RuntimeError: Error compiling objects for extension during installation of kaolin

Hi, I followed the steps provided in README. I create a virtual environment and installed latest version PyTorch. When I execute python setup.py build_ext --inplace or python setup.py install, I encountered the following errors. I have tried both python 3.6 and python 3.7. The results are the same. My cuda version is 10.2, PyTorch is 1.5, NumPy is 1.18, ninja version is 1.10. The OS is Ubuntu 18.04. Thanks for your help!

It would be great to see Kaolin updated to more recent versions of both Python and Pytorch… it’s starting to fall behind in both areas.

I’m looking at using Kaolin on NASA projects, so I’d love to see it continue to be updated, please. 😃

Since there is no official Conda installation for PyTorch 1.4, I rather install PyTorch 1.2. And now I can install kaolin successfully. However, when I tried to import kaolin, I met another error.
