Cloud streamlit will not load plotly_express

[WorthingtonR]

My app works locally. Installation error:

Collecting plotly_express
Downloading plotly_express-0.4.1-py2.py3-none-any.whl (2.9 kB)
Collecting streamlit`
Downloading streamlit-1.27.2-py2.py3-none-any.whl (7.6 MB)
ERROR: Could not find a version that satisfies the requirement collections (from versions: none)

You should consider upgrading via the '/home/appuser/venv/bin/python -m pip install --upgrade pip' command.

I don't know what this means. I built the app using the latest version of pip.

Hi @WorthingtonR!

Plotly Express should work seamlessly with Streamlit.

I noticed streamlit-1.27.2-py2.py3-none-any.whl in the error log trace. Could you please share your requirements.txt file?

Thank you,
Charly

The streamlit cloud works differently than local.host. No problem with the requirements.txt file. I modified the file to include only these files and it worked:

numpy

pandas

plotly.express

streamlit

Was able to access my script easily after that.

Thanks for the quick response.
