Using a prior dataset as a test dataset

Step 6: (Optional) Associate prior datasets with new projects

Amazon Rekognition Custom Labels now manages datasets with projects. Earlier (prior) datasets that you created are read-only and must be associated with a project before you can use them. When you open the details page for a project with the console, we automatically associate the datasets that trained the latest version of the project's model with the project. Automatic association of a dataset with a project doesn't happen if you are using the AWS SDK.

Unassociated prior datasets have never been used to train a model or, were used to train a previous version of a model. The Prior datasets page shows all of your associated and unassociated datasets.

To use an unassociated prior dataset, you create a new project on the Prior datasets page. The dataset becomes the training dataset for the new project. You can also create a project for an already associated dataset as prior datasets can have multiple associations.

To associate a prior dataset to a new project

  1. Open the Amazon Rekognition console at https://console.aws.amazon.com/rekognition/.

  2. In the left pane, choose Use Custom Labels. The Amazon Rekognition Custom Labels landing page is shown.

  3. In the left navigation pane, choose Prior datasets.

  4. In the datasets view, choose the prior dataset that you want to associate with a project.

  5. Choose Create project with dataset.

  6. On the Create project page, enter a name for your new project in Project name.

  7. Choose Create project to create the project. The project might take a while to create.

  8. Use the project. For more information, see Understanding Amazon Rekognition Custom Labels.

Using a prior dataset as a test dataset

You can use a prior dataset as the test dataset for an existing project by first associating the prior dataset with a new project. You then copy the training dataset of the new project to the test dataset of the existing project.

To use a prior dataset as a test dataset

  1. Follow the instructions at Step 6: (Optional) Associate prior datasets with new projects to associate the prior dataset with a new project.

  2. Create the test dataset in the existing project by using copying the training dataset from the new project. For more information, see Existing dataset.

  3. Follow the instructions at Deleting an Amazon Rekognition Custom Labels project (Console) to delete the new project.

Alternatively, you can create the test dataset by using the manifest file for prior dataset. For more information, see Creating a manifest file.
