 An alternative to launching the evaluation locally is to serve the model on a TGI-compatible server/container and then run the evaluation by sending requests to the server. The command is the same as before, except you specify a path to a yaml config file (detailed below):

 ### Using the dummy model
 To debug or obtain random baseline scores for a given set of tasks, you can use the `dummy` model:

 ## How to navigate this project
 `lighteval` is supposed to be used as a standalone evaluation library.
-- To run the evaluations, you can use `run_evals_accelerate.py` or `run_evals_nanotron.py`.
+- To run the evaluations, you can use `lighteval accelerate` or `lighteval nanotron`.
