AttributeError: module 'pymesh' has no attribute "Quaternion"

Hi, Thank you for open sourcing the code. It's a good work.

When running the code, I went into a problem. I ran CUDA_VISIBLE_DEVICES=0 python3 train_ae_ShapeNet-v1.py and got an error.

Traceback (most recent call last):
File "train_ae_ShapeNet-v1.py", line 104, in
TRAIN_DATASET = shapenet_pc_dataset.ShapeNetPartPointsDataset_V1(para_config['point_cloud_dir'], batch_size=para_config['batch_size'], npoint=para_config['point_cloud_shape'][0], shuffle=True, split='trainval', preprocess=False)

I want to know which version of pymesh you are using, or is your pymesh downloaded from GitHub?

Hello, I had the same problem.
try this method to install the pymesh library
https://pymesh.readthedocs.io/en/latest/installation.html

@Condor-G
Oh, thanks. I will give it a try.

I guess it may be caused by the pymesh of different versions, the api may be different in different versions.
Simply try to install the pymesh of different versions, see which one works. :)
