Import Error

Seeking Help Research numpy/pandas

I got the following error for trying import a valid pandas library.

InputRejected: Importing scatter_matrix from pandas.plotting raised an
ImportError. No modules or attributes with a similar name were found.
Our security system is concerned. If you continue to have import
errors, your account will be suspended until a human can talk to you.

Here is my code:

#map correlations  
from pandas.plotting import scatter_matrix

attributes = ['p_ON', 'i_1', 'i_4', 'i_8', 'i_27']  
scatter_matrix(housing[attributes], figsize = (12, 8))

Does anyone know why this is happening? Is quantopian using an outdated version of pandas?

Quantopian currently uses pandas version 0.18.1 which has the modules referenced differently. So, use the following instead

from pandas.tools.plotting import scatter_matrix

Then something like below will work. Check the pandas 0.18 docs (https://pandas.pydata.org/pandas-docs/version/0.18.0/visualization.html#scatter-plot) to ensure the parameters haven't changed too.

import pandas as pd  
import numpy as np


from pandas.tools.plotting import scatter_matrix  
df = pd.DataFrame(np.random.randn(1000, 4), columns=['a', 'b', 'c', 'd'])  
scatter_matrix(df, alpha=0.2, figsize=(6, 6), diagonal='kde')

Good luck!
