Machine Learning with Clever Grid

Concepts in Clever Grid

Clever Grid is the machine learning oriented platform by Clever Cloud. It provides a unified GPU ecosystem to run your scripts.

Organization, Application, Add-on

In Clever Grid you create some applications under one organization. Organization is useful to manage roles and team collaboration.

An application is a stateless virtual machine which runs your code.

Additionally to an application, you can link one or more stateful virtual machine called add-on in Clever Grid. That lets you keep your data

Application as Runner, Application as Webapp

In some case, you may just need a one run of a script. To train a model or proceed a huge calculation for example. That the interest of Runner. A Runner runs a script and then go away.

A Webapp keeps the application up and serve via HTTP.

Create an application

1. Go to https://dashboard.clevergrid.io, create a “brand new application”.

   

2. Select the application type :
   • Docker (Runner | Webapp)

     

   • Python (Runner | Webapp)

     

   • Java (Runner | Webapp)

     

3. Select the size of your instance(s) and the number of nodes
4. (optional) You can choose a Template for your application

   Template will set up for you a compete ecosystem for a specific application. It provides add-ons and environment variables for you.

   • Jupyter Notebook
   • R Notebook
   • …

Create an add-on

1. Go to https://dashboard.clevergrid.io, Add a “a storage service”.

   

2. Select the storage plan you need
3. Link it to your applications
   Add-ons’s credentials will be automatically set up in your application. Yet it can be found on the “Add-on dashboard” tabs of your dashboard by the Clever Cloud console.

Set-up an application

You can pass some parameter to your application by environments variables.

• Go to dashboard.clevergrid.io and select your application
• Manage your environment variables by the tab “Environment variables”

  

Python applications

If there is a requirements.txt in the root folder of your application, dependencies will be installed during the deployment.

• Starting file
  • Clever Grid need to know which file runs to start your application. That can be a python file, declare in the CC_MLPYTHON_RUN_MAIN environment variable or custom bash script in CC_MLPYTHON_START_SCRIPT environment variable.
    It should contain the path of your main file. The path should be relative to the root of your repository.

For example, “pytorch.py” and “./pytorch.py are both valid. Bash scripts are expected to be executable (via chmod+x)

• Python version :
  • You can select the python version with the PYTHON_VERSION environment variable. Valid values are documented here: www.clever-cloud.com/doc/python/python_apps/#choose-python-version

Docker application

Refer to the Clever Cloud documentation : https://www.clever-cloud.com/doc/docker/

Java application

Refer to the Clever Cloud documentation : https://www.clever-cloud.com/doc/java/java-jar/

Hooking build steps

Between the build steps and before running the script, you can hook scripts. The hooks are documented here: https://www.clever-cloud.com/doc/clever-cloud-overview/hooks/ E.g. you can have a post build hook to initialize conda and stuff.

Send your code

Your Clever Grid application is now set up to receive your code.

• Go to your project and add the Clever Grid repository to your repository :

  git remote add clever-grid git+ssh://git@push-clevergrid-clevercloud-customers.services.clever-cloud.com/<APP_ID>
  

  You can find the repository address on the overview page of your application

  <figure class="cc-content-img"style="width:100%">
      <img src="/images/git-url.png" alt="git-url" class="img-fluid" data-action="zoom" />
      <figcaption>
          git-url
      </figcaption>
    </figure>

• Push your code

Command line management

In addition to the Clever Grid console, you can manage your add-ons and applications from the command line with Clever Tools.

see : https://www.clever-cloud.com/doc/clever-tools/getting_started/

Billing

Clever Grid application are reports on the Clever Cloud platform to billing purpose

• 1 GPU cost 10 euros by day. Charged per minute.
• Storage add-ons are based on the Clever Cloud billing : https://www.clever-cloud.com/en/pricing
