Error when running "bash train_diffusion.sh"

Hello, this is truly impressive work. I was eager to try it out, but when I executed bash train_diffusion.sh, I came across the following error:

`[rank0]:   File "Step1X-3D/step1x3d_geometry/models/conditional_encoders/label_encoder.py", line 123, in encode_label
[rank0]:     SYMMETRY_TYPE_MAPPING[label["symmetry"]]
[rank0]: TypeError: unhashable type: 'list'`

Thanks in advance for your help.
