How to generate ground truth pkl

I have followed the instruction on baseline repo:https://github.com/jagjeet-singh/argoverse-forecasting
When I want to use eval_forecasting_helper.py, it requires groundtruth.pkl file to be used.
Do I have to generate the ground truth pkl file or I miss some steps?
Thanks
