PYBIND11_MODULE(TORCH_EXTENSION_NAME,m){m.def("forward",&lltm_forward,"LLTM forward");m.def("backward",&lltm_backward,"LLTM backward");} 注意:TORCH_EXTENSION_NAME,torch扩展构建会将其定义为在setup.py脚本中为扩展指定的名称。在本例中,TORCH_EXTENSION_NAME的值为“lltm_cpp”。这是为了避免...

https://pytorch.org/tutorials/advanced/cpp_extension.html#writing-a-c-extension 然而,这教程有一个很致命的问题,按照它的方法用不了,被坑了。所以…先看看作为参考吧。 概述 以NMS模块为例,文件树如下: |project name |---cuda | |---nms_kernel.cu ...
setup( name='mmcv', install_requires=install_requires, # 需要编译的c++/cuda扩展 ext_modules=get_extensions(), # cmdclass 为python setup.py --build_ext命令指定行为 cmdclass={'build_ext': torch.utils.cpp_extension.BuildExtension}) 1.
4、如果上述都不存在,则torch.utils.cpp_extension.CUDA_HOME为None,会使用conda安装的cudatoolkit,其路径为cudart 库文件目录的上级目录(此时可能是通过 conda 安装的 cudatoolkit,一般直接用 conda install cudatoolkit,就是在这里搜索到 cuda 库的)。
ffi=create_extension('_ext.cuda_util', headers=headers, sources=sources, define_macros=defines, relative_to=__file__, with_cuda=with_cuda, extra_objects=extra_objects )if__name__ =='__main__': ffi.build() 第四步:调用cuda模块
编写方法也非常的常规,调用的是CUDAExtension。需要在include_dirs里加上头文件目录,不然会找不到头文件。 cpp端用的是pybind11进行封装: 代码语言:javascript 复制 PYBIND11_MODULE(TORCH_EXTENSION_NAME,m){m.def("torch_launch_add2",&torch_launch_add2,"add2 kernel warpper");} ...
