Valueerror: Cannot Feed Value Of Shape

I'm new to Tensorflow and trying to programm a CNN with it. Im watching a tutorial and do exactly, 100% same code, and still get an error message at the end, that says: ValueError:

Solution 1:

You define y of size [?, 1] here:

y = tf.placeholder(tf.int32, shape=[None,1], name="y").

Change it to:

y = tf.placeholder(tf.int32, shape=[None,10], name="y")

Note that the shape is changed to [None,10].

Edit:

Set one_hot to False in mnist = input_data.read_data_sets("MNIST_data/", one_hot=True).
