3. 利用`cudaextension`编写CUDA扩展时,对于复杂的数据结构,如自定义结构体作为内核函数参数,需要先在CPU和GPU代码中正确定义结构体,例如`struct MyData { float value; int index; }; __global__ void process_struct(MyData* data, int n) { int idx = blockIdx.x * blockDim.x + threadIdx.x; if...

Extension of scan to large arrays is discussed in Section 39.2.4.Example 2. A Double-Buffered Version of the Sum Scan from Algorithm 11: for d = 1 to log2 n do 2: for all k in parallel do 3: if k 2 d then 4: x[out][k] = x[in][k –2 d-1] + x[in][k] 5: else...
BuildExtension执行许多必需的配置步骤和检查,并在混合C++/CUDA扩展的情况下处理混合编译。 3.2 Writing the C++ Op <torch/extension.h>是一站式头文件,包含写入C++扩展所需的所有PyTorch操作,包括: ATen库是用于张量计算的主要API, pybind11,是为C++代码创建Python绑定的方式 ...
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: AI检测代码解析 |project name |---cuda
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)。
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.
