvidia.custhelp.com/app/answers/detail/a_id/3751/~/useful-nvidia-smi-queries

Also, I found this thread researching powershell. Here is an example command that runs the utility to get the true memory available on the GPU to get you started.

# get gpu metrics
$cmd = "& 'C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi' --query-gpu=name,utilization.memory,driver_version --format=csv"
$gpuinfo = invoke-expression $cmd | ConvertFrom-CSV
$gpuname = $gpuinfo.name
$gpuutil = $gpuinfo.'utilization.memory [%]'.Split(' ')[0]
$gpuDriver = $gpuinfo.driver_version

nvidia-smi --query-gpu=driver_version --format=csv,noheader --id=0

returns result as a string that doesn't require further parsing like: 470.82.00

In case nvidia-smi is not available for some reason, information can be obtained by calling into driver APIs. Driver libraries can be loaded using Python ctypes library.

For CUDA see: https://gist.github.com/f0k/63a664160d016a491b2cbea15913d549

For driver information see: https://github.com/mars-project/mars/blob/a50689cda4376d82a40b7aa9833f572299db7efd/mars/lib/nvutils.py

nvidia-container-cli info is one of the other commands. Below is an example of running my environment.
