where is drop_dataset ?

[QiLi0226]

Hello,

In pGS-CAM/RandLANet/pGSCAM.py, there is an import statement:
from drop_dataset import SemanticKITTI
However, I couldn't find the drop_dataset module in the project. Could you please upload it?

Thank you.

您好，在pGS-CAM/RandLANet/pGSCAM.py 中：from drop_dataset import SemanticKITTI，我好像并未找到 drop_dataset，能麻烦上传一下吗？
