Launch a Session

Sessions allow you to perform actions such as run R or Python code. They also provide access to an interactive command prompt and terminal. This topic demonstrates how to launch a new session.

  1. Navigate to your project's Overview page.
  2. Click New Session.
  3. Check the settings for your session:
    You see the following settings:
    Editor
    Selects the Editor; currently only Workbench is supported and therefore the selector is static.
    Kernel
    Selects the Kernel. Initially only Python Runtimes are supported.
    Engine Image
    Displays the Advanced tab in Project Settings and allows you to set environment variables and the shared memory limit.
  4. You can modify the engine image used by this session:
    1. By Engine Image, click Configure.
      Cloudera AI displays the Project Settings page.
    2. Select the Runtime/Engine tab.
    3. Next to Default Engine, select ML Runtime or Legacy Engine.
    4. Click Save Engine.
  5. Specify your Resource Profile.
    This attribute will define how many vCPUs and how much memory will be reserved to run the workload (for example, session including the runtime itself). The minimum configuration is 1vCPU and 2 GB memory.
  6. Click Start Session.
    The command prompt at the bottom right of your browser window will turn green when the engine is ready. Sessions typically take between 10 and 20 seconds to start.
