ValidMind Library

The ValidMind Library is a suite of developer tools and methods designed to automate the documentation and validation of your models.

Designed to be model agnostic, the ValidMind Library provides all the standard functionality without requiring you to rewrite any functions as long as your model is built in Python.

With a rich array of documentation tools and test suites, from documenting descriptions of your datasets to testing your models for weak spots and overfit areas, the ValidMind Library helps you automate model documentation by feeding the ValidMind Platform with documentation artifacts and test results.

To install the ValidMind Library:

pip install validmind

To initialize the ValidMind Library, paste the code snippet with the model identifier credentials directly into your development source code, replacing this example with your own:

import validmind as vm

vm.init(
  api_host = "https://api.dev.vm.validmind.ai/api/v1/tracking/tracking",
  api_key = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  api_secret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  project = "<project-identifier>"
)

After you have pasted the code snippet into your development source code and executed the code, the Python Library API will register with ValidMind. You can now use the ValidMind Library to document and test your models, and to upload to the ValidMind Platform.

Arguments

  • model: A trained model or VMModel instance.
  • input_id (str): The input ID for the model (e.g. "my_model"). By default, this will be set to model but if you are passing this model as a test input using some other key than model, then you should set this to the same key.

LogisticRegression and LinearRegression models are converted to sklearn models by extracting the coefficients and intercept from the R model. XGB models are loaded using the xgboost since xgb models saved in .json or .bin format can be loaded directly with either Python or R.

Arguments

  • model_path (str): The path to the R model saved as an RDS or XGB file.
  • input_id (str, optional): The input ID for the model. Defaults to "model".

Gets a TestSuite object for the current project or a specific test suite.

This function provides an interface to retrieve the TestSuite instance for the current project or a specific TestSuite instance identified by test_suite_id. The project Test Suite will contain sections for every section in the project's documentation template and these Test Suite Sections will contain all the tests associated with that template section.

Arguments

  • test_suite_id (str, optional): The test suite name. If not passed, then the project's test suite will be returned. Defaults to None.

These key-value pairs are associated with the currently selected model (inventory model in the ValidMind Platform) and keys can be logged to over time to create a history of the metric. On the ValidMind Platform, these metrics will be used to create plots/visualizations for documentation and dashboards etc.
