All actions for files and folders can be found in the SDK references:

​
Create New Folder

The following script creates a new folder in the root directory of Files. Ensure that you:

  • Replace <private_key_path> with the path to your private key.
  • Replace <folder_name> with the name you want to give your folder. We recommend using unique folder names.
  • Replace A folder to store my files with a meaningful description for your folder.
  • Replace my: folder_metadata with any metadata you want to add to the folder. Remove the line if you do not want to add any metadata to the folder.
from encord import EncordUserClient

# Instantiate Encord client by substituting the path to your private key
user_client = EncordUserClient.create_with_ssh_private_key(
                ssh_private_key_path="<private_key_path>"
            )



# Create a storage folder
folder_name = "<folder_name>"
folder_description = "A folder to store my files"
folder_metadata = {"my": "folder_metadata"}
storage_folder = user_client.create_storage_folder(folder_name, folder_description,client_metadata=folder_metadata)

​
Register Cloud Data

The following scripts initiate uploads from your cloud storage to a specified folder in Encord using a properly formatted JSON upload file. It works for all file types.

If Upload is still in progress, try again later! is returned, use the script to check the upload status to see whether the upload has finished.

Ensure that you:

  • Replace <private_key_path> with the path to your private key.
  • Replace <integration_title> with the title of the integration you want to use.
  • Replace <folder_name> with the folder name. The scripts assume that the specified folder name is unique.
  • Replace path/to/json/file.json with the path to a JSON file specifying which cloud storage files should be uploaded.
  • If creating a new folder, replace A folder to store my files with a meaningful description for your folder.
  • If creating a new folder, replace "my": "folder_metadata" with any metadata you want to add to the folder.

else:

To update client metadata, include the "upsert_metadata": true flag in the upload JSON file. It can only be used in conjunction with "skip_duplicate_urls": true.

Use the following script to check the status of your private cloud registration.

If Upload is still in progress, try again later! is returned, run the script again to check the status at a later time.

Ensure that you:

  • Replace <upload_job_id> with the upload_job_id shown in the output of the script used to start the upload. In the example output of the script provided, the upload_job_id = c4026edb-4fw2-40a0-8f05-a1af7f465727.
  • Replace <private_key_path> with the path to your private key.
  • Replace <folder_name> with the folder name. The scripts assume that the specified folder name is unique.
# Import dependencies
from encord import EncordUserClient
from encord.orm.dataset import LongPollingStatus

upload_job_id = <upload_job_id>

# Authenticate with Encord using the path to your private key.

    print(f"No folder found with name {folder_name_to_find}")

# Check upload status
res = storage_folder.add_private_data_to_dataset_get_result(upload_job_id, timeout_seconds=5)
print(f"Execution result: {res}")

​
Register Cloud Data Without a JSON File

Instead of using a JSON file to specify cloud files and URLs, you can use DataUploadItems. This method is recommended for cloud data registrations in the specific use cases listed below.

​
Increased Image Group File Registration

You can increase the speed at which Image Groups are registered to Encord by including imageMetadata for each image belonging to the image group. For this you must use the following method of importing images and creating Image Groups.

When the audioMetadata, imageMetadata, or videoMetadata flags are present in the JSON file, we directly use the supplied metadata without performing any additional validation, and do not store the file on our servers. It is crucial that the metadata you provide is accurate.

Ensure that you:

  • Replace <path_to_private_key> with your private key path
  • Enter the URLs of images you want to import and batch as an image group.
  • Provide the imageMetadata for your files by replacing the example values.
  • Enter a title and an optional description for your image group.
  • Specify the name of the target folder to store the image group.
  • Replace <integration_id> with the id of the integration you want to use for the data registration.
from encord.orm.storage import DataUploadImageGroup, DataUploadImageGroupImage

# Enter the URLs of images you want to add to the Image Group
private_cloud_urls = [
    "cloud/path/image1.jpg",
    "cloud/path/image2.jpg",
    "cloud/path/image3.jpg",
]

# Define the new image group using DataUploadImageGroup and DataUploadImageGroupImage

            ),
        )
        for private_cloud_url in private_cloud_urls
    ],

        image_groups=[image_group]  # Add the new image group
    ),
    ignore_errors=True
)

# Monitor the upload status

else:
    print("Error registering image group.")

​
Create an Image Group from Existing Images

You can create Image Groups from individual images previously added to Encord. If the individual images include clientMetadata and are then grouped into an Image Group, this metadata is retained at the frame level within the Image Group.

The following script combines three previously uploaded images in Encord into a single Image Group.

In the following script:

  • Replace <private_key_path> with your private key path.
  • Replace the titles in the file_names list with the names of images to be grouped.
  • Replace <folder_name> with the title for the folder containing the files.
  • Provide a title for the image group.
  • Replace <integration_id> with the ID of the integration being used.
  • Add optional clientMetadata for the image group.

Local Data

​
Upload Local Data to an Existing Folder

The following scripts add data to a folder that already exists in Files.

  • Replace <folder_name> with the name of the folder you want to add data to.
  • For images and videos replace User/path/to/my/file with the path to your image or video file.
  • For DICOM series replace User/path/to/dicom/file1 and User/path/to/dicom/file2 with the paths to the DICOM files you want to create a series from. Add as many file paths as necessary.
  • For image groups and image sequences, replace User/path/to/image/file1 and User/path/to/image/file2 with the paths to the image files you want to create an image group or image sequence from. Add as many file paths as necessary.
from encord import EncordUserClient
from encord.storage import FoldersSortBy

# Instantiate Encord client by substituting the path to your private key
user_client = EncordUserClient.create_with_ssh_private_key(

​
Upload Local Data to a New Folder

The following script creates a new folder in Files and uploads image, video, DICOM, image group, or image sequence files to the newly created folder. A new folder is created each time the script is run.

In the following scripts, ensure that you:

  • Replace <private_key_path> with the path to your private key.
  • Replace <folder_name> with the name you want to give your folder. The scripts assume that the specified folder name is unique.
  • Replace A folder to store my files with a meaningful description for your folder.
  • Replace my: folder_metadata with any metadata you want to add to the folder. Remove the line if you do not want to add any metadata to the folder.
  • For images and videos replace User/path/to/my/file with the path to your image or video file.
  • For DICOM series replace User/path/to/dicom/file1 and User/path/to/dicom/file2 with the paths to the DICOM files you want to create a series from. Add as many file paths as necessary.
  • For image groups and image sequences, replace User/path/to/image/file1 and User/path/to/image/file2 with the paths to the image files you want to create an image group or image sequence from. Add as many file paths as necessary.

​
List Data Units in a Folder

Listing the files in a folder can be used to verify that all data unit were successfully uploaded.

  • Replace <private_key_path> with the path to your private key.
  • Replace <folder_name> with the name you want to give your folder. The scripts assume that the specified folder name is unique.
