ValueError:检查输入时出错:预期input_1具有形状(None，65563)，但数组的形状为(374，65536) [英] ValueError: Error when checking input: expected input_1 to have shape (None, 65563) but got array with shape (374, 65536)

问题描述

我有一个用Keras编写的自动编码器，如下所示.我收到以下错误，并且不确定如何解决，有什么想法吗?

I have an autoencoder written in Keras shown below. I'm getting the following error, and not sure how to solve it, any ideas?

谢谢.

推荐答案

写65563而不是65536可能是造成此问题的错字.

Writing 65563 instead of 65536 might have been a typo causing the issue.
