Optional parameters and filters

Parameters

When you export data rows from a project, a model run, or Catalog, you can set parameters to include optional fields in the exports. The table below expresses the parameters that are available for each type of export.

ParameterProject exportModel run exportDataset export (Catalog)Slice export (Catalog)
attachments
metadata_fields
data_row_details
project_details-
label_details-
performance_details-
interpolated_frames
predictions---
project_ids--
model_run_ids--

For explanations of each field and subfield, see Export v2 glossary. For a detailed explanation of the project_ids and model_run_ids parameters, see Export data rows from Catalog below.

To learn how to apply these filters, see the below sections specific to each export type.

Filters

You can use filters to select a subset of data rows to export. The table below contains the filters that are supported for each type of export. You can apply multiple supported filters to the same export. Combinations of filters apply AND operator logic.

FilterProject exportModel run exportDataset export (Catalog)Slice export (Catalog)
last_activity_at--
label_created_at--
workflow_status---
global_keys--
data_row_ids--

The last_activity_at and label_created_at filters take the structure of [<start_date>, <end_date>] and can have the following formats:

  • YYYY-MM-DD
  • YYYY-MM-DD hh:mm:ss
  • YYYY-MM-DDThh:mm:ss±hhmm (ISO 8601)
  • None

The ISO 8601 format allows you to specify the timezone, while the other two formats assume the timezone from the user's workspace settings.

Last activity at

The last_activity_at filter captures only the data rows where the following attributes have been created or modified in the specified time frame:

  • Labels associated with the data row
  • Metadata
  • Data row status within a project
  • Issues or comments on labels associated with the data row

Label created at

The label_created_at filter captures only the data rows where labels have been submitted in the specified time frame.

Workflow status

The workflow_status filter allows you to export only the data rows in a specific status of a project's workflow. The filter accepts the following values:

  • ToLabel
  • InReview
  • InRework
  • Done

This filter only accepts one value. For example, filters = {"workflow_status": "InReview"}.

Global keys

The global_keys filter allows you to export only the data rows with the specified global keys within a project or dataset. This filter accepts a list containing up to 2,000 values. For example, filters = {"global_keys": ["global_key_1", "global_key_2"]}.

Data row IDs

The data_row_ids filter allows you to export only the data rows with the specified IDs within a project or dataset. This filter accepts a list containing up to 2,000 values. For example, filters = {"data_row_ids": ["data_row_id_1", "data_row_id_2"]}.

See the below sections specific to each export type for contextual examples of how to apply these filters.

Export data rows from a project

When you export data rows from a project, you can narrow down your data rows by label status, metadata, batch, annotations, and workflow history. Then, when you export from a project, you may choose to include or exclude certain attributes in your export.

Please note that export_v2 is not supported for projects that use a custom editor.

See the table at the top of this page to find the JSON export formats for each data type.

# Set the export params to include/exclude certain fields. Make sure each of these fields are correctly grabbed 
export_params= {
  "attachments": True,
  "metadata_fields": True,
  "data_row_details": True,
  "project_details": True,
  "label_details": True,
  "performance_details": True
}

# You can set the range for last_activity_at and label_created_at. You can also set a list of data 
# row ids to export. 
# For context, last_activity_at captures the creation and modification of labels, metadata, status, comments and reviews.

# Note: Combinations of filters apply AND logic.
filters= {
  "last_activity_at": ["2000-01-01 00:00:00", "2050-01-01 00:00:00"],
  "label_created_at": ["2000-01-01 00:00:00", "2050-01-01 00:00:00"],
  "workflow_status": "InReview",
  "data_row_ids": ["data_row_id_1", "data_row_id_2"],
  "global_keys": ["global_key_1", "global_key_2"]
}

export_task = project.export_v2(params=export_params, filters=filters)
export_task.wait_till_done()

if export_task.errors:
  print(export_task.errors)

export_json = export_task.result
print("results: ", export_json)
labels = project.label_generator()

## Alternatively you can specify date range to export desired labels from a project
labels = project.label_generator(start="2020-01-01", end="2020-01-02")

for label in labels:
  print(label.annotations)

Export data rows from Catalog

You can export data rows and all their information from a Dataset or a Catalog Slice.

When exporting from Catalog, you can include information about a data row from all projects and model runs to which it belongs. Specifically, for the selected data rows, you can export the labels from multiple projects and/or the predictions from multiple model runs.

As shown below, the project_ids and model_run_ids parameters accept a list of IDs.

See the table at the top of this page to find the JSON export formats for each data type.

Export from a dataset

# Set the export params to include/exclude certain fields. Make sure each of these fields are correctly grabbed 
export_params= {
    "attachments": True,
    "metadata_fields": True,
    "data_row_details": True,
    "project_details": True,
  	"label_details": True,
    "performance_details": True,
    "project_ids": ["<project_id_1>", "<project_id_2>"],
    "model_run_ids": ["<model_run_id_1>", "<model_run_id_2>"]
}

# You can set the range for last_activity_at
# For context, last_activity_at captures the creation and modification of labels, metadata, status, comments and reviews.
# Note: This is an AND logic between the filters, so usually using one filter is sufficient.

filters= {
  "last_activity_at": ["2000-01-01 00:00:00", "2050-01-01 00:00:00"]
}

dataset = client.get_dataset("<dataset_id>")
export_task = dataset.export_v2(params=export_params, filters=filters)
export_task.wait_till_done()
if export_task.errors:
  print(export_task.errors)
export_json = export_task.result
print("results: ", export_json)

Export a list of selected data rows from a dataset

# Set the export params to include/exclude certain fields. Make sure each of these fields are correctly grabbed 
export_params= {
    "attachments": True,
    "metadata_fields": True,
    "data_row_details": True,
    "project_details": True,
  	"label_details": True,
    "performance_details": True,
    "project_ids": ["<project_id_1>", "<project_id_2>"],
    "model_run_ids": ["<model_run_id_1>", "<model_run_id_2>"]
}

# Put the selected data rows into a filter, then it will only export those data rows
filters= {
  "data_row_ids": ["data_row_id_1", "data_row_id_2"],
  "global_keys": ["global_key_1", "global_key_2"]
}

export_task = dataset.export_v2(params=export_params, filters=filters)
export_task.wait_till_done()
if export_task.errors:
  print(export_task.errors)
export_json = export_task.result
print("results: ", export_json)

Export from a slice

# Set the export params to include/exclude certain fields. Make sure each of these fields are correctly grabbed 
export_params= {
    "attachments": True,
    "metadata_fields": True,
    "data_row_details": True,
    "project_details": True,
  	"label_details": True,
    "performance_details": True,
    "project_ids": ["<project_id_1>", "<project_id_2>"],
    "model_run_ids": ["<model_run_id_1>", "<model_run_id_2>"]
}

catalog_slice = client.get_catalog_slice("<slice_id>")
export_task = catalog_slice.export_v2(params=export_params)
export_task.wait_till_done()
if export_task.errors:
  print(export_task.errors)
export_json = export_task.result
print("results: ", export_json)

Export data rows from a model run

Export V2 is the recommended format. See Export from model runs for more details.

See the table at the top of this page to find the JSON export formats for each data type.

# Set the export params to include/exclude certain fields. Make sure each of these fields are correctly grabbed 
export_params= {
    "attachments": True,
    "metadata_fields": True,
    "data_row_details": True
}

export_task = model_run.export_v2(params=export_params)
export_task.wait_till_done()
print(export_task.errors)
export_json = export_task.result
# Turn on the experimental mode of the SDK
client.enable_experimental=True

# If download=False, this returns the URLs of the data files associated with this ModelRun’s labels.
download = False
model_run.export_labels(download=download)
# If download=True, this instead returns the contents as NDJSON format.
download = True
model_run.export_labels(download=download)
