        uproot (originally μproot, for "micro-Python ROOT") is a reader and a writer of the `ROOT file format <https://root.cern/>`__ using only Python and Numpy. Unlike the standard C++ ROOT implementation, uproot is only an I/O library, primarily intended to stream data into machine learning libraries in Python. Unlike PyROOT and root_numpy, uproot does not depend on C++ ROOT. Instead, it uses Numpy to cast blocks of data from the ROOT file as Numpy arrays.
        
        Python does not necessarily mean slow. As long as the data blocks ("baskets") are large, this "array at a time" approach can even be faster than "event at a time" C++. Below, the rate of reading data into arrays with uproot is shown to be faster than C++ ROOT (left) and root_numpy (right), as long as the baskets are tens of kilobytes or larger (for a variable number of muons per event in an ensemble of different physics samples; higher is better).

        uproot is not maintained by the ROOT project team, so post bug reports here as `GitHub issues <https://github.com/scikit-hep/uproot/issues>`__, not on a ROOT forum. Thanks!

        Installation
        ============
        
        Install uproot like any other Python package:
        
        .. code-block:: bash
        
            pip install uproot                       # maybe with sudo or --user, or in virtualenv
        
        or install with `conda <https://conda.io/en/latest/miniconda.html>`__:
        
        .. code-block:: bash
        
            conda config --add channels conda-forge  # if you haven't added conda-forge already
            conda install uproot
        
        The pip installer automatically installs strict dependencies; the conda installer also installs optional dependencies (except for Pandas).
        
        Strict dependencies:
        --------------------
        
        - `numpy <https://scipy.org/install.html>`__ (1.13.1+)
        - `awkward-array <https://github.com/scikit-hep/awkward-array>`__ (0.12.0+)
        - `uproot-methods <https://github.com/scikit-hep/uproot-methods>`__ (0.7.0+)
        - `cachetools <https://pypi.org/project/cachetools>`__
        
        Optional dependencies:
        ----------------------
        
        - `lz4 <https://pypi.org/project/lz4>`__ to read/write lz4-compressed ROOT files
        - `xxhash <https://pypi.org/project/xxhash/>`__ to read/write lz4-compressed ROOT files
        - `lzma <https://pypi.org/project/backports.lzma>`__ to read/write lzma-compressed ROOT files in Python 2
        - `xrootd <https://anaconda.org/conda-forge/xrootd>`__ to access remote files through XRootD
        - `requests <https://pypi.org/project/requests>`__ to access remote files through HTTP
        - `pandas <https://pandas.pydata.org>`__ to fill Pandas DataFrames instead of Numpy arrays
        
        **Reminder: you do not need C++ ROOT to run uproot.**
        
        Testing and development requirements
        ------------------------------------
        
        The packages need to run the test suite can be installed via ``pip install
        "uproot[testing]"``. Here is an example how to set up a development
        
        .. code-block:: bash
        
            git clone https://github.com/scikit-hep/uproot.git  # alternatively your own fork
            cd uproot
            python -m venv venv  # create a virtual environment in the folder venv
            . venv/bin/activate  # activate the Python environment
            pip install -e ".[testing]"   # installs uproot in editable mode with all packages required for testing
            pytest               # run the test suite
