Hosting the custom authentication validation model

Let's now create the API that will accept the login attempt from the user and return its confidence in the validity of the login:

1. We begin by importing the required modules for creating a Flask server, as shown:

from sklearn.externals import joblibfrom flask import Flask, request, jsonifyfrom string import digitsimport sysimport osimport jsonimport pandasimport numpyimport optparsefrom keras.models import Sequential, load_modelfrom keras.preprocessing import sequencefrom keras.preprocessing.text import Tokenizerfrom collections import OrderedDict

2. We now need to import the saved model and weights from the model training step. Once we do so, we need to recompile the model and make its
