Issues running cardiac segmentation example in collab

[haydon1999]

I keep getting this error saying a post processing file is missing for the cardiac segmentation sample.

WARNING! Cannot run postprocessing because the postprocessing file is missing. Make sure to run consolidate_folds in the output folder of the model first! The folder you need to run this in is /home/haydon/.platipy/nnUNet_models/nnUNet/3d_lowres/Task400_OPEN_HEART_1FOLD/nnUNetTrainerV2__nnUNetPlansv2.1

I have tried running the example in collab as well as locally and am getting the same error. Any ideas how to fix this? Thanks so much.
