Problem with pointnet2_ops

[matthiasjaeger95]

Hello,

i wanna train your network with my own dataset and ran into that error:

It seems like there is a problem with pointnet2_ops extension. I've created the enviroment following your repo. My Cuda Version is 11.4. Could you help me with that?

Thank you in advance.

Hi, it seems that you have compiled the pointnet2_ops extension with cpu version PyTorch. RuntimeError: false INTERNAL ASSERT FAILED at "pointnet2_ops/_ext-src/src/sampling.cpp":83, please report a bug to PyTorch. CPU not supported Please update your PyTorch into a cuda version and try compiling again.

@AllenXiangX ，Hello, I have also encountered this issue. I can confirm that I am using the cuda version of the torch.

[AllenXiangX]

Perhaps some of the tensors or operations are on the cpu. Please try manually specify the gpus before runing the training script as follows: export CUDA_VISIBLE_DEVICES='2' python train.py --config ./configs/pcn_cd1.yaml

[huyanbi]

@AllenXiangX Okay, I'll try

[huyanbi]

@AllenXiangX .hellow,After trying, I found that it didn't solve the problem.

[sjYoondeltar]

I saw the same error message. In my case, I modify the config yaml file. In the config yaml, I can modify train:gpus:[2] to train:gpus:[0] and the error fixed

[w1hao]

I had this problem as well and it has been resolved. You can change the ‘gpu: [2]’ in the yaml file to the graphics card you want to use, my computer only has one GPU, so I changed it to ‘ gpu: [0]’ and the problem was solved!
