### Reproduction

1. Go to In https://huggingface.co/docs/transformers/performance
2. Click link with "DeepSpeed-Infinity" text
3. Get site that says "The documentation page DEEPSPEED doesn’t exist in v4.18.0, but exists on the main version. Click here to redirect to the main version of the documentation."
