Pharmpy is a library and toolkit for pharmacometrics. It can be used as a regular Python package, in R via the pharmr package or via its built in command line interface.
Current features:
- A model abstraction as a foundation for higher level operations on models
- Functions for manipulation of models, e.g. changing model components like elimination or absorption
- Reading NONMEM models and results
- Running models and complex workflows (with NONMEM or to some extent nlmixr)
For installation in R see pharmr.
Install the latest stable version from PyPI:
pip install pharmpy-core # or 'pip3 install' if that is your default python3 pipTo be able to use components using machine learning the tflite package is needed. It can be installed using:
pip install --index-url https://google-coral.github.io/py-repo/ tflite_runtime>>> from pharmpy.modeling import read_model, read_modelfit_results
>>> model = read_model("run1.mod")
>>> res = read_modelfit_results("run1.mod")
