It seems like only stderr is logged in my space – I’m using gradio running in a Docker container. Is this expected? I can’t find it documented anywhere.

I think stdout is also output to the log in the Gradio space. (It will be displayed if you print it.)  
I wonder if this is a specification for the Docker space only, or if it depends on the Gradio startup options…  
I’ve never heard of any documentation on this.

You might want to try adding `ENV PYTHONUNBUFFERED=1` to your Dockerfile.

That’s a great idea. I wondered if it is related to buffering. I’ll try this out later today.

It worked! I also made a PR with this change to [sayakpaul/demo-docker-gradio · Disable python buffering](https://huggingface.co/spaces/sayakpaul/demo-docker-gradio/discussions/3)
