我如何确定完整的CUDA版本+颠覆版本? [英] How can I determine the full CUDA version + subversion?

问题描述

CUDA发行版曾经有一个名为 version.txt 的文件，该文件读取例如:

CUDA distributions on Linux used to have a file named version.txt which read, e.g.:

CUDA Version 10.2.89

这非常有用.但是，从CUDA 11.1开始，此文件不再存在.

which is quite useful. However, as of CUDA 11.1, this file no longer exists.

如何在Linux上和命令行上确定我正在查看哪个版本的/path/to/cuda/toolkit ?包括颠覆吗?

How can I determine, on Linux and from the command line, and inspecting /path/to/cuda/toolkit, which exact version I'm looking at? Including the subversion?

(Answer due to @RobertCrovella's comment)

这可以解决问题:

/path/to/cuda/toolkit/bin/nvcc --version | egrep -o "V[0-9]+.[0-9]+.[0-9]+" | cut -c2-

当然，对于当前选择并配置为使用的CUDA版本，只需采用路径上的 nvcc :

And of course, for the CUDA version currently chosen and configured to be used, just take the nvcc that's on the path:

nvcc --version | egrep -o "V[0-9]+.[0-9]+.[0-9]+" | cut -c2-

例如:您将获得 11.2.67 ，该文件可在本周在NVIDIA网站上下载CUDA 11.2.

For example: You would get 11.2.67 for the download of CUDA 11.2 which was available this week on the NVIDIA website.

完整的 nvcc --version 输出为:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Mon_Nov_30_19:08:53_PST_2020
Cuda compilation tools, release 11.2, V11.2.67
