Bumps sentence-transformers from 5.2.0 to 5.2.2.

Release notes

Sourced from sentence-transformers's releases.

v5.2.2 - Replace mandatory requests dependency with optional httpx dependency

This patch release replaces mandatory requests dependency with an optional httpx dependency.

Install this version with

# Training + Inference
pip install sentence-transformers[train]==5.2.2
Inference only, use one of:
pip install sentence-transformers==5.2.2
pip install sentence-transformers[onnx-gpu]==5.2.2
pip install sentence-transformers[onnx]==5.2.2
pip install sentence-transformers[openvino]==5.2.2

Transformers v5 Support

Transformers v5.0 and its required huggingface_hub versions have dropped support of requests in favor of httpx. The former was also used in sentence-transformers, but not listed explicitly as a dependency. This patch removes the use of requests in favor of httpx, although it's now optional and not automatically imported. This should also save some import time.

Importing Sentence Transformers should now not crash if requests is not installed.

All Changes

• [deps] Replace requests dependency with optional httpx dependency by @​tomaarsen (huggingface/sentence-transformers#3618)

pip install sentence-transformers==5.2.1
pip install sentence-transformers[onnx-gpu]==5.2.1

Transformers v5 Support

Sentence Transformers v5.2.0 already introduced support for the Transformers v5.0 release candidates, but this release is adding support for the full release. The intention is to maintain backward compatibility with v4.x. The library includes dual CI testing for both version for now, allowing users to upgrade to the newest Transformers features when ready. In future versions, Sentence Transformers may start requiring Transformers v5.0 or higher.

All Changes

• Introduce compatibility with transformers 5.0.0rc01 by @​tomaarsen (huggingface/sentence-transformers#3597)
• Specify numpy manually in dependencies, as it's directly used/imported by @​tomaarsen (huggingface/sentence-transformers#3608)
• Expand test suite to full transformers v5 by @​tomaarsen (huggingface/sentence-transformers#3615)
