Check your pandas version.

df.set_value() is deprecated since pandas version 0.21.0

Instead use df.at

import pandas as pd

df = pd.DataFrame({"A":[1, 5, 3, 4, 2], 
                   "B":[3, 2, 4, 3, 4],  
                   "C":[2, 2, 7, 3, 4], 
                   "D":[4, 3, 6, 12, 7]}) 

df.at[2,'B']=100

   A    B  C   D
0  1    3  2   4
1  5    2  2   3
2  3  100  7   6
3  4    3  3  12
4  2    4  4   7
