Hello, I used

x, y =MNIST.testdata()

and then did this

“x = (x .- mean(x,dims = 2)) / std(x .- mean(x,dims = 2))”

And I get 28*28*10000 Array{Float64, 3}.

But actually I need an Array 784*10000, which means this should be a 2 dimensional array with 10000 entries, each entry is a 1 dimensional array with 784 elements…

what can I do? Thanks in advance!

The x that is read is 28 * 28 * 10000. I’m not entirely sure what you want but perhaps replacing x with reshape( x, 784, 10000 ) right after loading does the trick?

Thanks! It worked!
