Description

The Table class used to display and analyze tabular data.

Unlike traditional spreadsheets, Tables support numerous types of data: scalar values, strings, numpy arrays, and most subclasses of wandb.data_types.Media. This means you can embed Images, Video, Audio, and other sorts of rich, annotated media directly in Tables, alongside other traditional scalar values.

This class is the primary class used to generate W&B Tables https://docs.wandb.ai/models/tables

Args:

• columns:
• data:
• rows:
• dataframe:
• dtype:
• optional:
• allow_mixed_types:
• log_mode:

Methods:

add_column

Adds a column of data to the table.

add_computed_columns

Adds one or more computed columns based on existing data.

add_data

Adds a new row of data to the table.

The maximum amount ofrows in a table is determined by wandb.Table.MAX_ARTIFACT_ROWS.

The length of the data should match the length of the table column.

add_row

Deprecated. Use Table.add_data method instead.

captions

cast

Casts a column to a specific data type.

This can be one of the normal python classes, an internal W&B type, or an example object, like an instance of wandb.Image or wandb.Classes.

file_is_set

get_column

Retrieves a column from the table and optionally converts it to a NumPy object.

get_dataframe

Returns a pandas.DataFrame of the table.

get_index

Returns an array of row indexes for use in other tables to create links.

init_from_json

Initialize a WBValue from a JSON blob based on the class that created it.

Looks through all subclasses and tries to match the json obj with the class which created it. It will then call that subclass’ from_json method. Importantly, this function will set the return object’s source_artifact attribute to the passed in source artifact. This is critical for artifact bookkeeping. If you choose to create a wandb.Value via it’s from_json method, make sure to properly set this artifact_source to avoid data duplication.

is_bound

path_is_reference

to_data_array

Convert the object to a list of primitives representing the underlying data.

type_mapping

Return a map from _log_type to subclass. Used to lookup correct types for deserialization.

with_suffix

Get the name with the appropriate suffix.
