您好,麻烦请问pytorch版的ctpn性能如何,结合crnn,识别一张图片大概需要多长时间,有用到GPU还是在CPU上计算的?
我在用CRNN的时候,发现CPU版的耗时很长,一张身份证图片,crnn得十几秒(32core E5 v3的cpu),不知道是什么原因。
您在实际使用的时候,FPS大概能达到多少?

O(∩_∩)O谢谢

同问,pytorch的ctpn比tf的快吗?不算后面的crnn,ctpn一张图6-10s(CPU,tf)

你好,CTPN pytorch版本比keras(tf backend)版要快1.2倍,在GTX1080上测试的,单独的crnn毫秒级别。每张图像只是ctpn 0.2秒左右,不过跟图像大小,算力,电脑配置等有关
