Pythonic mix-ins for ROOT classes.
This package is typically used as a dependency for uproot 3.x, to define methods on the classes that are automatically generated from ROOT files. This includes histograms (TH*) and physics objects like TLorentzVectors. The reason it's a separate library is so that we can add physics-specific functionality on a shorter timescale than we can update Uproot 3 itself, which is purely an I/O package.
Occasionally, this library is used without Uproot 3, as a way to make arrays of TLorentzVectors.
Note: this package is incompatible with awkward>=1.0 and uproot>=4.0! For Lorentz vectors, use vector. Since the versions of Awkward Array and Uproot that this is compatible with are deprecated, this library is deprecated as well.
Install uproot3-methods like any other Python package:
pip install uproot3-methods # maybe with sudo or --user, or in virtualenv- numpy (1.13.1+)
- Awkward Array 0.x
TBD.
