About tensorflow code

[S.R]

Thanks for your code.When I use the code basis tensorflow, I run the file of build.py. I meet some problems as :
g++ -std=c++11 -O2 -shared -o libocnn.so object/*.o -I/home/onefivechen/anaconda3/envs/ocnn/lib/python3.6/site-packages/tensorflow/include -D_GLIBCXX_USE_CXX11_ABI=0 -I../../octree/octree -I /usr/local/cuda-10.0/include -L /usr/local/cuda-10.0/lib64 -D GOOGLE_CUDA=1 -L/home/onefivechen/anaconda3/envs/ocnn/lib/python3.6/site-packages/tensorflow -l:libtensorflow_framework.so.1 -L../../octree/build -loctree_lib -lrply -fPIC -lcudart
/usr/bin/ld: cannot find -loctree_lib
/usr/bin/ld: cannot find -lrply
collect2: error: ld returned 1 exit status
Makefile:22: recipe for target 'libocnn.so' failed
make: *** [libocnn.so] Error 1

Could you please tell me what environment do the code need?
I use python3.6 cuda10.0 and tensorflow-gpu14.0

This seems to be missing some files. octree_lib? ocnn.so? rply?

I have updated the readme. You can follow the instructions to build the code.

After cmake, I meet some problems:

/home/onefivechen/Desktop/O-CNN-tf/octree/octree/math_functions.cpp: In function ‘void bounding_sphere(float&, float*, const float*, int)’:

Do you konw how to solve it?

I found that there is no file called Miniball.hpp in the octree. And I also find it in folder external, but is is an empty file. Do you miss it?
I also find there is no file called nanoflann.hpp

[S.R]

solve it
