Create an Experiment and log to Comet

To add a Comet Experiment to your Project, simply copy and paste the following snippet into the top of your file:

## import comet_ml at the top of your file
from comet_ml import Experiment

## Create an experiment with your api key
experiment = Experiment(
    api_key="Your API Key",
    project_name="Your Project Name",
    workspace="Your Workspace Name",
)
metrics = {'accuracy': 0.9, 'loss': 0.01}
experiment.log_metrics(metrics, step=1)
parameters = {'batch_size': 32, 'learning_rate': 0.0001}
experiment.log_parameters(parameters)

See logged Experiments in the Comet UI
