Problem installing root_numpy

ROOT
1

Hi guys,

I have trouble installing root_numpy and root_pandas, I want to use an analysis about LHCb open data and I need this two packages to work with it.

the error message when I run the command pip install --user root_numpy is

Hi @Adrianodelvincio!

Sorry, we can’t help here. The root_numpy and root_pandas packages are not part of ROOT, and they are both deprecated and unmaintained:

Please don’t use them, it’s probably very difficult to get them to compile now.

If you want to get NumPy arrays out of ROOT files, you should better use directly. You can open the files with RDataFrame and then use AsNumpy() to get your arrays. Alternatively, you can also do your analysis completely in RDataFrame to begin with, or if you don’t want to use ROOT you can install the uproot python package that succeeded root_numpy.

Thank you for your answer.

Yeah, I know I can use different solution with root dataframe, the problem is that this analysis is 7 years old, so I need to write in a different way the code they used. The code is not updated, so there is no solution at this point.
