Streamlit using system packages despite running out of venv

Using Streamlit
1

streamlit version: 1.41.1
OS: archlinux
(running on local machine)

Summary:
Streamlit uses my archlinux python-numpy-2.2.1-2 despite running out a venv with numpy 1.23.1 version installed.

More details:
Due to some dependency issues between numpy, bokeh and the python version itself, I need to run

python 3.10.16
bokeh 2.4.3
numpy 1.23.1

I tried setting this up using pyenv and pipenv and alternatively uv , to the same result.

If I activate the venv and run streamlit, it uses the python 3.10.16 version BUT still uses my system’s numpy 2.2.1 , which is not compatible with the rest of the setup.

I would appriciate any tips on howto resolve this issue.

Your system’s numpy is built and installed for python 3.13, there is no chance that your python 3.10 is using it.

Hi,

this is also irritating me, but here is a log (I redacted some user paths):


  You can now view your Streamlit app in your browser.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.10 from "<redacted>/.venv/bin/python3"
  * The NumPy version is: "2.2.1"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: No module named 'numpy._core._multiarray_umath'


The above exception was the direct cause of the following exception:

That is weird and I cannot explain how it can happen. I am unable to reproduce something like that myself.

There might be a PATH misconfiguration or something that is prioritizing a global installation. Can you uninstall numpy from your global environment and then try again to create a clean environement and install numpy there?
