print('OpenCL available:', cv2.ocl.haveOpenCL()) 返回True即为支持openCL,而如果项目中报错"cv::ocl::OpenCLAllocator::upload",这是因为当前版本的openCL与显卡驱动或者说cuda不兼容,所以安全起见,可以设置cv2.ocl.setUseOpenCL(False)。 另外,在GPU enabled OpenCV in Python中,写了一个例子: """ cpu...
We can create more complex patterns by using different characters and varying their positions. Let’s create a diamond pattern using the ‘*’ character: size=5foriinrange(size):forjinrange(size-i):print(' ',end='')forkinrange(2*i+1):print('*',end='')print()foriinrange(size-2,-...
