我正在尝试将教程“ Build a Convolutional Neural Network using Estimators”的CNN修改为我的数据集,并且不知道如何解决此错误
...输入文件应该很好,因为它们已经过测试并且可以,因为我当前正在另一个CNN上运行它们,但有很大的不同(它工作正常,但我愿意更改它,添加一些诸如“辍学”之类的额外功能)
事实是该错误(我将Spyder用作IDE)完全没有意义。我已经做了一些尝试,以查看错误在哪里,但是我有点困惑了,所以让我们尝试问问你们

我希望有人能启发我该错误在哪里以及如何解决。 此外,我很高兴收到其他任何改进建议。

在实践中,问题在于此估计量非常严格,并且期望具有预定义名称和格式的变量。 即设置期望的名称:
train_data=mydata
train_labels=mylabels
和格式(字典):
x={"x": train_data}
然后运行
