Quick-Start

Using the sample below, we are going to illustrate how to extract the data that we want using the SDK.

Nutrition Facts Label Sample

Sample Code

#
# Install the Python client library by running:
# pip install mindee
#

from mindee import Client, product, AsyncPredictResponse

# Init a new client
mindee_client = Client(api_key="my-api-key")

# Load a file from disk
input_doc = mindee_client.source_from_path("/path/to/the/file.ext")

# Load a file from disk and enqueue it.
result: AsyncPredictResponse = mindee_client.enqueue_and_parse(
    product.NutritionFactsLabelV1,
    input_doc,
)

# Print a brief summary of the parsed data
print(result.document)

Standard Fields

These fields are generic and used in several products.

BaseField

Each prediction object contains a set of fields that inherit from the generic BaseField class. A typical BaseField object will have the following attributes:

  • value (Union[float, str]): corresponds to the field value. Can be None if no value was extracted.

  • confidence (float): the confidence score of the field prediction.

  • bounding_box ([Point, Point, Point, Point]): contains exactly 4 relative vertices (points) coordinates of a right rectangle containing the field in the document.

  • polygon (List[Point]): contains the relative vertices coordinates (Point) of a polygon containing the field in the image.

  • page_id (int): the ID of the page, always None when at document-level.

  • reconstructed (bool): indicates whether an object was reconstructed (not extracted as the API gave it).

A Point simply refers to a list of two numbers ([float, float]).

Aside from the previous attributes, all basic fields have access to a custom __str__ method that can be used to print their value as a string.

AmountField

The amount field AmountField only has one constraint: its value is an Optional[float].

Specific Fields
