The Problem 🔗
When using PyCall.jl with Python executables and packages managed by uv, PyCall can find the Python executable in the virtual environment but doesn’t recognize packages installed via uv add.
The Solution 🔗
Add the uv virtual environment’s site-packages to Python’s path before importing packages:
pushfirst!(pyimport("sys")."path", realpath(".venv/lib/python3.11/site-packages/"))
This prepends the uv virtual environment’s package directory to Python’s module search path, allowing PyCall to find all packages installed via uv.
Note: Adjust the Python version in the path (python3.11) to match your virtual environment’s Python version.
