QUESTION
I am trying to load a Higgs Boson dataset from uproot. I am not comfortable with the use of uproot and the .root data type. I am using the following code which is a sort of official instructions to load the library. I have made a virtual environment and installed the necessary libraries
...ANSWER
Answered 2018-Mar-08 at 06:33Python 2 and 3 differ in their treatment of byte strings versus unicode strings: Python 2 implicitly converts (weakly, dynamically typed), but Python 3 complains (strongly, dynamically typed).
Names that come from ROOT files are byte strings because ROOT provides no encodings. They're all just "char *". The appropriate Python type is byte string.
OAMap just doesn't want to deal with this— array names are strings, meaning anything in unicode. In Python 2, an encoding is implicitly assigned to make this true; Python 3 is stricter about how the encoding is assigned. Its connector to ROOT might be missing cases to handle unencoded byte strings.
Switch to Python 2 for an easy fix.

Install oamap
You can use oamap like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
