Components
- class grandchallenge.components.models.ComponentInterface(id, title, slug, description, default_value, schema, kind, relative_path, store_in_database)[source]
- Parameters
id (AutoField) – Id
title (CharField) – Title. Human readable name of this input/output field.
slug (AutoSlugField) – Slug
description (TextField) – Description. Description of this input/output field.
default_value (JSONField) – Default value. Default value for this field, only valid for inputs.
schema (JSONField) – Schema. Additional JSON schema that the values for this interface must satisfy. See https://json-schema.org/. Only Draft 7, 6, 4 or 3 are supported.
kind (CharField) – Kind. What is the type of this interface? Used to validate interface values and connections between components.
relative_path (CharField) – Relative path. The path to the entity that implements this interface relative to the input or output directory.
store_in_database (BooleanField) – Store in database. Should the value be saved in a database field, only valid for outputs.
- exception DoesNotExist
- Kind
alias of
grandchallenge.components.models.InterfaceKindChoices
- exception MultipleObjectsReturned
- clean()[source]
Hook for doing any extra model-wide validation after clean() has been called on every field by self.clean_fields. Any ValidationError raised by this method will not be associated with a particular field; it will have a special-case association with the field defined by NON_FIELD_ERRORS.
- class grandchallenge.components.models.ComponentInterfaceValue(*args, **kwargs)[source]
Encapsulates the value of an interface at a certain point in the graph.
- Parameters
id (BigAutoField) – Id
interface (ForeignKey to
ComponentInterface
) – Interfacevalue (JSONField) – Value
file (FileField) – File
image (ForeignKey to
Image
) – Image
- exception DoesNotExist
- exception MultipleObjectsReturned
- clean()[source]
Hook for doing any extra model-wide validation after clean() has been called on every field by self.clean_fields. Any ValidationError raised by this method will not be associated with a particular field; it will have a special-case association with the field defined by NON_FIELD_ERRORS.
- property decompress
Should the CIV be decompressed?
This is only for legacy support of zip file submission for prediction evaluation. We should not support this anywhere else as it clobbers the input directory.
- image_file
The single image file for this interface
- property input_file
The file to use as component input
- property relative_path
Where should the file be located?
Images need special handling as their names are fixed.
