5 years ago torch.utils.cpp_extension is for C++ to create extension.
However, nms module is written in C code here.
So it doesn't work that you just replace create_extension to BuildExtension when import packages.
You need rewrite the nms.c to C++ code if you want use the cpp_extension and you can refer the whole procedure that rewrote C code with C++ extensions like pytorch/audio/commit/18c01be.
Or just use pytorch 0.4.x instead : )
I changed the lib/nms/build.py as:
import os import torch
from torch.utils.ffi import create_extension
from torch.utils.cpp_extension import BuildExtension
sources = ['src/nms.c'] headers = ['src/nms.h'] defines = [] with_cuda = False
if torch.cuda.is_available(): print('Including CUDA code.') sources += ['src/nms_cuda.c'] headers += ['src/nms_cuda.h'] defines += [('WITH_CUDA', None)] with_cuda = True
this_file = os.path.dirname(os.path.realpath(file)) print(this_file) extra_objects = ['src/cuda/nms_kernel.cu.o'] extra_objects = [os.path.join(this_file, fname) for fname in extra_objects]
BuildExtension
create_extension
ffi = BuildExtension( '_ext.nms', headers=headers, sources=sources, define_macros=defines, relative_to=file, with_cuda=with_cuda, extra_objects=extra_objects )
if name == 'main': ffi.build()
But the Errors are:
