@ucas010 这个就是预训练图像分类模型里做的预处理操作。
我直接用的预训练好的模型，所以follow这个预训练好的模型需要的预处理操作。
当然在i/vqa问题中，不做预处理操作也许更合适，但是这样需要自己预训练一个不需要预处理操作的图像分类模型。

多谢。
我对torch不太熟，但我发现tf训练的模型似乎都没有这个操作啊

早期的Caffe有减均值图像的做法，PyTorch的torchvision里提供的图像分类模型是有我代码里那个预处理操作的，可以看torchvision/models.html#classification。
至于TensorFlow，你可以自己再好好看看相关资料，以实际训练的时候的操作为准。比如我粗略搜了一下，你可以看看这两个文件preprocessing.py和imagenet_preprocessing.py。
我不使用TensorFlow，所以关于TensorFlow的具体细节你可以自己再深入看看。
祝好。
