Dear @zeliu98
Thank you for your code.Here I meet a problem:(Could not import _ext module. )while training. (shown as below)

Traceback (most recent call last): File "function/train_s3dis_dist.py", line 24, in <module> from models import build_scene_segmentation File "/home/yeminglang/project/CloserLook3D/pytorch/models/__init__.py", line 1, in <module> from .build import build_classification, build_multi_part_segmentation, build_scene_segmentation File "/home/yeminglang/project/CloserLook3D/pytorch/models/build.py", line 4, in <module> from .backbones import ResNet File "/home/yeminglang/project/CloserLook3D/pytorch/models/backbones/__init__.py", line 1, in <module> from .resnet import ResNet File "/home/yeminglang/project/CloserLook3D/pytorch/models/backbones/resnet.py", line 3, in <module> from ..local_aggregation_operators import LocalAggregation File "/home/yeminglang/project/CloserLook3D/pytorch/models/local_aggregation_operators.py", line 13, in <module> from pt_utils import MaskedQueryAndGroup File "/home/yeminglang/project/CloserLook3D/pytorch/ops/pt_custom_ops/pt_utils.py", line 10, in <module> "Could not import _ext module.\n" ImportError: Could not import _ext module. Please see the setup instructions in the README: https://github.com/erikwijmans/Pointnet2_PyTorch/blob/master/README.rst

Can this problem be solved by
pip install "git+git://github.com/erikwijmans/Pointnet2_PyTorch.git#egg=pointnet2_ops&subdirectory=pointnet2_ops_lib" ?
I have no idea because I can't download this package properly :( ...
Or there is another things going wrong?

python=3.6
pytorch=1.5
cuda=10.1
pillow=6.2.1

Your prompt reply is looking forward!

Best wish!
Your sincere : yeminglang
