How to check cuda version on windows

Other respondents have already described which commands can be used to check the CUDA version. Here, I’ll describe how to turn the output of those commands into an environment variable of the form «10.2», «11.0», etc.

To recap, you can use

nvcc --version

to find out the CUDA version.
I think this should be your first port of call.
If you have multiple versions of CUDA installed, this command should print out the version for the copy which is highest on your PATH.

The output looks like this:

nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2020 NVIDIA Corporation
Built on Thu_Jun_11_22:26:38_PDT_2020
Cuda compilation tools, release 11.0, V11.0.194
Build cuda_11.0_bu.TC445_37.28540450_0

We can pass this output through sed to pick out just the MAJOR.MINOR release version number.

CUDA_VERSION=$(nvcc --version | sed -n 's/^.*release ([0-9]+.[0-9]+).*$/1/p')

If nvcc isn’t on your path, you should be able to run it by specifying the full path to the default location of nvcc instead.

/usr/local/cuda/bin/nvcc --version

The output of which is the same as above, and it can be parsed in the same way.

Alternatively, you can find the CUDA version from the version.txt file.

cat /usr/local/cuda/version.txt

The output of which

CUDA Version 10.1.243

can be parsed using sed to pick out just the MAJOR.MINOR release version number.

CUDA_VERSION=$(cat /usr/local/cuda/version.txt | sed 's/.* ([0-9]+.[0-9]+).*/1/')

Note that sometimes the version.txt file refers to a different CUDA installation than the nvcc --version. In this scenario, the nvcc version should be the version you’re actually using.

We can combine these three methods together in order to robustly get the CUDA version as follows:

if nvcc --version 2&> /dev/null; then
    # Determine CUDA version using default nvcc binary
    CUDA_VERSION=$(nvcc --version | sed -n 's/^.*release ([0-9]+.[0-9]+).*$/1/p');

elif /usr/local/cuda/bin/nvcc --version 2&> /dev/null; then
    # Determine CUDA version using /usr/local/cuda/bin/nvcc binary
    CUDA_VERSION=$(/usr/local/cuda/bin/nvcc --version | sed -n 's/^.*release ([0-9]+.[0-9]+).*$/1/p');

elif [ -f "/usr/local/cuda/version.txt" ]; then
    # Determine CUDA version using /usr/local/cuda/version.txt file
    CUDA_VERSION=$(cat /usr/local/cuda/version.txt | sed 's/.* ([0-9]+.[0-9]+).*/1/')

else
    CUDA_VERSION=""

fi

This environment variable is useful for downstream installations, such as when pip installing a copy of pytorch that was compiled for the correct CUDA version.

python -m pip install 
    "torch==1.9.0+cu${CUDA_VERSION/./}" 
    "torchvision==0.10.0+cu${CUDA_VERSION/./}" 
    -f https://download.pytorch.org/whl/torch_stable.html

Similarly, you could install the CPU version of pytorch when CUDA is not installed.

if [ "$CUDA_VERSION" = "" ]; then
    MOD="+cpu";
    echo "Warning: Installing CPU-only version of pytorch"
else
    MOD="+cu${CUDA_VERSION/./}";
    echo "Installing pytorch with $MOD"
fi

python -m pip install 
    "torch==1.9.0${MOD}" 
    "torchvision==0.10.0${MOD}" 
    -f https://download.pytorch.org/whl/torch_stable.html

But be careful with this because you can accidentally install a CPU-only version when you meant to have GPU support.
For example, if you run the install script on a server’s login node which doesn’t have GPUs and your jobs will be deployed onto nodes which do have GPUs. In this case, the login node will typically not have CUDA installed.

Here you will learn how to check NVIDIA CUDA version in 3 ways: nvcc from CUDA toolkit, nvidia-smi from NVIDIA driver, and simply checking a file. Using one of these methods, you will be able to see the CUDA version regardless the software you are using, such as PyTorch, TensorFlow, conda (Miniconda/Anaconda) or inside docker.

Prerequisite

You should have NVIDIA driver installed on your system, as well as Nvidia CUDA toolkit, aka, CUDA, before we start. If you haven’t, you can install it by running sudo apt install nvidia-cuda-toolkit.

What is CUDA?

CUDA is a general parallel computing architecture and programming model developed by NVIDIA for its graphics cards (GPUs). Using CUDA, PyTorch or TensorFlow developers will dramatically increase the performance of PyTorch or TensorFlow training models, utilizing GPU resources effectively.

In GPU-accelerated technology, the sequential portion of the task runs on the CPU for optimized single-threaded performance, while the computed-intensive segment, like PyTorch technology, runs parallel via CUDA at thousands of GPU cores. When using CUDA, developers can write a few basic keywords in common languages such as C, C++ , Python, and implement parallelism.

Method 1 — Use nvcc to check CUDA version

If you have installed the cuda-toolkit software either from the official Ubuntu repositories via sudo apt install nvidia-cuda-toolkit, or by downloading and installing it manually from the official NVIDIA website, you will have nvcc in your path (try echo $PATH) and its location will be /usr/bin/nvcc (by running which nvcc).

To check CUDA version with nvcc, run

nvcc --version

You can see similar output in the screenshot below. The last line shows you version of CUDA. The version here is 10.1. Yours may vary, and can be either 10.0, 10.1, 10.2 or even older versions such as 9.0, 9.1 and 9.2. After the screenshot you will find the full text output too.

vh@varhowto-com:~$ nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2019 NVIDIA Corporation
Built on Sun_Jul_28_19:07:16_PDT_2019
Cuda compilation tools, release 10.1, V10.1.243

What is nvcc?

nvcc is the NVIDIA CUDA Compiler, thus the name. It is the key wrapper for the CUDA compiler suite. For other usage of nvcc, you can use it to compile and link both host and GPU code.

Check out nvcc‘s manpage for more information.

Method 2 — Check CUDA version by nvidia-smi from NVIDIA Linux driver

The second way to check CUDA version is to run nvidia-smi, which comes from downloading the NVIDIA driver, specifically the NVIDIA-utils package. You can install either Nvidia driver from the official repositories of Ubuntu, or from the NVIDIA website.

$ which nvidia-smi
/usr/bin/nvidia-smi
$ dpkg -S /usr/bin/nvidia-smi
nvidia-utils-440: /usr/bin/nvidia-smi

To check CUDA version with nvidia-smi, directly run

nvidia-smi

You can see similar output in the screenshot below. The version is at the top right of the output. Here’s my version is CUDA 10.2. You may have 10.0, 10.1 or even the older version 9.0 or 9.1 or 9.2 installed.

Importantly, except for CUDA version. There are more details in the nvidia-smi output, driver version (440.100), GPU name, GPU fan percentage, power consumption/capability, memory usage, can also be found here. You can also find the processes which use the GPU at the moment. This is helpful if you want to see if your model or system is using GPU such as PyTorch or TensorFlow.

Here is the full text output:

What is nvidia-smi?

nvidia-smi (NVSMI) is NVIDIA System Management Interface program. It is also known as NVSMI. nvidia-smi provides monitoring and maintenance capabilities for all of tje Fermi’s Tesla, Quadro, GRID and GeForce NVIDIA GPUs and higher architecture families. For most functions, GeForce Titan Series products are supported with only little detail given for the rest of the Geforce range.

NVSMI is also a cross-platform application that supports both common NVIDIA driver-supported Linux distros and 64-bit versions of Windows starting with Windows Server 2008 R2. Metrics may be used directly by users via stdout, or stored via CSV and XML formats for scripting purposes.

For more information, check out the man page of nvidia-smi.

Method 3 — cat /usr/local/cuda/version.txt

cat /usr/local/cuda/version.txt

Note that if you install Nvidia driver and CUDA from Ubuntu 20.04’s own official repository this approach may not work.

как указывает Даниэль, deviceQuery является образцом SDK приложение, которое запрашивает выше, наряду с возможностями устройства.

как отмечают другие, вы также можете проверить содержание version.txt использование (например, на Mac или Linux)

иногда папка называется «Cuda-version».

результат должен быть похож на: CUDA Version 8.0.61

Если вы установили CUDA SDK, вы можете запустить «deviceQuery», чтобы увидеть версию CUDA

вы можете найти CUDA-Z полезным, вот цитата с их сайта:

» эта программа родилась как пародия на другие Z-утилиты, такие как CPU-Z и GPU-Z. CUDA-Z показывает некоторую базовую информацию о графических процессорах с поддержкой CUDA и GPGPUs. Он работает с картами nVIDIA Geforce, Quadro и Tesla, ионными чипсетами.»

на вкладке поддержка есть URL для исходного кода: http://sourceforge.net/p/cuda-z/code/ и загрузка на самом деле не является установщиком, а исполняемым файлом (без установки, поэтому это «быстро»).

эта утилита предоставляет множество информации, и если вам нужно знать, как она была получена, есть источник посмотреть. Есть другие утилиты, похожие на это, которые вы можете искать.

после установки CUDA можно проверить версии по: nvcc-V

Я установил как 5.0, так и 5.5, поэтому он дает

Check cuda version windows

The installation instructions for the CUDA Toolkit on MS-Windows systems.

1. Introduction

CUDA В® is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).

This guide will show you how to install and check the correct operation of the CUDA development tools.

1.1. System Requirements

The next two tables list the currently supported Windows operating systems and compilers.

Table 1. Windows Operating System Support in CUDA 11.4

Table 2. Windows Compiler Support in CUDA 11.4

* Support for Visual Studio 2015 is deprecated in release 11.1.

x86_32 support is limited. See the x86 32-bit Support section for details.

For more information on MSVC versions, Visual Studio product versions, visit https://dev.to/yumetodo/list-of-mscver-and-mscfullver-8nd.

1.2. x86 32-bit Support

Native development using the CUDA Toolkit on x86_32 is unsupported. Deployment and execution of CUDA applications on x86_32 is still supported, but is limited to use with GeForce GPUs. To create 32-bit CUDA applications, use the cross-development capabilities of the CUDA Toolkit on x86_64.

1.3. About This Document

This document is intended for readers familiar with Microsoft Windows operating systems and the Microsoft Visual Studio environment. You do not need previous experience with CUDA or experience with parallel computation.

Basic instructions can be found in the Quick Start Guide. Read on for more detailed instructions.

2.1. Verify You Have a CUDA-Capable GPU

You can verify that you have a CUDA-capable GPU through the Display Adapters section in the Windows Device Manager. Here you will find the vendor name and model of your graphics card(s). If you have an NVIDIA card that is listed in http://developer.nvidia.com/cuda-gpus, that GPU is CUDA-capable. The Release Notes for the CUDA Toolkit also contain a list of supported products.

2.2. Download the NVIDIA CUDA Toolkit

The CUDA Toolkit installs the CUDA driver and tools needed to create, build and run a CUDA application as well as libraries, header files, CUDA samples source code, and other resources.

Download Verification

The download can be verified by comparing the MD5 checksum posted at https://developer.download.nvidia.com/compute/cuda/11.4.2/docs/sidebar/md5sum.txt with that of the downloaded file. If either of the checksums differ, the downloaded file is corrupt and needs to be downloaded again.

To calculate the MD5 checksum of the downloaded file, follow the instructions at http://support.microsoft.com/kb/889768.

2.3. Install the CUDA Software

Graphical Installation

Install the CUDA Software by executing the CUDA installer and following the on-screen prompts.

Note: C:ProgramData is a hidden folder. It can be made visible within the Windows Explorer options at (Tools | Options).

Driver Subpackages Display.Driver The NVIDIA Display Driver. Required to run CUDA applications.

Extracting and Inspecting the Files Manually

Sometimes it may be desirable to extract or inspect the installable files directly, such as in enterprise deployment, or to browse the files before installation. The full installation package can be extracted using a decompression tool which supports the LZMA compression method, such as 7-zip or WinZip.

2.3.1. Uninstalling the CUDA Software

All subpackages can be uninstalled through the Windows Control Panel by using the Programs and Features widget.

2.4. Using Conda to Install the CUDA Software

This section describes the installation and configuration of CUDA when using the Conda installer. The Conda packages are available at https://anaconda.org/nvidia.

2.4.1. Conda Overview

2.4.2. Installation

To perform a basic install of all CUDA Toolkit components using Conda, run the following command:

2.4.3. Uninstallation

To uninstall the CUDA Toolkit using Conda, run the following command:

2.5. Use a Suitable Driver Model

On Windows 7 and later, the operating system provides two under which the NVIDIA Driver may operate:

The TCC driver mode provides a number of advantages for CUDA applications on GPUs that support this mode. For example:

2.6. Verify the Installation

Before continuing, it is important to verify that the CUDA toolkit can find and communicate correctly with the CUDA-capable hardware. To do this, you need to compile and run some of the included sample programs.

2.6.1. Running the Compiled Examples

Start > All Programs > Accessories > Command Prompt

This assumes that you used the default installation directory structure. If CUDA is installed and configured correctly, the output should look similar to Figure 1.

The exact appearance and the output lines might be different on your system. The important outcomes are that a device was found, that the device(s) match what is installed in your system, and that the test passed.

If a CUDA-capable device and the CUDA Driver are installed but deviceQuery reports that no CUDA-capable devices are present, ensure the deivce and driver are properly installed.

Running the bandwidthTest program, located in the same directory as deviceQuery above, ensures that the system and the CUDA-capable device are able to communicate correctly. The output should resemble Figure 2.

The device name (second line) and the bandwidth numbers vary from system to system. The important items are the second line, which confirms a CUDA device was found, and the second-to-last line, which confirms that all necessary tests passed.

If the tests do not pass, make sure you do have a CUDA-capable NVIDIA GPU on your system and make sure it is properly installed.

3. Pip Wheels

NVIDIA provides Python Wheels for installing CUDA through pip, primarily for using CUDA with Python. These packages are intended for runtime use and do not currently include developer tools (these can be installed separately).

Please note that with this installation method, CUDA installation environment is managed via pip and additional care must be taken to set up your host environment to use CUDA outside the pip environment.

4. Compiling CUDA Programs

4.1. Compiling Sample Projects

The bandwidthTest project is a good sample project to build and run. It is located in the NVIDIA CorporationCUDA Samplesv 11.4 1_UtilitiesbandwidthTest directory.

4.2. Sample Projects

The sample projects come in two configurations: debug and release (where release contains no debugging information) and different Visual Studio projects.

A few of the example projects require some additional setup.

4.3. Build Customizations for New Projects

When creating a new CUDA application, the Visual Studio project file must be configured to include CUDA build customizations. To accomplish this, click File-> New | Project. NVIDIA-> CUDA->, then select a template for your CUDA Toolkit version. For example, selecting the «CUDA 11.4 Runtime» template will configure your project for use with the CUDA 11.4 Toolkit. The new project is technically a C++ project (.vcxproj) that is preconfigured to use NVIDIA’s Build Customizations. All standard capabilities of Visual Studio C++ projects will be available.

To specify a custom CUDA Toolkit location, under CUDA C/C++, select Common, and set the CUDA Toolkit Custom Dir field as desired. Note that the selected toolkit must match the version of the Build Customizations.

4.4. Build Customizations for Existing Projects

While Option 2 will allow your project to automatically use any new CUDA Toolkit version you may install in the future, selecting the toolkit version explicitly as in Option 1 is often better in practice, because if there are new CUDA configuration options added to the build customization rules accompanying the newer toolkit, you would not see those new options using Option 2.

5. Additional Considerations

A number of helpful development tools are included in the CUDA Toolkit or are available for download from the NVIDIA Developer Zone to assist you as you develop your CUDA programs, such as NVIDIA В® Nsightв„ў Visual Studio Edition, NVIDIA Visual Profiler, and cuda-memcheck.

For technical support on programming questions, consult and participate in the developer forums at http://developer.nvidia.com/cuda/.

In this chapter, we will learn how to install CUDA.

For installing the CUDA toolkit on Windows, you’ll need −

• A CUDA enabled Nvidia GPU.
• A supported version of Microsoft Windows.
• A supported version of Visual Studio.
• The latest CUDA toolkit.

Note that natively, CUDA allows only 64b applications. That is, you cannot develop 32b CUDA applications natively (exception: they can be developed only on the GeForce series GPUs). 32b applications can be developed on x86_64 using the cross-development capabilities of the CUDA toolkit. For compiling CUDA programs to 32b, follow these steps −

Step 1 − Add <installpath>bin to your path.

Step 2 − Add -m32 to your nvcc options.

Step 3 − Link with the 32-bit libs in <installpath>lib (instead of <installpath>lib64).

You can download the latest CUDA toolkit from here.

Compatibility

As can be seen from the above tables, support for x86_32 is limited. Presently, only the GeForce series is supported for 32b CUDA applications. If you have a supported version of Windows and Visual Studio, then proceed. Otherwise, first install the required software.

Verifying if your system has a CUDA capable GPU − Open a RUN window and run the command − control /name Microsoft.DeviceManager, and verify from the given information. If you do not have a CUDA capable GPU, or a GPU, then halt.

Installing the Latest CUDA Toolkit

In this section, we will see how to install the latest CUDA toolkit.

Step 1 − Visit − https://developer.nvidia.com and select the desired operating system.

Step 2 − Select the type of installation that you would like to perform. The network installer will initially be a very small executable, which will download the required files when run. The standalone installer will download each required file at once and won’t require an Internet connection later to install.

Step 3 − Download the base installer.

The CUDA toolkit will also install the required GPU drivers, along with the required libraries and header files to develop CUDA applications. It will also install some sample code to help starters. If you run the executable by double-clicking on it, just follow the on-screen directions and the toolkit will be installed. This is the graphical way of installation, and the downside of this method is that you do not have control on what packages to install. This can be avoided if you install the toolkit using CLI. Here is a list of possible packages that you can control −

For example, to install only the compiler and the occupancy calculator, use the following command −

<PackageName>.exe -s nvcc_9.1 occupancy_calculator_9.1

Verifying the Installation

Follow these steps to verify the installation −

Step 1 − Check the CUDA toolkit version by typing nvcc -V in the command prompt.

Step 2 − Run deviceQuery.cu located at: C:ProgramDataNVIDIA CorporationCUDA Samplesv9.1binwin64Release to view your GPU card information. The output will look like −

Step 3 − Run the bandWidth test located at C:ProgramDataNVIDIA CorporationCUDA Samplesv9.1binwin64Release. This ensures that the host and the device are able to communicate properly with each other. The output will look like −

If any of the above tests fail, it means the toolkit has not been installed properly. Re-install by following the above instructions.

Uninstalling

CUDA can be uninstalled without any fuss from the ‘Control Panel’ of Windows.

At this point, the CUDA toolkit is installed. You can get started by running the sample programs provided in the toolkit.

Setting-up Visual Studio for CUDA

For doing development work using CUDA on Visual Studio, it needs to be configured. To do this, go to − File → New | Project… NVIDIA → CUDA →. Now, select a template for your CUDA Toolkit version (We are using 9.1 in this tutorial). To specify a custom CUDA Toolkit location, under CUDA C/C++, select Common, and set the CUDA Toolkit Custom Directory.
