Importing images from an Amazon S3 bucket
The images are imported from an Amazon S3 bucket. You can use the console bucket, or another Amazon S3 bucket in your AWS account. If you are using the console bucket, the required permissions are already set up. If you are not using the console bucket, see Accessing external Amazon S3 Buckets.
Note
You can't use the AWS SDK to create a dataset directly from images in an Amazon S3 bucket. Instead, create a manifest file that references the source locations of the images. For more information, see Using a manifest file to import images
During dataset creation, you can choose to assign label names to images based on the name of the folder that contains the images. The folder(s) must be a child of the Amazon S3 folder path that you specify in S3 folder location during dataset creation. To create a dataset, see Creating a dataset by importing images from an S3 bucket.
For example, assume the following folder structure in an Amazon S3 bucket. If you specify the Amazon S3 folder location as S3-bucket/alexa-devices, the images in the folder echo are assigned the label echo. Similarly, images in the folder echo-dot are assigned the label echo-dot. The names of deeper child folders aren't used to label images. Instead, the appropriate child folder of the Amazon S3 folder location is used. For example, images in the folder white-echo-dots are assigned the label echo-dot. Images at the level of the S3 folder location (alexa-devices) don't have labels assigned to them.
Folders deeper in the folder structure can be used to label images by specifying a deeper S3 folder location. For example, If you specify S3-bucket/alexa-devices/echo-dot, Images in the folder white-echo-dot are labeled white-echo-dot. Images outside the specified s3 folder location, such as echo, aren't imported.
S3-bucket └── alexa-devices ├── echo │ ├── echo-image-1.png │ └── echo-image-2.png │ ├── . │ └── . └── echo-dot ├── white-echo-dot │ ├── white-echo-dot-image-1.png │ ├── white-echo-dot-image-2.png │ ├── echo-dot-image-1.png ├── echo-dot-image-2.png ├── . └── .
We recommend that you use the Amazon S3 bucket (console bucket) created for you by Amazon Rekognition when you first opened the console in the current AWS region. If the Amazon S3 bucket that you are using is different (external) to the console bucket, the console prompts you to set up appropriate permissions during dataset creation. For more information, see Step 2: Set up Amazon Rekognition Custom Labels console permissions.
Creating a dataset by importing images from an S3 bucket
The following procedure shows you how to create a dataset using images stored in the Console S3 bucket. The images are automatically labeled with the name of the folder in which they are stored.
After you have imported your images, you can add more images, assign labels, and add bounding boxes from a dataset's gallery page. For more information, see Labeling images.
Upload your images to an Amazon Simple Storage Service bucket
Create a folder on your local file system. Use a folder name such as alexa-devices.
Within the folder you just created, create folders named after each label that you want to use. For example, echo and echo-dot. The folder structure should be similar to the following.
alexa-devices ├── echo │ ├── echo-image-1.png │ ├── echo-image-2.png │ ├── . │ └── . └── echo-dot ├── echo-dot-image-1.png ├── echo-dot-image-2.png ├── . └── .Place the images that correspond to a label into the folder with the same label name.
Sign in to the AWS Management Console and open the Amazon S3 console at https://console.aws.amazon.com/s3/
. Add the folder you created in step 1 to the Amazon S3 bucket (console bucket) created for you by Amazon Rekognition Custom Labels during First Time Set Up. For more information, see Managing an Amazon Rekognition Custom Labels project.
Open the Amazon Rekognition console at https://console.aws.amazon.com/rekognition/
. Choose Use Custom Labels.
Choose Get started.
In the left navigation pane, choose Projects.
In the Projects page, choose the project to which you want to add a dataset. The details page for your project is displayed.
Choose Create dataset. The Create dataset page is shown.
In Starting configuration, choose either Start with a single dataset or Start with a training dataset. To create a higher quality model, we recommend starting with separate training and test datasets.
Choose Import images from Amazon S3 bucket.
In S3 URI, enter the Amazon S3 bucket location and folder path.
Choose Automatically attach labels to images based on the folder.
Choose Create Datasets. The datasets page for your project opens.

If you need to add or change labels, do Labeling images.
Follow the steps in Training a model (Console) to train your model.
