Loading .npz on Pytorch3D Poinclouds structure gives - KeyError: 'verts is not a file in the archive'

Awesome project, thank you so much

KeyError                                  Traceback (most recent call last)

**KeyError: 'verts is not a file in the archive'**

I am creating Pytorch3d datastructure Pointclouds

from pytorch3d.structures import Pointclouds
#import all the others

# Set paths
DATA_DIR = "./data"
obj_filename = os.path.join(DATA_DIR, "/content/drive/My Drive/Datasets/StructureNET/partnethiergeo/chair_geo/173.npz")

# Load point cloud
pointcloud = np.load(obj_filename)
verts = torch.Tensor(pointcloud['verts']).to(device)     
rgb = torch.Tensor(pointcloud['rgb']).to(device)

point_cloud = Pointclouds(points=[verts], features=[rgb])

I was wondering if the file .npz are normal pointclouds or they are different, and why I am receiving that error? any suggestions how to visualize that pointcloud in Colab?
