"""
|

|
|
This file test accuracy of the vLLM server via LMEval.
|
||
|
|
It uses local-completions, which interacts with vLLM
|
||
|
|
through the OAI API with N concurrent connections.
|
||
|
|
This simulates real work usage of the API and makes
|
||
|
|
sure that the zmq frontend mp RPC message passing and
|
||
|
|
AsyncLLMEngine are working correctly.
