I used the following command to compare core configurations and it was successfully executed.

`rasa train core -c config_1.yml config_2.yml \ -d domain.yml -s stories_folder --out comparison_models --runs 3 \ --percentages 0 5 25 50 70 95`

But, once i try to see the plot graphs to ensure which policy performs best, it performs an error after running the below command

`rasa test core -m comparison_models --stories stories_folder --out comparison_results --evaluate-model-directory`

it seems that there is a problem with your saved models, it doesn’t contain information about trained policy
