Hi,

maybe try instead

pip3 install root_pandas --user

It works for me.

Thank you so much for your reply. It has been installed, but I do not understand why am I getting the error again,
3 import numpy as np
4 import pandas as pd
----> 5 import root_pandas as rpd
6 from ROOT import TFile, TH1F
7 import copy

ImportError: No module named root_pandas

I bet this happened because you confused python2 with python3. Which executable you ran for your test above, python or python2 or python3?

python3, I got this,
[sraj@lxplus7101 ~]$ python3
