model.load_weights(fname, by_name=True) 延伸二:应对不均衡样本的情况 使用:class_weight,sample_weight 两者的区别为: class_weight—主要针对的上数据不均衡问题,比如:异常检测的二项分类问题,异常数据仅占1%,正常数据占99%; 此时就要设置不同类对loss的影响。 sample_weight—主要解决的是样本质量不同的问...
I found that even for model.load_weights(filename) does not give an error, if new model is different from saved model. Weights loading skips layers that have no weights, so many different models can be compatible with the same set of weights. If any weight could not be loaded, or if ...

classmethod load(fname, mmap=None) Load an object previously saved using save() from a file. Parameters fname (str)– Path to file that contains needed object. mmap (str, optional)– Memory-map option. If the object was saved with large arrays stored separately, you can load these arrays...

To explore the model we are going to use for transfer learning, let’s load the VGG model architecture pre-trained on the ImageNet dataset: vgg_model_withtop = tf.keras.applications.VGG19( include_top=True, weights='imagenet', ) Notice that we’ve set include_top=True, which means we...
