 # cupy
+该仓库克隆自官方仓库，并整合了依赖的第三方依赖
 
+#编译方法
+```sh
+export CUPY_INSTALL_USE_HIP=1
+export ROCM_HOME=/opt/dtk
+export HCC_AMDGPU_TARGET=gfx936
+export CXXFLAGS="-fpermissive"
+export CFLAGS="-fpermissive"
+
+pip install wheel
+pip install fastrlock==0.8.3 numpy==1.26.4
+git clone http://developer.sourcefind.cn/codes/songlinfeng/cupy.git
+
+cd cupy
+python setup.py bdist_wheel
+```
+如果使用dtk-2604以上版本需要修改/opt/dtk/include/thrust/version.h,添加#define THRUST_DEVICE_SYSTEM THRUST_DEVICE_SYSTEM_HIP
+```sh
+#pragma once
+
+#include <thrust/detail/config/config.h>
+#define THRUST_DEVICE_SYSTEM THRUST_DEVICE_SYSTEM_HIP
+#if THRUST_DEVICE_SYSTEM == THRUST_DEVICE_SYSTEM_CUDA
+#include <cuda/version>
+#endif
+```
