GPU版本完全没法跑啊，一个接一个的错误 about 10kinds-light-face-detector-align-recognition HOT 4 OPEN

希望作者有空上传一下能跑通GPU的版本，感谢~

这套程序里，有的算法是基于pytorch框架运行的，有的是调用opencv运行的。在基于Pytorch框架运行的程序里，有device = 'cuda' if torch.cuda.is_available() else 'cpu'这行代码，它会根据运行设备自适应切换到cpu或者gpu环境的，而调用opencv的程序在cpu和gpu环境是通用的

嗯，检测到cuda可用，device是'cuda'，可是跑不通啊，各种错误

比如pfld_mtcnn\detector.py报错如下：

这个错误的原因很简单呀，就是网络结构model转换到gpu环境了，但是输入张量Input没有转换到gpu环境，因此你需要在输入张量Input后加上.to(device)
这是我编写程序的一个疏忽，当初这些网络都是轻量级的，我就在win10-cpu机器上编写程序，没有放在gpu设备上调试，请谅解
