class grandchallenge.components.models.ComponentImage(*args, **kwargs)[source]
Parameters:

Relationship fields:

Parameters:
class GPUTypeChoices(value)
class ImportStatusChoices(value)
property original_repo_tag

The tag of this image in the container repository

save(*args, **kwargs)[source]

Save the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.

class grandchallenge.components.models.ComponentInterface(id, overlay_segments, look_up_table, title, slug, description, default_value, schema, kind, relative_path, store_in_database)[source]
Parameters:

  • id (AutoField) – Primary key: ID

  • overlay_segments (JSONField) – Overlay segments. The schema that defines how categories of values in the overlay images are differentiated. Example usage: [{“name”: “background”, “visible”: true, “voxel_value”: 0},{“name”: “tissue”, “visible”: true, “voxel_value”: 1}]. If a categorical overlay is shown, it is possible to show toggles to change the visibility of the different overlay categories. To do so, configure the categories that should be displayed. For example: [{“name”: “Level 0”, “visible”: false, “voxel_value”: 0].

  • 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.

Relationship fields:

Parameters:

look_up_table (ForeignKey to LookUpTable) – Look up table. The look-up table that is applied when an overlay image is first shown (related name: componentinterface)

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.

Where should the file be located?

Images need special handling as their names are fixed.

class grandchallenge.components.models.InterfaceKindChoices(value)[source]

Interface kind choices.

class grandchallenge.components.models.InterfaceSuperKindChoices(value)[source]
class grandchallenge.components.models.InterfacesAndValues(interfaces, values)[source]
interfaces: set
values: dict
class grandchallenge.components.models.OverlaySegmentsMixin(*args, **kwargs)[source]
Parameters:

overlay_segments (JSONField) – Overlay segments. The schema that defines how categories of values in the overlay images are differentiated. Example usage: [{“name”: “background”, “visible”: true, “voxel_value”: 0},{“name”: “tissue”, “visible”: true, “voxel_value”: 1}]. If a categorical overlay is shown, it is possible to show toggles to change the visibility of the different overlay categories. To do so, configure the categories that should be displayed. For example: [{“name”: “Level 0”, “visible”: false, “voxel_value”: 0].

Relationship fields:

Parameters:

look_up_table (ForeignKey to LookUpTable) – Look up table. The look-up table that is applied when an overlay image is first shown

class grandchallenge.components.models.Tarball(*args, **kwargs)[source]
Parameters:

Relationship fields:

Parameters:
class ImportStatusChoices(value)
save(*args, **kwargs)[source]

Save the current instance. Override this in a subclass if you want to control the saving process.

The ‘force_insert’ and ‘force_update’ parameters can be used to insist that the “save” must be an SQL insert or update (or equivalent for non-SQL backends), respectively. Normally, they should not be set.
