所以我对张量流是新的,我的错误是,我在喂养 对train_neural_network(x)x无效的参数。Tensorflow session.run饲料字典机制
我想要做的是4999次迭代,输入一个[1,400]数组是 图片的位值。所以输入4999张照片。我用 scipy.io作为矩阵而不是张量读取图像。
我对如何使用占位符以及我的代码通常有什么问题感到困惑。因为我提供x和y的占位符,不应该输入x到train_neural_network(x)是占位符值吗?

到底是什么你得到的错误?你可以将它添加到你的问题或作为评论? – Steven
你能改变这个“feed_dict = {”为“feed_dict = {”。我不记得间距是否重要。 – Steven
我添加了错误。谢谢! – Djae
