Hey @metaworld to get metrics for a particular model on your project leader board you can use the get_cross_validation_scores method, if you don't specify a metric in the parameter DR will send you all the metrics.
## Here I get my project and use it to get a list of the models in that project
project = dr.Project.get('61825fd1c17009a4ecbf8e72')
models = project.get_models()
## I take the first model in the list
model = models
## Get metrics from the models cross validation score
print(model.get_cross_validation_scores(metric = "R Squared"))
