ValueError: all the input arrays must have same number of dimensions

[Petro Liashchynskyi]

When I'm trying to test this model with my own images (not MNIST) I get this error:

I load the images via scipy then reshape these to 28 by 28 pixels.

I use batch_size of 32, number of labels is 5

What's going on here, man? What am I doing wrong? 😞
