Number multiplication

To illustrate the basic working of the required by UbiOps we have created a sample deployment that multiplies a given number by 2. You can download the deployment package as a zip (ready to be used) here.

We have put the here as well for your reference:

class Deployment:

    def __init__(self, base_directory, context):

        print("Initialising deployment")

    def request(self, data):

        print("Processing request")
        # Retrieve the user input from the data dictionary
        user_input = data['number']

        # Process the input
        number_multiplied = user_input * 2

        # Return the output
        return {'number_multiplied': number_multiplied}

In the __init__ method a deployment is initialized. It can for example be used for loading modules that have to be kept in memory or setting up connections. In this example we do not need that. In the request method we process the given input. We first retrieve the user_input from the data dictionary and then multiply it by 2. The result of that multiplication is then returned as output number_multiplied.

Importing Python modules

Please note that this example does not require any Python modules and therefore has no import statements. If you need to import external modules then the import statements should precede Class Deployment. Be sure to also add the dependencies to the requirements.txt as well.

Running the example in UbiOps

To deploy this example model to your own UbiOps environment you can log in to the WebApp and create a new deployment in the deployment tab. You will be prompted to fill in certain parameters, you can use the following:

Deployment configuration
Name multiply
Description Multiplies input by 2
Input fields: name = number, datatype = integer
Output fields: name = number_multiplied, datatype = integer
Version name v1
Description leave blank
Language python 3.7
Upload code deployment zip do not unzip!

The advanced parameters and labels can be left as they are. They are optional.

After uploading the code and with that creating the deployment version UbiOps will start deploying. Once you're deployment version is available you can make requests to it. You can use any integer as input.
