I was running rasa server(version:1.4.0a1) in enable-api mode.
I got an issue. After calling POST /model/train api, the server start to train model(by execute await train_async()). But while the model was training(precisely, train_async() was executing), the other call for other api(like GET /version, GET /, GET /webhooks/rest) was all pending until the model training finished.
Is there anything I can do to make it not pending while model is training?
Hey there @charlielin! I’m currently working on fixing this, there should be a fix soon
