   Replace `4.25.1` with the compatible version you found in step 1.
3. **Verify the downgrade**: Run `pip freeze` to check if the transformers version has been downgraded correctly.

#### Example Code

No code changes are required in this case. The fix involves downgrading a library, which can be done using pip.

#### Verification

To verify that the fix worked, try deploying your model with vllm==0.17.0 again. If the error is resolved, you should be able to deploy your model successfully.

#### Extra Tips

* Always check the documentation or source code of the library you're using to find the minimum required version.
* Be cautious when downgrading libraries, as it may break other dependencies or features in your project.
* Consider pinning your dependencies to specific versions in your `requirements.txt` file to avoid similar issues in the future.
