Use Keras to recognize hand-written digits with Watson Machine Learning REST API

This notebook contains steps and code to demonstrate support of Keras Deep Learning experiments in Watson Machine Learning Service. It introduces commands for getting data, training experiments, persisting pipelines, publishing models, deploying models and scoring.

Some familiarity with cURL is helpful. This notebook uses cURL examples.

Learning goals

The learning goals of this notebook are:

Working with Watson Machine Learning experiments to train Deep Learning models.
Downloading computed models to local storage.
Online deployment and scoring of trained model.

This notebook contains the following parts:

1. Set up the environment

Before you use the sample code in this notebook, you must perform the following setup tasks:

Contact with your Cloud Pack for Data administrator and ask him for your account credentials

Connection to WML

Authenticate the Watson Machine Learning service on IBM Cloud Pack for Data. You need to provide platform url, your username and password.

In [ ]:

%env USERNAME=
%env PASSWORD=
%env DATAPLATFORM_URL=

%env SPACE_ID=

Getting WML authorization token for further cURL calls

Example of cURL call to get WML token

In [2]:

%%bash --out token

token=$(curl -sk -X GET \
    --user $USERNAME:$PASSWORD \
    --header "Accept: application/json" \
    "$DATAPLATFORM_URL/v1/preauth/validateAuth")

token=${token#*accessToken\":\"}
token=${token%%\"*}
echo $token

In [3]:

%env TOKEN=$token

Out[3]:

Space creation

Tip: If you do not have space already created, please convert below three cells to code and run them.

First of all, you need to create a space that will be used in all of your further cURL calls. If you do not have space already created, below is the cURL call to create one.

<a href="https://cpd-spaces-api.eu-gb.cf.appdomain.cloud/#/Spaces/spaces_create" target="_blank" rel="noopener no referrer">Space creation

%%bash --out space_id

curl -sk -X POST \
    --header "Authorization: Bearer $TOKEN" \
    --header "Content-Type: application/json" \
    --header "Accept: application/json" \
    --data '{"name": "curl_DL"}' \
    "$DATAPLATFORM_URL/v2/spaces" \
     | grep '"id": ' | awk -F '"' '{ print $4 }'

space_id = space_id.split('\n')[1]
%env SPACE_ID=$space_id

Space creation is asynchronous. This means that you need to check space creation status after creation call. Make sure that your newly created space is active.

Get training details

Treining is an asynchronous endpoint. In case you want to monitor training status and details, you need to use a GET method and specify which training you want to monitor by usage of training ID.

Please make sure that training is completed before you go to the next sections. Monitor state of your training by running above cell couple of times.

4. Historical runs

In this section you will see cURL examples describing how to get historical training runs information.

Output should be similar to the output from training creation but you should see more trainings entries. Listing trainings:

5. Deploy and Score

In this section you will learn how to deploy and score pipeline model as webservice using WML instance.

Before deployment creation, you need store your model in WML repository. Please see below cURL call example how to do it.

Download request.json with repository request json for model storing.

In [20]:

%%bash --out request_json

curl -sk -X GET \
    --header "Authorization: Bearer $TOKEN" \

    | python -m json.tool

You can specify user_defined_objects if keras model used any

In [21]:

Prepare scoring input data

Hint: You may need to install numpy using following command !pip install numpy

In [36]:

import numpy as np

mnist_dataset = np.load('mnist.npz')
test_mnist = mnist_dataset['x_test']

In [37]:

image_1 = (test_mnist[0].ravel() / 255).tolist()
image_2 = (test_mnist[1].ravel() / 255).tolist()

In [42]:

%matplotlib inline
import matplotlib.pyplot as plt

In [43]:

for i, image in enumerate([test_mnist[0], test_mnist[1]]):
    plt.subplot(2, 2, i + 1)
    plt.axis('off')
    plt.imshow(image, cmap=plt.cm.gray_r, interpolation='nearest')
