# Selecting computing resources

When you run your first computations, you can select a [configuration](../../concepts/configurations.md) for your notebook from the list of configurations available in the project. You will see utilization rates for each type of VM configurations. VMs marked in green are ready to start as soon as you select them. Those marked in yellow require further setup. The start time of such VMs will be longer. The configurations marked in red are currently in use and may take indefinite time to become available, as another user must release them first.

Open the DataSphere project:

1. Select the project in your community or on the DataSphere [home page](https://datasphere.yandex.cloud) in the **Recent projects** tab.
1. Click **Open project in JupyterLab** and wait for the loading to complete.
1. Open the notebook tab.

## Changing the configuration {#config}

You cannot change the configuration of computing resources while preserving the interpreter state. However, you can add another configuration to your project and rerun the computations.
