browser_chat Error: [Errno 99] Cannot assign requested address

Bug description Followed the setup instructions here https://github.com/facebookresearch/ParlAI/tree/master/parlai/chat_service/services/browser_chat, but when I run the client script I get this error:

Connecting to port:  10001
[Errno 99] Cannot assign requested address
Connection closed

Reproduction steps python3 parlai/chat_service/services/browser_chat/client.py --port 10001

Expected behavior Be able to chat with the model on a browser page.

Additional context I tried to run the client.py inside a docker image which published and exposed ports 8080, 80 and 10001 while the run.py was running in a docker image which exposed port 10001.

LITTLE BUG First time I run it, I got ModuleNotFoundError: No module named 'tornado’. Solved it installing tornado with python3 -m pip install tornado.

Sure, these are the things I remember I had some trouble with, but I’m new also to docker so they may be trivial:

• Trying to train the model during building: this can’t be done because it is not possible to use the GPUs, that can be used just at run time. Also, the availability of the GPUs must be checked at run-time.
• Missing wget and tornado as I mentioned in other issues (my start image was 10.0-cudnn7-devel-ubuntu18.04), that were not installed during setup
• To use chat_browser, --network==host must be specified as an arg of the run command in both the server and client container

If anything else comes to my mind I will edit this post.

I’m sorry, this was really an issue regarding Docker. I had to use --network==host to expose my ports. I’m closing this issue.
