import pandas as pd
import pickle as cpick

input = '/home/classic/data'
with open("".join([input, 'mappingFile.pkl']), mode='rb') as fp:
    mappingFile_pd = cpick.load(fp)

When I am trying to read a pkl file, I get this error “ImportError: No module named 'pandas.core.indexes”. What does this mean?
