# FastLabel Python SDK

_If you are using FastLabel prototype, please install version 0.2.2._

## Installation

```bash
$ pip install --upgrade fastlabel
```

> Python version 3.7 or greater is required

## Usage

Configure API Key in environment variable.

```bash
export FASTLABEL_ACCESS_TOKEN="YOUR_ACCESS_TOKEN"
```

Initialize fastlabel client.

```python
import fastlabel
client = fastlabel.Client()
```

## Limitation

API is allowed to call 10000 times per 10 minutes. If you create/delete a large size of tasks, please wait a second for every requests.

## Task

### Image

Supported following project types:

- Image - Bounding Box
- Image - Polygon
- Image - Keypoint
- Image - Line
- Image - Segmentation
- Image - All

#### Create Task

- Create a new task.

```python
task_id = client.create_image_task(
    project="YOUR_PROJECT_SLUG",
    name="sample.jpg",
    file_path="./sample.jpg"
)
```

- Create a new task with pre-defined annotations. (Class should be configured on your project in advance)

```python
task_id = client.create_image_task(
    project="YOUR_PROJECT_SLUG",
    name="sample.jpg",
    file_path="./sample.jpg",
    annotations=[{
        "type": "bbox",
        "value": "annotation-value",
        "attributes": [
            {
                "key": "attribute-key",
                "value": "attribute-value"
            }
        ],
        "points": [
            100,  # top-left x
            100,  # top-left y
            200,  # bottom-right x
            200   # bottom-right y
        ]
    }]
)
```

> Check [examples/create_image_task.py](/examples/create_image_task.py).

#### Find Task

- Find a single task.

```python
task = client.find_image_task(task_id="YOUR_TASK_ID")
```

#### Get Tasks

- Get tasks. (Up to 1000 tasks)

```python
tasks = client.get_image_tasks(project="YOUR_PROJECT_SLUG")
```

- Filter and Get tasks. (Up to 1000 tasks)

```python
tasks = client.get_image_tasks(
    project="YOUR_PROJECT_SLUG",
    status="approved", # status can be 'registered', 'in_progress', 'completed', 'skipped', 'in_review', 'send_backed', 'approved', 'customer_in_review', 'customer_send_backed', 'customer_approved'
    tags=["tag1", "tag2"] # up to 10 tags
)
```

- Get a large size of tasks. (Over 1000 tasks)

```python
import time

# Iterate pages until new tasks are empty.
all_tasks = []
offset = None
while True:
    time.sleep(1)

    tasks = client.get_image_tasks(project="YOUR_PROJECT_SLUG", offset=offset)
    all_tasks.extend(tasks)

    if len(tasks) > 0:
        offset = len(all_tasks)  # Set the offset
    else:
        break
```

### Common

APIs for update and delete are same over all tasks.

#### Update Task

- Update a single task status and tags.

```python
task_id = client.update_task(
    task_id="YOUR_TASK_ID",
    status="approved",
    tags=["tag1", "tag2"]
)
```

#### Delete Task

- Delete a single task.

```python
client.delete_task(task_id="YOUR_TASK_ID")
```

## Converter

### COCO

- Get tasks and convert to [COCO format](https://cocodataset.org/#format-data) (supporting bbox or polygon annotation type).

```python
tasks = client.get_image_tasks(project="YOUR_PROJECT_SLUG")
pprint(client.to_coco(tasks))
```
