In my dataset each object is represented by a 28x28 dimensional image in a single 'flattened' 784 dimensional vector with an associated label ( 1 or -1). I want to find the number of -1 and 1 labelled images.

I have tried,

In :: data2.min(), data2.max()

But it gives me the output of

Out :: (0.0, 255.0)

which is the Image id, not labels.

These are the image pixels colors, you won't find the labels there. If it is a familiar dataset it should have an associated labels file or a CSV file with the last column as a label.
