Network training method, device, computing apparatus and computer storage medium

The present invention discloses a network training method, a network training device, a computing apparatus and a computer storage medium. The network training method is completed through a plurality of times of iteration. The one-time iteration process of the method includes the following steps that: a first sample image and a second sample image are extracted; a second network corresponding to the style of the first sample image is obtained according to a first network and the first sample image; the second network is utilized to generate a third sample image corresponding to the second sample image; the weight parameter of the first network is updated according to loss between the third sample image and the first sample image and loss between the third sample image and the second sample image; and the above training steps are iteratively performed until a predetermined convergence condition is satisfied. According to the network training method provided by the technical schemes of the present invention, the first network applicable to any style image and any content image can be obtained through training; the first network can facilitate the quick obtaining of the corresponding image conversion network; and therefore, the efficiency of image stylization can be improved.
