se_seg模块，我看了斯坦福数据集，他有六列数据，后三列是rgb信息，请问，我的数据集没有颜色信息，还能用来训练吗？》

[JohanYe]

Yes? There's an option "normal_channel" for this, just set it to False, and the network will not expect rgb channels

very thanks to you ,guy, i am labeling datasets which are not standard,it's a little difficult,i think ,i can use semantic segmentation to slove my task.

你好，请教下，你看懂作者给的6维的数据集的含义了吗？出来x,y,z后面三个是什么呀。

Your answer is in the title of this issue, lzh1998-lzh says it is RGB colors at each point

Have you finished the semantic segmentation on your own datasets? And how did you labeled datasets and make the same format as the Stanford3dDataset?

@lzh1998-lzh my .las point cloud data only have (x,y,z,lable),How can i make the same format as the Stanford3dDataset? Can I add a QQ to learn from you。thank you!!!! my qq：1002923065

There's an option "normal_channel" for this, just set it to False, and the network will not expect rgb channels。 没有颜色 rgb 信息也可以。

Hello where is the "normal_channel" ?

[anassmu]

it's set by default to false, for part segmentation (pointnet2_part_seg_ssg.py) classifier = MODEL.get_model(NUM_CLASSES,normal_channel=False)
