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

    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!

@ltejedor Hi, I've met the same problem. It turned out that I've installed the newer version of libigl, which contains a different function 'igl.random_points_on_mesh'. Hope this helps.
