Understanding PyTorch Versions
- PyTorch versioning scheme
- PyTorch uses a semantic versioning scheme, where each release is assigned a version number in the format of MAJOR.MINOR.PATCH. This format is designed to provide information about the significance of each release.
- The major version number is incremented when there are significant changes that may break backward compatibility.
- The minor version number is incremented when new features are added, but backward compatibility is maintained.
- The patch version number is incremented for bug fixes and maintenance releases.
- Significance of major, minor, and patch versions
- Major versions
- Major releases represent significant changes to the framework that may require changes to code written using previous versions. These changes can include the addition or removal of features, improvements to performance, or changes to the API.
- Minor versions
- Minor releases introduce new features, improvements, or enhancements that are backward compatible with the previous version. This means that code written for a previous minor version should still work with the latest minor version, although there may be some additional features or improvements available.
- Patch versions
- Patch releases are typically bug fixes and maintenance releases. These releases do not introduce new features or enhancements, but instead focus on improving stability and fixing issues. Patch releases are always backward compatible with the previous version.
