If you’re like me, you’re always trying to stay up-to-date with the latest and greatest Pytorch releases. But sometimes it can be hard to know which version you need for your project.
Here’s a quick and easy guide on how to get the Pytorch version you need.

Why you may need a specific Pytorch version
Depending on your development environment, you may need a specific version of Pytorch. For example, if you are developing on MacOS and using Xcode, the default Pytorch version installed via pip may not work. In this case, you will need to install a specific Pytorch version that is compatible with your Xcode version.
To find out which Pytorch versions are compatible with your Xcode version, you can check thegithub page for each release. For example, for Xcode 11.4.1, the supported Pytorch versions are 1.4.0 and 1.5.0-rc1.
You can also check the release notes for each Pytorch version to see which versions of Xcode aresupported. For example, for Pytorch 1.4.0, the supported Xcode versions are 11.2, 11.3 and 11.4.1
How to check if you have the right Pytorch version
If you installed Pytorch from PyPI, you can check the version by running the following command:
python -c “import torch; print(torch.__version__)”
How to install a specific Pytorch version
Whether you’re rolling out a new machine learning model or trying to reproduce results from a paper, it’s important to be able to install the right version of Pytorch. Here’s a guide on how to do that.
First, go to the Pytorch releases page and find the version you need.
Next, go to your command line and type:
pip install torch==[version]
For example, if you wanted to install Pytorch 0.4.1, you would type:
pip install torch==0.4.1
And that’s it! You now have the specific Pytorch version you need.
How to uninstall Pytorch
If you have multiple versions of Pytorch installed on your system, you can use the pip3 uninstall command to remove the one you don’t need.
How to update Pytorch to the latest version
If you’re using Pytorch in your machine learning projects, it’s important to keep it up to date. Newer versions of Pytorch offer performance improvements and bug fixes that can make a big difference in your results. Here’s how to update Pytorch to the latest version.
First, make sure you have the newest version of pip installed:
pip install – upgrade pip
Next, check the current version of Pytorch installed on your system:
pip show torch
If necessary, update Pytorch with the following command:
pip install torch – upgrade
How to use Pytorch with virtual environments
Pytorch is a great tool for machine learning, but can be tricky to install. The good news is that you can use Pytorch with virtual environments to manage your installation and keep your system clean.
Virtual environments are like mini versions of your operating system that can run their own python installation. This means you can have multiple versions of Pytorch installed on your system without them interfering with each other.
To use Pytorch with a virtual environment, you first need to create the environment. I like to use the virtualenvwrappers tool to manage my virtual environments, but you can use any tool you like.
Once you have your virtual environment set up, you can then install Pytorch into it using pip. Make sure you use the correct version of pip for your virtual environment. For example, if you are using virtualenvwrappers, you would use the ‘-p’ option when creating your environment to specify the correct pip version.
Once Pytorch is installed in your virtual environment, you can then activate the environment and start using Pytorch. To deactivate the environment, simply type ‘deactivate’ at the command prompt.
