无法加载带有自定义度量的keras模型
嗨,我想在keras上制作一个超分辨率模型 我指的是 但是在我编译并保存了一个新模型之后,当我加载该模型时,就会出现度量错误无法加载带有自定义度量的keras模型,keras,Keras,嗨,我想在keras上制作一个超分辨率模型 我指的是 但是在我编译并保存了一个新模型之后,当我加载该模型时,就会出现度量错误 Traceback (most recent call last): File "autoencoder2.py", line 56, in <module> load_model("./ani.model") File "/home/simmani91/anaconda2/lib/python2.7/site-packages/ker

有没有办法加载具有PSNR度量的模型
谢谢阅读。用
加载模型(“ani.model”,自定义对象={“PSNRLoss”:PSNRLoss})
加载模型。那么参数呢?
def PSNRLoss(y_true, y_pred):
return -10. * np.log10(K.mean(K.square(y_pred - y_true)))

model = Model(input_img, out)

model.compile(optimizer=adam, loss='mse', metrics=[PSNRLoss])
