Keras中的错误:无效的参数'metrics'传递给K.function [英] error in Keras: Invalid argument 'metrics' passed to K.function

问题描述

我正在研究有关机器学习的一些问题，并希望在python中尝试功能强大的软件包Keras(使用Theano后端).当我在此处运行用于数字识别的MLP演示时，它给出以下错误消息:

I am working on some problems about machine learning and want to try the powerful package Keras(using Theano backend) in python. While I am running a demo of MLP for digit recognition here, it gives the follow error message:

Traceback (most recent call last):
File "mlp.py", line 52, in <module>
metrics=['accuracy'])
File "/usr/local/lib/python2.7/dist-packages/keras/models.py", line 564, in compile
updates=updates, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/keras/backend/theano_backend.py", line 459, in function
raise ValueError(msg)
ValueError: Invalid argument 'metrics' passed to K.function

我不知道为什么会显示错误消息，有人可以帮助我修复错误吗?预先谢谢你.

I don't know why it gave the error message, can anyone help me to fix the bug? Thank you in advance.

推荐答案

此错误表示您正在运行Keras版本0(例如0.3.2)，但正在运行为Keras版本1编写的代码.您可以升级到Keras 1 ，或从对model.compile()的函数调用中删除metrics=['accuracy'].

This error means that you are running Keras version 0 (e.g. 0.3.2) but running code that was written for Keras version 1. You can upgrade to Keras 1, or remove metrics=['accuracy'] from the function call to model.compile().
