Select your preferences and run the install command. Stable represents the most currently tested and supported version of PyTorch. This should be suitable for many users. Preview is available if you want the latest, not fully tested and supported, 1.7 builds that are generated nightly. Note: We've detected that Torch Browser's installer might attempt to bundle third-party software. Our team has compiled a list of clean alternatives you can try instead.
We have outsourced a lot of functionality of PyTorch Geometric to other packages, which needs to be additionally installed.These packages come with their own CPU and GPU kernel implementations based on C++/CUDA extensions.
Note
We do not recommend installation as root user on your system python.Please setup an Anaconda/Miniconda environment or create a Docker image.
Please follow the steps below for a successful installation.
Installation via Binaries¶
We provide pip wheels for all major OS/PyTorch/CUDA combinations:
- Ensure that at least PyTorch 1.4.0 is installed:
- Find the CUDA version PyTorch was installed with:
- Install the relevant packages:where
${CUDA}
and${TORCH}
should be replaced by your specific CUDA version (cpu
,cu92
,cu101
,cu102
) and PyTorch version (1.4.0
,1.5.0
,1.6.0
), respectively.For example, for PyTorch 1.5.0/1.5.1 and CUDA 10.2, type:For PyTorch 1.6.0 and CUDA 10.1, type:
Installation from Source¶
In case a specific version is not supported by our wheels, you can alternatively install PyTorch Geometric from source:
- Ensure that your CUDA is setup correctly (optional):
- Check if PyTorch is installed with CUDA support:
- Add CUDA to
$PATH
and$CPATH
(note that your actual CUDA path may vary from/usr/local/cuda
): - Add CUDA to
$LD_LIBRARY_PATH
on Linux and to$DYLD_LIBRARY_PATH
on macOS (note that your actual CUDA path may vary from/usr/local/cuda
): - Verify that
nvcc
is accessible from terminal: - Ensure that PyTorch and system CUDA versions match:
- Install all needed packages:
In rare cases, CUDA or Python path problems can prevent a successful installation.
pip
may even signal a successful installation, but runtime errors complain about missing modules, .e.g., Nomodulenamed'torch_*.*_cuda'
, or execution simply crashes with Segmentationfault(coredumped)
.We collected a lot of common installation errors in the Frequently Asked Questions subsection.In case the FAQ does not help you in solving your problem, please create an issue.You should additionally verify that your CUDA is set up correctly by following the official installation guide, and that the official extension example runs on your machine.Frequently Asked Questions¶

For installation, first, you have to choose your preference and then run the install command. You can start installation locally or with a cloud partner. In the below diagram, Stable shows the most currently supported and tested version of PyTorch (1.1), which is suitable for many users. If you want the latest 1.1 builds but not fully tested and supported, then you have to choose Preview (Nightly).
For installation, it's necessary that you have met the prerequisites which are suited to your package manager. We recommend you to use Anaconda package manager because it installs all the dependencies.
Platforms, Os, Language and other prerequisites | |||||

Installation on Linux
PyTorch installation in Linux is similar to the installation of Windows using Conda. To install PyTorch in your Linux system, you have to follow the steps which are giving below.
Step 1:
Your first step is to download Anaconda in your Linux operating system. To download it, you have to go through the following link https://www.anaconda.com/distribution/.
Step 2:
Here, you choose the latest version of python, i.e., 3.7 and click right button of the mouse and copy link address to install it.
Step 3:
Open your terminal and run the copy link on the terminal using wget <link> command. This command download Anaconda in your Linux system.
It takes a few seconds to download. Once downloading is complete your cursor go back to your home directory.
Step 4:
Next step is to install Anaconda in your system. To install it, you have to first enter in downloads directory or where you have downloaded your anaconda. Installation is done with bash file because in Linux when you download Anaconda, It downloaded as bash file. So, to install Anaconda, you have to run the bash ~/Downloads/Anaconda3-2019.03-Linux-x86_64.sh command for the latest version of python 3.7 or to run the bash ~/Downloads/Anaconda2-2019.03-Linux-x86_64.sh command for python 2.7.
Here, you have to press the enter button to continue. When you press enter your installation is started. After a few installations it asks you one more question, i.e., Do you accept the license terms? You give it an answer by typing, yes.
