module model.py

​
function calculate_model_size

Tells about the size of the model Args:
  • model_dir (str): directory in which model is present.
Returns:
total size of the model

​
class ModelVersion

​
property created_at

Get the time at which model version was created

​
property created_by

Get the information about who created the model version

​
property description

Get description of the model

​
property fqn

Get fqn of the current model version

​
property metadata

Get metadata for the current model

​
property metrics

get the metrics for the current version of the model

​
property model_fqn

Get fqn of the model

​
property model_schema

get the model schema for current model

​
property name

Get the name of the model

​
property step

Get the step in which model was created

​
property updated_at

Get the information about when the model version was updated

​
property version

Get version information of the model

​
function delete

Deletes the current instance of the ModelVersion hence deleting the current version. Returns:
True if model was deleted successfully Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
model_version = client.get_model_version_by_fqn(fqn="<your-model-fqn>")
model_version.delete()

​
function download

Download a model file or directory to a local directory if applicable, and return a local path for it. Args:
  • path (str): Absolute path of the local filesystem destination directory to download the specified models. This directory must already exist. If unspecified, the models will either be downloaded to a new uniquely-named directory on the local filesystem or returned directly in the case of the Local ModelRepository.
  • overwrite (bool): If True it will overwrite the file if it is already present in the download directory else it will throw an error
Returns:
  • ModelVersionDownloadInfo: Download Info instance containing model_dir (path to downloaded model folder) and other metadata
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
model_version = client.get_model_version_by_fqn(fqn="<your-model-fqn>")
download_info = model_version.download(path="<your-desired-download-path>")
print(download_info.model_dir)

​
classmethod from_fqn

Get the version of a model to download contents or load them in memory Args:
  • fqn (str): Fully qualified name of the model version.
Returns:
  • ModelVersion: An ModelVersion instance of the Model
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
model_version = tfm.ModelVersion.from_fqn(fqn="<your-model-fqn>")

​
function raw_download

Download a model file or directory to a local directory if applicable, and return a local path for it. Args:
  • path (str): Absolute path of the local filesystem destination directory to download the specified models. This directory must already exist. If unspecified, the models will either be downloaded to a new uniquely-named directory on the local filesystem or returned directly in the case of the Local ModelRepository.
  • overwrite (bool): If True it will overwrite the file if it is already present in the download directory else it will throw an error
Returns:
  • path: Absolute path of the local filesystem location containing the desired models.
Examples: 
import truefoundry.ml as tfm

client = tfm.get_client()
model_version = client.get_model_version_by_fqn(fqn="<your-model-fqn>")
model_version.raw_download(path="<your-desired-download-path>")

​
function update

Updates the current instance of the ModelVersion hence updating the current version. Examples: 
import truefoundry.ml as tfm

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