I have two numpy arrays of shape:
x.shape # (50000, 784)
y.shape # (50000,)
Why can't I use:
X_y = np.hstack([X, y])
My desired outcome is to add y as another column to X
X_y.shape # (50000, 785)

`X_y = np.column_stack([X, y])` – cs95 May 19 '18 at 02:14

`y` needs to be 2d like `x`, e.g. (50000,1) shape. `np.concatenate((x, y[:,None]), axis=-1)`. – hpaulj May 19 '18 at 02:24
