ResNet-50 is a pretrained model that has been trained on a subset of the ImageNet database and that won the ImageNet Large-Scale Visual Recognition Challenge (ILSVRC) competition in 2015. The model is trained on more than a million images, has 177 layers in total, corresponding to a...
根据训练任务的不同，可以通过调整骨干模型来改变网络结构，并且使用预训练权重来进行初始化：1model = smp.Unet('resnet34', encoder_weights='imagenet')也可以改变模型的输出类型：1model = smp.Unet('resnet34', classes=3, activation='softmax')所有的模型都有预训练编码器，因此准备数据的方法必须与进行...
