Error Running Example

Hello! I'm trying to get the code from this paper running, and am getting the following error:

Traceback (most recent call last):
  File "/content/TextDeformer/NeuralJacobianFields/MeshProcessor.py", line 153, in get_centroids
    self.load_centroids()
  File "/content/TextDeformer/NeuralJacobianFields/MeshProcessor.py", line 105, in load_centroids
    self.centroids.points_and_normals = np.load(os.path.join(self.source_dir, "centroids_and_normals.npy"))

    fid = stack.enter_context(open(os_fspath(file), "rb"))

During handling of the above exception, another exception occurred:

Any insights would be helpful, thank you!
