AttributeError: 'ColorVisuals' object has no attribute 'crc'

I tried to use sh command_test.sh to test a trained model, but it reported an error in loading dexnet model, as shown in the following. I would like to inquire if you have any ideas to solve this problem. Thanks very much.

The above exception was the direct cause of the following exception:

so how to solve it, i occur to this either.

[zhaozj89]

Try an old version Python or some packages, I forgot the exact package or maybe python. Basically the version problem.

[Fang-Haoshu]

I reproduce the error at my side and found that it is the trimesh version problem. An older version of trimesh<=3.15.1 fixes this problem.

[Fang-Haoshu]

The official dex models are also updated. Thus you can either use the older version of trimesh, or redownload the dex model from the website.
