about knn_cuda

[lrrll]

hi why i run the bash test_punet.sh, it happen that "no modul named knn_cuda import KNN"? i run this code with cuda9.0 python 3.6 pytorch1.0

You should install knn_cuda by running

pip install --upgrade https://github.com/unlimblue/KNN_CUDA/releases/download/0.2/KNN_CUDA-0.2-py3-none-any.whl

For more details, please refer to this repo, https://github.com/unlimblue/KNN_CUDA

Thanks for pointing out, I will update the installation guideline later.

yes i had resolved, but another problem increasing.
i want know whether it must need cuda 10 and torch 1.2; my environment is cuda 9 and torch 1.1; but it raise the problem like this:
PU-Net_pytorch-master$ python eval.py --gpu 0 --resume logs/punet_baseline/punet
_epoch_99.pth
Namespace(batch_size=8, gpu=0, model='punet', resume='logs/punet_baseline/punet_epoch_99.pth', up_ratio=4, use_bn=False, use_res=False, workers=4)
Traceback (most recent call last):
File "eval.py", line 26, in
from pointnet2 import pointnet2_utils as pn2_utils
File "/home/ouc/l-dataset/PU-Net_pytorch-master/pointnet2/pointnet2_utils.py", line 7, in
import pointnet2_cuda as pointnet2

baidu say it is because the version of cuda is not match torch

Have you complied pointnet2 successfully, by running

cd pointnet2
python setup.py install 

If cuda and pytorch version mis-match, you may need to re-install pytorch following the official document. Refer to this page, https://pytorch.org/get-started/previous-versions/

This repo is tested with torch 1.2, but I think torch 1.1 is ok.

i run this code with cuda10.0 python 3.6 pytorch1.2

I have solve this problem by using Ubuntu
