function add_files

Logs File in the DataDirectory. Args:
  • file_paths (List[truefoundry.ml.DataDirectoryPath], optional): A list of pairs of (source path, destination path) to add files and folders to the DataDirectory contents. The first member of the pair should be a file or directory path and the second member should be the path inside the artifact contents to upload to.
         E.g. >>> data_directory.add_files(
              ...     file_paths=[
                         truefoundry.ml.DataDirectoryPath("foo.txt", "foo/bar/foo.txt"),
                         truefoundry.ml.DataDirectoryPath("tokenizer/", "foo/tokenizer/"),
                         truefoundry.ml.DataDirectoryPath('bar.text'),
                         ('bar.txt', ),
                         ('foo.txt', 'a/foo.txt')
                      ]
              ... )
         would result in
         .
         └── foo/
             ├── bar/
             │   └── foo.txt
             └── tokenizer/
                 └── # contents of tokenizer/ directory will be uploaded here
Examples: 
import os
import truefoundry.ml as tfm

with open("artifact.txt", "w") as f:
     f.write("hello-world")

client = tfm.get_client()
data_directory = client.get_data_directory_by_fqn(fqn="<data_directory-fqn>")

data_directory.add_files(
     file_paths=[tfm.DataDirectoryPath('artifact.txt', 'a/b/')]
)

​
function download

Download an file or directory to a local directory if applicable, and return a local path for it. Args:
  • download_path: Relative source path to the desired files.
  • path: Absolute path of the local filesystem destination directory to which to download the specified files. This directory must already exist. If unspecified, the files will either be downloaded to a new uniquely-named directory.
  • overwrite: if to overwrite the files at/inside dst_path if they exist
Returns:
  • str: Absolute path of the local filesystem location containing the desired files or folder.
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
data_directory = client.get_data_directory_by_fqn(fqn="<your-artifact-fqn>")
data_directory.download(download_path="<your-desired-download-path>")

​
classmethod from_fqn

Get the DataDirectory to download contents or load them in memory Args:
  • fqn (str): Fully qualified name of the data directory.
Returns:
  • DataDirectory: An DataDirectory instance of the artifact
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
data_directory = tfm.DataDirectory.from_fqn(fqn="<data_directory-fqn>")

​
function list_files

List all the files and folders in the data_directory. Args:
  • path: The path of directory in data_directory, from which the files are to be listed.
Returns:
  • str: Absolute path of the local filesystem location containing the desired files or folder.
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
data_directory = client.get_data_directory_by_fqn(fqn="<your-artifact-fqn>")
files = data_directory.list_files()
for file in files:
     print(file.path)

​
function update

Updates the current instance of the DataDirectory. Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
data_directory = client.get_data_directory_by_fqn(fqn="<your-data_directory-fqn>")
data_directory.description = 'This is the new description'
data_directory.update()
