使用回调函数的model_checkpoint时路径问题:
使用回调函数的model_checkpoint时,如下定义:
trained_models_path = "./trained_models/LeNet_5"
model_names = trained_models_path + '.{epoch:02d}-{acc:2f}.hdf5'
model_checkpoint = ModelCheckpoint(model_names,monitor='loss',verbose=1,save_best_only=True,save_weights_only=False)
会报故障:
KeyError: 'Failed to format this callback filepath: "./trained_models/LeNet_5.{epoch:02d}-{acc:2f}.hdf5". Reason: \'acc\''
查看报故障的文件位置,将缩写补全,即将acc改为accuracy。
