File

Training and fine-tuning models is done elsewhere in the W&B Python SDK. Use the Public API for querying and managing data after it has been logged to W&B.

class File

File saved to W&B.

Represents a single file stored in W&B. Includes access to file metadata. Files are associated with a specific run and can include text files, model weights, datasets, visualizations, and other artifacts. You can download the file, delete the file, and access file properties.

Specify one or more attributes in a dictionary to fine a specific file logged to a specific run. You can search using the following keys:

• id (str): The ID of the run that contains the file
• name (str): Name of the file
• url (str): path to file
• direct_url (str): path to file in the bucket
• sizeBytes (int): size of file in bytes
• md5 (str): md5 of file
• mimetype (str): mimetype of file
• updated_at (str): timestamp of last update
• path_uri (str): path to file in the bucket, currently only available for S3 objects and reference files

Args:

• client: The run object that contains the file
• attrs (dict): A dictionary of attributes that define the file
• run: The run object that contains the file

property File.path_uri

Returns the URI path to the file in the storage bucket.

Returns:

• str: The S3 URI (e.g., ‘s3://bucket/path/to/file’) if the file is stored in S3, the direct URL if it’s a reference file, or an empty string if unavailable.

Returns:

• str: The path_uri property value.

property File.size

Returns the size of the file in bytes.

method File.delete

delete()

Delete the file from the W&B server.

method File.download

download(
    root: 'str' = '.',
    replace: 'bool' = False,
    exist_ok: 'bool' = False,
    api: 'Api | None' = None
) → io.TextIOWrapper

Downloads a file previously saved by a run from the wandb server.

Args:

• root: Local directory to save the file. Defaults to the current working directory (".").
• replace: If True, download will overwrite a local file if it exists. Defaults to False.
• exist_ok: If True, will not raise ValueError if file already exists and will not re-download unless replace=True. Defaults to False.
• api: If specified, the Api instance used to download the file.

Raises: ValueError if file already exists, replace=False and exist_ok=False.
