How to Install PyTorch with CUDA in setup.py
If you’re a data scientist or software engineer working with deep learning, chances are you’re familiar with PyTorch. PyTorch is a popular open-source machine learning framework that’s widely used for developing deep learning models. One of the biggest advantages of PyTorch is that it provides support for NVIDIA CUDA, a parallel computing platform that enables GPU acceleration for deep learning tasks. In this article, we’ll walk you through the process of installing PyTorch with CUDA in setup.py.

Why Install PyTorch with CUDA?
Before we dive into the installation process, let’s first take a look at why you might want to install PyTorch with CUDA. GPUs are highly parallel devices that can perform a large number of calculations simultaneously. This makes them ideal for accelerating deep learning tasks, which often involve large amounts of matrix operations. PyTorch provides support for CUDA, which allows you to harness the power of GPUs and significantly speed up your model’s training and inference times.
Before we get started with the installation process, make sure you have the following prerequisites installed:
- Python 3.x
- CUDA-enabled GPU
- NVIDIA CUDA Toolkit (version 10.2 or later)
- NVIDIA cuDNN library (version 7.6.5 or later)
Step-by-step installing Pytorch with CUDA in setup.py
Step 1: Create a virtual environment
It’s always a good idea to create a virtual environment before installing any new packages. This ensures that any changes made to your system won’t affect other projects that you’re working on. To create a new virtual environment, run the following command:
$ python3 -m venv myenv
This will create a new virtual environment named
Step 2: Activate the virtual environment
Next, activate the virtual environment by running the following command:
$ source myenv/bin/activate
This will activate the
myenv virtual environment.
Step 3: Install PyTorch with CUDA
Now that we have our virtual environment set up, we can install PyTorch with CUDA. To do this, we’ll use
pip. Run the following command to install PyTorch with CUDA:
$ pip install torch torchvision torchaudio -f https://download.pytorch.org/whl/cu111/torch_stable.html
This will install the latest version of PyTorch with CUDA support.
Step 4: Update setup.py
To ensure that PyTorch with CUDA is included as a dependency when someone installs your package, you need to update your
setup.py file. Open your
setup.py file and add the following line to the
This will ensure that PyTorch with CUDA is installed when someone installs your package using
Step 5: Build and install your package
Finally, you can build and install your package as you normally would. Run the following command to build your package:
$ python setup.py sdist bdist_wheel
This will create a source distribution and a wheel distribution of your package.
To install your package, run the following command:
$ pip install dist/<package-name>-<version>.tar.gz
<version> with the name and version of your package.
Pros and Cons of Using setup.py for Installation
Customization: setup.py allows for fine-grained control over the installation process, enabling you to configure CUDA-specific settings.
Integration: It seamlessly integrates with existing Python packaging tools and workflows.
Complexity: Modifying setup.py may be intimidating for beginners, and incorrect configurations can lead to installation failures.
Dependency Management: Ensuring that users have the correct CUDA toolkit version and dependencies can be challenging.
Common Errors and Troubleshooting
CUDA Compatibility Issues
Ensure that your GPU is CUDA-compatible and that you have the correct version of the CUDA Toolkit installed.
Check for missing dependencies such as cuDNN and ensure they are installed and configured correctly.
Verifying the Installation
After installation, verify that PyTorch is utilizing CUDA by running a simple GPU-enabled script.
In this article, we’ve walked you through the process of installing PyTorch with CUDA in setup.py. By following these steps, you can ensure that your package includes PyTorch with CUDA as a dependency and takes full advantage of the power of GPUs for deep learning tasks. Happy coding!
