Alright I found the issue, totally understandable you did not get it to work 😬 Give me a few minutes to write up the solution for you.

First, it could be that an outdated

protobuf

version is installed in the environment, thereby breaking

streamlit

. To fix this you can add

pip install --upgrade protobuf

to the environment (the one in which you installed

streamlit

and

plotly

). Second, because you are not using the template streamlit service that we offer, there are a few changes you need to make to its configuration. 1. Again go to Services > Edit Services > Streamlit 2. Replace the image by your custom environment (you did this correct!) 3. Change the "Command (optional)" to:

-c 'umask 002 && streamlit run /project-dir/streamlit.py'

4. Add a file called

streamlit.py

in your project directory. You can do this through the JupyterLab UI. 5. Restart the session for the changes to take effect. 6. You should now be able to visit your streamlit dashboard. Example `streamlit.py`:

import streamlit as st

st.title("Hello Streamlit")

Let me know whether that does the trick. 😄
