TensorFlow报错：InvalidArgumentError: You must feed a value for placeholder tensor ‘Placeholder_2’ with dtype float

如图：

InvalidArgumentError: You must feed a value for placeholder tensor ‘Placeholder_2’ with dtype float
[[node Placeholder_2 (defined at :40) ]]

分析：sess.run(train_step, feed_dict = {xs: batch_xs, ys: batch_ys}) 中 feed_dict 缺少参数

解决方式：补充 keep_prob:0.5，如下所示：

sess.run(train_step, feed_dict = {xs: batch_xs, ys: batch_ys, keep_prob: 0.5})
