Error python setup.py build_ext --inplace

Hello, I have an issue building the project. This is the command line and the generated error message.

Thanks in advance, Sebastian

I have not tested building this on Windows and I don't have access to a windows machine to debug this on, so I can't be of much help. If you figure out what needs to change to get things to build on windows, I'd happily accept that PR.

I also faced issue in setup.py when building setup.py running build_ext building 'pointnet2._ext' extension gcc -pthread -B /mnt/disks/user/anaconda3/compiler_compat -Wl,--sysroot=/ -Wsign-compare -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -fPIC -I/mnt/disks/user/anaconda3/lib/python3.6/site-packages/torch/lib/include -I/mnt/disks/user/anaconda3/lib/python3.6/site-packages/torch/lib/include/TH -I/mnt/disks/user/anaconda3/lib/python3.6/site-packages/torch/lib/include/THC -I/usr/local/cuda/include -I/mnt/disks/user/anaconda3/include/python3.6m -c pointnet2/_ext-src/src/bindings.cpp -o build/temp.linux-x86_64-3.6/pointnet2/_ext-src/src/bindings.o -O2 -Ipointnet2/_ext-src/include -DTORCH_EXTENSION_NAME=_ext -D_GLIBCXX_USE_CXX11_ABI=0 -std=c++11 cc1plus: warning: command line option ‘-Wstrict-prototypes’ is valid for C/ObjC but not for C++ In file included from pointnet2/_ext-src/src/bindings.cpp:1:0: pointnet2/_ext-src/include/ball_query.h:2:10: fatal error: torch/extension.h: No such file or directory #include <torch/extension.h> ^~~~~~~~~~~~~~~~~~~ compilation terminated. error: command 'gcc' failed with exit status 1

What version of pytorch are you using? master requires pytorch>=1.0. If you are on pytorch>=1.0, then there seems to be an issue with your pytorch install and I'd suggest re-installing.

[sdoerr1]

Any update on this issue? I've been having the same one with pytorch=1.2 and I've already tried resetting up my anaconda environment twice to reset my pytorch installation

[leowang7]

Same issue here with pytorch=1.1, any suggestions?

Same problem pytorch 1.4 build_temp = os.path.dirname(objects[0]) IndexError: list index out of range in msvccompiler.py line 502
