【问题描述】：

我的操作系统是 Ubuntu。

我在运行 keras 模型时收到此错误消息。

我已经搜索了一些解决方案，但它们不起作用。例如，我尝试了这篇文章中提到的解决方案： How to fix Python ValueError:bad marshal data?

【解决方案1】：

我在debian 9上安装python3.7时遇到了同样的错误，原来是python3.5，然后我就遇到了这个错误。我通过根据此页面更新 setuptools 来修复它：

pip3 install -U setuptools

当我在从事 Udacity 自动驾驶项目（行为克隆）时，我遇到了与上述相同的问题。 model.h5是python 3.6.3生成的，但是我的python版本是2.7，换成python 3.6.3后就OK了。希望对你有帮助。
