retriever-redis image can NOT be launched

[lianhao]

Building the latest (commt id de27e6b) retriever-redis image following the README, then launch with it with docker, will find that image can not be launched at all. The container logs shows the following error:

$ sudo docker logs retriever-redis-server

You may be able to resolve this warning by setting `model_config['protected_namespaces'] = ()`.

Which one did you use to build your image?

Most likely duplicate of #395?

Seems right, looks like module 'uvicorn' is not installed during docker image build time. I guess this will affect all uservices using mega core

Looks like PR #404 has fixed this issue. Close it now.
