libtorch_cpu.so

[wanglei1006]

Dear yifita,
when I run the cage_deformer_3d.py, the following Error arises.

from .._ext import sampling, linalg

ImportError: libtorch_cpu.so: cannot open shared object file: No such file or directory

I searched for solutions and found that pytorch1.4.0 has no libtorch_cpu.so or libtorch_cuda.so, and it only has libtorch.so.
While this code only works with pytorch1.4.0, I don't know how to solve this problem.
I appreciate your help, thanks a lot!

This could be the issue from having built with a different version of pytorch other than 1.4.0, the build folder in pytorch_points will have reminiscent of the legacy. Hence, try deleing the "build" folder and running python setup.py develop again.

solved this problem on my machine, thanks!
