Visualization and datasets issue

[17353303313]

I'm sorry to bother you again
After the training, how to visualize the ShapeNet completion result？
andI wanted to train with my own datasets，I modify my JSON file in shapenet.json format，I modified my JSON file to shapenet.json and trained it，The error is as follows:
INFO - 2021-08-31 21:33:03,960 - data_loaders - Collecting files of Taxonomy [ID=02691156, Name=leaf]
