Code Review

This pull request adds a new tutorial for running InternVL series models on a single NPU. The tutorial is well-structured and provides clear instructions for both offline inference and online serving. However, there is a significant issue with the model path used in the examples, which points to a non-public model. This will prevent users from following the tutorial. My review includes a comment to address this.

Please add an accuracy test with same parameter with doc before merge.
