Which Cuda Version Do I Have

How To Articles

As a developer working on CUDA-related projects, knowing which CUDA version I have installed is crucial for ensuring compatibility and optimizing performance. There are several methods to determine the CUDA version on my system, and I’ll cover them in detail below.

Using the nvcc Compiler

One way to find out the CUDA version is by using the nvcc compiler, which is included with the CUDA toolkit. By running the command nvcc --version in my terminal or command prompt, I can easily see the CUDA toolkit version installed on my system.

Checking the CUDA Toolkit Installation Path

Another method I can use is to check the installation path of the CUDA toolkit. The CUDA toolkit is typically installed in a standard location, and examining the directory structure can reveal the version number. For example, on a Linux system, the CUDA toolkit might be installed in /usr/local/cuda-.

Inspecting CUDA Runtime Libraries

Examining the CUDA runtime libraries can also provide information about the installed CUDA version. By locating the CUDA runtime libraries on my system and inspecting their version properties, I can identify the exact version of CUDA that is installed.

Consulting NVIDIA’s Documentation

If I’m still unsure about the CUDA version on my system, I can always refer to NVIDIA’s official documentation or release notes. NVIDIA provides detailed documentation for each CUDA toolkit release, including version numbers, new features, and any known issues. By cross-referencing the information provided in the documentation with my system, I can confirm the installed CUDA version.


Having a clear understanding of the CUDA version installed on my system is essential for managing dependencies and ensuring that my CUDA-accelerated applications run smoothly. By using the methods outlined above, I can confidently determine the CUDA version and proceed with my development tasks.
