❓ General Questions

When I create two instance of MLCEngine, each of them always generate: Role "user" is not supported.

@wqwz111 would be great if you can send in a python snippet that reproduces the error, we would be happy to look into it. Although in general we recommend running a single MLCEngine, if there is a need to support multiple models, likely extending the engine to do so would be more efficient

Thanks! I will try extending the engine to solve my problem.
