Issue Running Python Application with Bazel - ImportError with NumPy C-Extensions

[ModiCodeCraftsman]

🐞 bug report

Affected Rule

The issue is caused by the rule: py_binary

Is this a regression?

No

Description

When running a py_binary target with dependencies that include NumPy and other libraries requiring C-extensions, the runtime fails to locate the required C-extension libraries. This results in an ImportError for NumPy's C-extensions, even though the same environment works correctly when run outside of Bazel in a local virtual environment.
