CogFlow

Cogflow module sets up a pipeline for handling datasets and machine learning models using multiple plugins. It includes functions for creating, registering, evaluating, and serving models, as well as managing datasets.

Key components include:

Mlflow Plugin: For model tracking, logging, and evaluation. Kubeflow Plugin: For pipeline management and serving models. Dataset Plugin: For dataset registration and management. Model Plugin: For saving model details. Configurations: Constants for configuration like tracking URIs, database credentials, etc.

Key Functions:

Model Management

register_model: Register a new model. log_model: Log a model. load_model: Load a model. delete_registered_model: Delete a registered model. create_registered_model: Create a new registered model. create_model_version: Create a new version of a registered model.

Run Management

start_run: Start a new. end_run: End the current. log_param: Log a parameter to the current run. log_metric: Log a metric to the current run.

Evaluation and Autologging

evaluate: Evaluate a model. autolog: Enable automatic logging of parameters, metrics, and models.

Search and Query

search_registered_models: Search for registered models. search_model_versions: Search for model versions. get_model_latest_version: Get the latest version of a registered model. get_artifact_uri: Get the artifact URI of the current or specified run.

Dataset Management

link_model_to_dataset: Link a model to a dataset. save_dataset_details: Save dataset details. save_model_details_to_db: Save model details to the database.

Pipeline and Component Management

pipeline: Create a new Kubeflow pipeline. create_component_from_func: Create a Kubeflow component from a function. client: Get the Kubeflow client. load_component_from_url: Load a Kubeflow component from a URL.

Model Serving

serve_model_v1: Serve a model using Kubeflow V1. serve_model_v2: Serve a model using Kubeflow V2. get_model_url: Get the URL of a served model. delete_served_model: Delete a served model.

MinIO Operations

create_minio_client: Create a MinIO client. query_endpoint_and_download_file: Query an endpoint and download a file from MinIO. save_to_minio: Save file content to MinIO. delete_from_minio: Delete an object from MinIO.

Dataset Registration

register_dataset: Register a dataset.
