This function declares Python requirements through \'reticulate\' using \'py_require()\' (uv-backed in reticulate >= 1.41), then validates imports for all required modules (numpy, scikit-learn, joblib, PyTorch). Run this once after installing the package. This is kept separate from model functions so that package installation never happens automatically during normal use.
Details
The function performs the following steps:
Declares requirements with
reticulate::py_require().Initializes Python through reticulate's managed environment.
Verifies all packages can be imported.
