IOError: Unable to open file (File signature not found)

keras加载模型有两种方式
1.model = load_model('model.h5')
2.
model = Sequential()
model.add(Conv2D(32, (3, 3), padding='same', input_shape=(3, IMG_SIZE, IMG_SIZE), activation='relu'))
model.add(Conv2D(32, (3, 3), activation='relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
# model.add(Dropout(1))
model.add(Conv2D(64, (3, 3), padding='same', activation='relu'))
model.add(Conv2D(64, (3, 3), activation='relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
# model.add(Dropout(1))
model.add(Conv2D(128, (3, 3), padding='same', activation='relu'))
model.add(Conv2D(128, (3, 3), activation='relu'))
model.add(MaxPooling2D(pool_size=(2, 2)))
# model.add(Dropout(1))
model.add(Flatten())
model.add(Dense(512, activation='relu'))
# model.add(Dropout(1))
model.add(Dense(NUM_CLASSES, activation='softmax'))
model.load_weights('model.h5')
adam = Adam(lr=1e-6)
model.compile(loss='mse', optimizer=adam)
又一次加载时报错了，IOError: Unable to open file (File signature not found)

       OSError: Unable to open file (File signature not found)
      
     
   
  

原因：model.h5内容丢失了，大小为59k
重新训练一个正常的model.h5就可以了
