DeprecationWarning: numpy.core.umath_tests
Alright so this is a deprecation warning on Python 3.x. 
Since, this is warning your code will run fine. It is not an error (When the code stops running by graceful degradation). 
The solution to remove this error is as follow:

As I can see you have Scikit-Learn version 0.19.2 installed you need to get the latest version. To do so enter the following command  pip3 install --force-reinstall scikit-learn==0.20rc1  This will install the latest versions of scikit-learn, scipy and numpy. Your deprecation warnings will now not exist. 
Although you'll next get a new warning. This time regarding the file in the scikit-learn library called cloudpickle \sklearn\externals\joblib\externals\cloudpickle\cloudpickle.py.  To overcome this warning you got to edit the code which python shows us.  Just do a sudo idle3 onto the file and edit the lines which says :  import imp  from imp import find_module to import importlib  Next go to the funtion find_module and change the line  file, path, description = find_module(path) to file, path, description = importlib.utils.find_spec(path).

This must solve the deprecation warnings in the scikit-learn libraries.
I'm trying to run this python script below:
import pandas as pd
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score
from sklearn.metrics import confusion_matrix 
It gives me the error below.

Warning (from warnings module):   File
  "C:\Users\Dipali\AppData\Local\Programs\Python\Python37-32\lib\site-packages\sklearn\ensemble\weight_boosting.py",
  line 29     from numpy.core.umath_tests import inner1d
  DeprecationWarning: numpy.core.umath_tests is an internal NumPy module
  and should not be imported. It will be removed in a future NumPy
  release.

What I need to do?
