Cannot import spconv in the 3D-U-Net repo

[NCTU-VRDL]

Hi @liuzhengzhe!,

I have followed all the steps to successfully install the spconv and import it without any problems, including from spconv import spconv_utils. However, I cannot import spconv inside the model repo (3D-U-Net, merge, relation). The error message is shown below.

     15 import numpy as np
---> 16 from spconv import spconv_utils
     17 from spconv.spconv_utils import (non_max_suppression, non_max_suppression_cpu,
     18                                  points_to_voxel_3d_np, rbbox_iou,

ImportError: cannot import name 'spconv_utils' from 'spconv' (/home/jimmy15923/mnt/project_code/One-Thing-One-Click/3D-U-Net/spconv/__init__.py)

And I can import spconv in the upper repo. Should I remove the original spconv after installation? Thank you

Yes, you can replace this folder with your newly built one (in spconv/build/...) NCTU-VRDL ***@***.***> 于2021年10月19日周二 下午3:39写道：

Hi @liuzhengzhe

Thanks for your quick response. I have replaced the original spconv with a newly built one. But libcudart.so.10.1' not found.
Here are the steps

./3D-U-Net$ rm -r spconv
./3D-U-Net$ ln -s /home/jimmy15923/anaconda3/envs/pnt_group/lib/python3.7/site-packages/spconv ./
./3D-U-Net$ python -c 'import spconv'

Did I miss anything else? Thank you!
