This page provides steps for installing Comet's Python SDK and describes the main objects and tools it provides.
Install the SDK¶
There are several ways to install the Comet Python SDK in your system. The easiest way is using
pip install comet_ml
conda install -c anaconda -c conda-forge -c comet_ml comet_ml
%pip install comet_ml
See further instructions for getting started.
Experiment is the core class of Comet. An Experiment represents a unit of measurable research that defines a single execution of code with some associated data for example training a model on a single set of hyperparameters.

Experiment and related objects in Experiment objects.
Artifact objects live in a Comet Workspace and are identified by their name. Each artifact can have multiple versions, identified by their version string numbers. Typical artifact types could be dataset, image, training-data, validation-data, testing-data, and so on.

The Comet Optimizer is used to dynamically find the best set of hyperparameter values that will minimize or maximize a particular metric. Optimizer provides many benefits over traditional hyperparameter optimizer search services because of its integration with Comet's Experiments. In addition, Comet's hyperparameter search has a powerful architecture for customizing your search or sweep. You can easily switch search algorithms, or perform phased searches.

The Comet installation package contains a collection of CLI utilities:
|comet upload||For uploading offline experiments|
|comet optimize||For easy running of Optimizer scripts in parallel or serial|
|comet python||For injecting |
|comet offline||For exploring offline experiment ZIP files|
|comet check||For checking and debugging your environment|
|comet models||For listing and downloading Registered Models|
|comet init||For creating example scripts from cookiecutter recipes|
