Keras ValueError:（'；当前不支持会话中的某些键：%s'；，dict#u键（['；类模式'；]））

我在分析keras模型时发现了这个post错误，它修改了tensorflow库

因此，我从链接中检查了Keras库代码。但是找不到类似于['class_mode']的东西来修改Keras库。接下来，我尝试在重新安装Keras后运行代码，但即使这样也不起作用

我用anaconda进口Kreas，也许我安装错了

有人能提出解决方案吗？

删除class\u mode='classifical'，它运行时

class\u mode不是model.compile的参数，你到底想用它做什么？
