keras 学习笔记(一) ——— model.fit & model.fit_generator
from keras.preprocessing.image import load_img, img_to_array a = load_img(‘1.jpg’) b = img_to_array(a) print (type(a),type(b)) 输出: a type:<class ‘PIL.JpegImagePlugin.JpegImageF…

keras 学习笔记(二) ——— data_generator
每次输出一个batch,基于keras.utils.Sequence Base object for fitting to a sequence of data, such as a dataset. Every Sequence must implement the __getitem__ and the __len__ methods. If you w…

Keras模型拼装
在训练较大网络时, 往往想加载预训练的模型, 但若想在网络结构上做些添补, 可能出现问题一二… 一下是添补的几种情形, 此处以单输出回归任务为例: # 添在末尾: base_model = InceptionV3(weights=’imagenet’, include_top=False) x = base_model.output x = Global…
