Problems of the chamfer distance package

[myukzzz]

Dear author：

First of all, thank you very much for sharing the code of your excellent work. However, when compiling chamfer distance in the test phase, I encountered the following error:

undefined symbol: _ZN8pybind116detail11type_casterIN2at6TensorEvE4loadENS_6handleEb

After verification, I found that it seemed to be a problem with the version correspondence between cuda and nvcc. However, when I changed the version, chamfer distance still failed to compile normally and encountered the following error:

ImportError: /home/myk/.local/lib/python3.8/site-packages/chamfer-0.0.0-py3.8-linux-x86_64.egg/chamfer.cpython-38-x86_64-linux-gnu.so: undefined symbol: _ZN3c1015SmallVectorBaseIjE8grow_podEPvmm

I hope you can check the function of the chamfer distance, or provide your nvcc, torch, cuda versions and running results for me to verify, I will be very grateful!

I have solved this problem, but there is still a problem that the trained checkpoint and model dimensions do not match
