Workflows and Stages

Workflow Basics

Encord SDK supports programmatic use of Workflows with the following: WorkflowStage, WorkflowAction, and Task. Typical use would be querying a WorkflowStage to get Tasks matching some criteria, and then executing a WorkflowAction against Tasks (for example: assigning, submitting annotation tasks, or accepting review tasks). The type of actions available depends on the stage queried. Here is a short description of major parts of the Workflows SDK:

WorkflowStage: Move your tasks through a Workflow Project using the WorkflowStage class. However, tasks CANNOT “teleport” through your Workflow. Tasks must move through the Workflow in logical order.
These are the stages currently supported:
- AnnotationStage
- ReviewStage
- ConsensusAnnotationStage
- ConsensusReviewStage
- FinalStage (Complete and Archive)
WorkflowAction: Applies an action to a task in a workflow stage The following actions are supported:
- assign: Assigns a user to one or more tasks.
- submit: Moves a task to the next stage.
- release: Releases a task from the current user.
- accept: Accepts a task.
- reject: Rejects a task.
Task: Exposes a simple version of the tasks available in a Project.
TaskStatus: The following statuses are available: The following statuses are available for ANNOTATE tasks:
- NEW: Tasks that are unassigned.
- ASSIGNED: Tasks that are assigned to a user.
- RELEASED: Tasks that were released from an assigned user.
- REOPENED: Tasks that were reopened.
- SKIPPED: Tasks that were skipped by annotators.
- COMPLETED: Tasks that are in the Complete stage. Used for Annotation sub-tasks in Consensus Annotation tasks.

Consensus Annotation tasks consist of 1 or more Annotation sub-tasks.

The following statuses are available for REVIEW and CONSENSUS REVIEW tasks:

NEW: Tasks that are unassigned.
ASSIGNED: Tasks that are assigned to a user.
RELEASED: Tasks that were released from an assigned user.
REOPENED: Tasks that were reopened.

In Consensus Projects, tasks in the COMPLETE and ARCHIVE blocks CANNOT be reopened.

View all stages in a Workflow

The following code provides you with the method to view all stages in a Workflow in a Project. The code is the same for Consensus and Non-Consensus Projects.

Routers are not displayed in the list of stages when using the SDK.


# Import dependencies
from encord import EncordUserClient, Project


SSH_PATH = "<file-path-to-private-key-file>"
PROJECT_HASH = "<unique-id-for-project>"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

# Print all Workflow stages
for idx, stage in enumerate(project.workflow.stages):
    print(f"Stage #{idx}: {stage}")

Consensus Workflow Project This is an example of a Consensus Workflow graph.

Non-Consensus Workflow Projects

In the SDK, a class is defined for every stage type. This allows you to see what properties and actions each stage offers. The following stages are supported for non-Consensus Projects:

AnnotationStage
ReviewStage
FinalStage (Complete and Archive)


class AnnotationStage(WorkflowStage):
	uuid: str
	title: str
  
  def get_tasks()

Tasks provides programmatic access to your tasks available in the UI.
The following tasks are supported for non-Consensus Projects::

assign: Assigns a user to one or more tasks.
submit: Moves a task to the next stage.
release: Releases a task from the current user.

class AnnotationTask:
    uuid: UUID
    data_hash: UUID
    data_title: str
    label_branch: str  # main by default

Display Tasks in a Stage

Use the following scripts as templates for annotation and review tasks.

Consensus Workflow Projects

Consensus annotation tasks can be listed, but cannot be assigned or moved into the Consensus review stage. In Consensus Projects, tasks are broken into subtasks. One subtask for each Annotator. Subtasks can be assigned or submitted. Consensus Workflow Projects support the following stages:

AnnotationStage
ReviewStage
ConsensusAnnotationStage
ConsensusReviewStage
FinalStage (Complete and Archive)

The following actions are supported for Consensus review and Review and Refine:

assign: Assigns a user to one or more tasks.
approve: Moves a task to the next stage.
release: Releases a task from the current user.
reject: Rejects a task.

    label_hashes = [option.label_hash for option in task.options]
    label_rows_for_consensus = project.list_label_rows_v2(label_hashes=label_hashes)

    with project.create_bundle(bundle_size=BUNDLE_SIZE) as label_initialize_bundle:
        # Bundling all our initialization operations in one operation
        for label_row in label_rows_for_consensus:
            label_row.initialise_labels(bundle=label_initialize_bundle)

        target_label_row.initialise_labels(bundle=label_initialize_bundle)

    # Download labels
    for label_row in label_rows_for_consensus:
        # Perform custom user logic and populate the target label row.
        # This means defining produce_result in your custom logic as produce_result
        # is not defined in the Encord SDK.
        if is_consensus := produce_result(label_rows_for_consensus, target_label_row):
            target_label_row.save()
            task.assign("<your-admin@example.com>")

End-to-End Example moving tasks through Projects

This example uses a basic non-Consensus Project Workflow moving a number of tasks from ANNOTATE to COMPLETE. !End-to-end Example Workflow !End-to-end Example tasks

Project ID: 01bd7084-b04a-4cd1-87f3-73e8e78925c4
Data units: apples_01.jpg, apples_02.jpg, apples_03.jpg, apples_04.jpg, apples_05.jpg

Step 1: View all tasks in the Project

A few tasks have been annotated, but they have not been submitted yet. The following code lists all tasks in the ANNOTATE 1 stage.

# Import dependencies
from encord import EncordUserClient, Project

from encord.workflow import(
  AnnotationStage, 
  ReviewStage,
  ConsensusAnnotationStage, 
  ConsensusReviewStage,
  FinalStage
)


SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

stage = project.workflow.get_stage(name="Annotate 1", type_=AnnotationStage)
# type_ is an optional parameter here, any other type narrowing technique can be used here
# for example it can be an assert like follows
assert isinstance(stage, AnnotationStage)

for task in stage.get_tasks():
    
    print(f"Task: {task}")

From the returned results we can see that four of the data units have been assigned (apples_01 to apples_04) while one task has not (apples_05). We do not know the extent that each of the assigned data units has been annotated, but we want the tasks to move through the Workflow.

Step 2: Submit all tasks for review

The following code submits ALL tasks to the REVIEW 1 stage. Before the tasks can be submitted they are first assigned to a user in the Project. The user could be any user capable of annotating in the Project (because this is the ANNOTATE stage). For this example, the Admin of the Project (the user with SDK access) is assigned.

Submit all tasks for review

# Import dependencies
from encord import EncordUserClient, Project

from encord.workflow import(
  AnnotationStage, 
  ReviewStage,
  ConsensusAnnotationStage, 
  ConsensusReviewStage,
  FinalStage
)

SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

stage = project.workflow.get_stage(name="Annotate 1", type_=AnnotationStage)
# type_ is an optional parameter. Any type of narrowing technique can be used here.
# For example:
assert isinstance(stage, AnnotationStage)

BUNDLE_SIZE = 100

with project.create_bundle(bundle_size=BUNDLE_SIZE) as bundle:
    for task in stage.get_tasks():

        task.assign("chris@acme.com")

        task.submit(bundle=bundle)
        
        print(f"Task: {task}")

Step 3: Verify that the tasks are in REVIEW 1

Each time we perform an action, we should verify the action is successful. After submitting the tasks, we can verify that the tasks are now in REVIEW 1.

# Import dependencies
from encord import EncordUserClient, Project

from encord.workflow import(
  AnnotationStage, 
  ReviewStage,
  ConsensusAnnotationStage, 
  ConsensusReviewStage,
  FinalStage
)


SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

stage = project.workflow.get_stage(name="Review 1", type_=ReviewStage)
# type_ is an optional parameter here, any other type narrowing technique can be used here
# for example it can be an assert like follows
assert isinstance(stage, ReviewStage)

for task in stage.get_tasks():
    
    print(f"Task: {task}")

All of the tasks are now in stage REVIEW 1. None of the tasks are assigned to any users.

Step 4: Reject a task

We know that apples-05.jpg does not have any labels, because it was not assigned to any users before we submitted the task. If we REJECT the task, according to the Workflow in the Project, the task returns to the ANNOTATE 1 stage. The following code filters the task in the REVIEW 1 stage based on the task’s data hash, and then rejects the task.

# Import dependencies
from encord import EncordUserClient, Project
from encord.workflow import AnnotationStage, ReviewStage, ConsensusAnnotationStage, ConsensusReviewStage, FinalStage
from uuid import UUID  # Import the UUID function

# Constants
SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

# Create user client
user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

# Get stage
stage = project.workflow.get_stage(name="Review 1", type_=ReviewStage)
# Uncomment the following line for different stage

# Check instance type
assert isinstance(stage, ReviewStage)

data_hashes = ["34571f50-90d1-4681-a58b-1fd08e9f6665"]

BUNDLE_SIZE = 100

with project.create_bundle(bundle_size=BUNDLE_SIZE) as bundle:
    for task in stage.get_tasks(data_hash=data_hashes):

        task.assign("chris@acme.com")

        task.reject(bundle=bundle)

        print(f"Task: {task}")

From what was returned, we can see that only data unit apples_05.jpg was acted upon. To verify that the task is now in ANNOTATE 1, run the following:

# Import dependencies
from encord import EncordUserClient, Project

from encord.workflow import(
  AnnotationStage, 
  ReviewStage,
  ConsensusAnnotationStage, 
  ConsensusReviewStage,
  FinalStage
)


SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

stage = project.workflow.get_stage(name="Annotate 1", type_=AnnotationStage)
# type_ is an optional parameter here, any other type narrowing technique can be used here
# for example it can be an assert like follows
assert isinstance(stage, AnnotationStage)

for task in stage.get_tasks():
    
    print(f"Task: {task}")

Step 5: Approve tasks

There are still four tasks in REVIEW 1. The following code approves the tasks. This moves the tasks to the COMPLETE stage. You could approve all the tasks at once the REVIEW 1 stage, but instead we will filter by data hash and then approve.

# Import dependencies
from encord import EncordUserClient, Project
from encord.workflow import AnnotationStage, ReviewStage, ConsensusAnnotationStage, ConsensusReviewStage, FinalStage
from uuid import UUID  # Import the UUID function

# Constants
SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "01bd7084-b04a-4cd1-87f3-73e8e78925c4"

# Create user client
user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

# Get stage
stage = project.workflow.get_stage(name="Review 1", type_=ReviewStage)
# Uncomment the following line for different stage

# Check instance type
assert isinstance(stage, ReviewStage)

data_hashes = [
    "36b0afd3-6ff8-4201-bf65-35a37f6fe5b5",
    "4dc183ba-4233-4cb1-a940-cb6b2bc38f35",

        task.approve(bundle=bundle)

        print(f"Task: {task}")

Step 6: Verify tasks are COMPLETE

Use the following code to verify that the tasks apples01 to apples_04 are in the COMPLETE stage.

# Import dependencies
from encord import EncordUserClient, Project

from encord.workflow import(
  AnnotationStage, 
  ReviewStage,
  ConsensusAnnotationStage, 
  ConsensusReviewStage,
  FinalStage
)


SSH_PATH = "/Users/chris-encord/sdk-ssh-private-key.txt"
PROJECT_HASH = "09765dc5-08b0-4b32-b37a-e1b932b8b684"

user_client: EncordUserClient = EncordUserClient.create_with_ssh_private_key(
    ssh_private_key_path=SSH_PATH
)

# Get project
project: Project = user_client.get_project(PROJECT_HASH)

stage = project.workflow.get_stage(name="Complete", type_=FinalStage)
# type_ is an optional parameter here, any other type narrowing technique can be used here
# for example it can be an assert like follows
assert isinstance(stage, FinalStage)

for task in stage.get_tasks():
    
    print(f"Task: {task}")

And from what the code returns, the tasks are now in the COMPLETE stage.
