pointops_cuda error

[mandalanil]

I have installed everything separately as requirements.txt is not valid anymore. I am facing problem while trying to train the model. please help me to solve it.

I have the same issue

This is a common issue.
Please cd to extensions/pointops and run python setup,py install.

If you have complied it and had error message: undefined symbol: _ZN6caffe26detail37_typeMetaDataInstance_preallocated_32E
Then, please check the pytorch version. I run my experiments using 1.12, a higher version might lead to this problem.

You see, I used pytorch 1.12 cuda 11.6 2080ti to run the code, and cd to extensions/pointops and run python setup,py install, but this error still occurs.
import pointops_cuda

If you cannot compile it, you can use the pre-build wheel. Please refer to https://github.com/yuxumin/PoinTr

pip install "git+https://github.com/erikwijmans/Pointnet2_PyTorch.git#egg=pointnet2_ops&subdirectory=pointnet2_ops_lib"

Another option is to use pure-PyTorch operations to replace the fps and gather KNN operations. You can refer to
