hi! Trying to run streamlit apps in pants. How can I do it once it can only run through its CLI?

Hi @breezy-apple-27122 ๐Ÿ‘‹ I have no idea what you just asked ๐Ÿ˜‰ --so more context needed or hope others know streamlit to fill you in

So you add the commands in a python script and then use the cli to run it

Thanks a lot!

youโ€™re welcome. and feel free to keep asking questions. ๐Ÿ‘
in pants 2.16 it will be possible to streamline this even more with providing the
run streamline/demo.py
directly in the BUILD file..

I'm still getting issues on running. Don't know why actually
Copy code
rhuan@Rhuans-Laptop python % ./pants run src/streamlit/template:bin -- run streamlit/main.py
pyenv: python3.11: command not found

The `python3.11' command exists in these Python versions:
  3.11.1

Note: See 'pyenv help global' for tips on allowing both
      python2 and python3 to be found.
The issue is that pants can only run on python 3.9 and I want to run streamlit in python 3.11
is v2.15 compatible with python 3.11?
I solved the issue by installing pants through homebrew
but as you said it's not working properly

We are on pants 2.15, and this is working using pants cli. Question is, how to run the packaged pex_binary? Seems like it is not possible to point streamlit to the script file within the pex?

FWIW, I got my streamlit app working with this config:
Copy code
pex_binary(
    name="dashboard",
    execution_mode="venv",
    script="streamlit",
    args=["run", "ux/dashboard.py"],
    dependencies=["//ux/dashboard.py", "//:root#streamlit"],    
)
And then I can run
./dist/ux/dashboard.pex
