运行"OpenPose C++ API Tutorial - Example 3 - Body from image"失败
Running of "OpenPose C++ API Tutorial - Example 3 - Body from image" has failed
我已经成功安装了openpose(使用OpenCV，CUDA和所有必需的库(。起初，我尝试通过运行演示应用程序来运行openpose(我不得不使用参数--net-resolution(：
./build/examples/openpose/openpose.bin --net-resolution "-1x64"
它工作正常。
现在，我想在我自己的源代码中使用openpose。所以我想从OpenPose教程中构建并运行一个示例(03个来自图像的关键点(。但是当我尝试运行源代码时，我得到了以下输出：
Starting OpenPose demo...

你能帮我找出可能出错的地方吗？即使在我设置--net-resolution之前，error == cudaSuccess (2 vs. 0) out of memory显示的消息也通过 openpose 演示应用程序显示。设置此参数后，打开姿势已开始正常工作。
非常感谢您的任何建议，任何帮助或评论都可以引导我解决问题。
现在我几乎感到尴尬。问题不在于禁用一些其他选项或附近的任何东西。问题出在此代码中：
const auto netInputSize = op::flagsToPoint(FLAGS_net_resolution, "-1x368");
就像我写的，我想降低净分辨率，因为我只有 2GB 的 GPU 内存。但是当我复制粘贴的示例代码时，我看到了上面的代码段，我认为这意味着：
const auto netInputSize = op::flagsToPoint(<flag_name>, <flag_value>);
但事实并非如此。经过一些探索和调试，我发现标志FLAGS_net_resolution的值在此代码之前和之后是相同的。我发现如果您想在代码中更改标志的默认值(而不是通过命令行(，则必须在ParseCommandLineFlags()调用函数之前在main()函数中执行此操作(即更改默认标志值(。
所以，我的问题的解决方案是：
- 复制示例源代码
- 将示例源代码粘贴到我的源文件中
- 更改函数
main()中的网络分辨率标志
int main(int argc, char *argv[])
{
FLAGS_net_resolution = "-1x256";
// Parsing command line flags
gflags::ParseCommandLineFlags(&argc, &argv, true);
// Running tutorialApiCpp
return tutorialApiCpp();
}
注意：仅更改了标志net_resolution的默认值，仍然可以通过命令行设置该值。
再次感谢。
