A new question about installing the Pointnet++

[AceSilent]

When I run the command:sudo python setup.py build_ext --inplace

feedback is as follows:

Any help is much appreciated:)

Hi, I added requirements.txt. Please try to use pip install -r requirements.txt to setup an environment consistent with mine before installing PointNet++.

[AceSilent]

thank you for your reply！ I built PointNet as you configured it, and unfortunately it didn't work out. However, I cloned a code from GIt and used CUDA11.2 and pytorch1.8. After modifying some code, I could run it successfully. (but the previously used code still doesn't work) Very strange phenomenon,I don't use a virtual Python environment. thank you for your reply！：）

[kninad]

@AceSilent Could you share which changes to the code were required? That would help me out as well!

Hey, Could you share the code you changed to make it work?

Thanks!

@AceSilent Could you share which changes to the code were required? That would help me out as well!

1. Change "AT_CHECK" to "TORCH_CHECK" in all CPP.h files.

2. Change "type().is_cuda()" to "is_cuda()" in all CPP.h files.

3. Change ".data<float/int>()" to ".data_ptr<float/int>()" in all CPP.h files.
