how to pad NumPy arrays that don't have the same shape with zeros
Help · 6 Jul 2022, 08:59 · 3
I have a set of NumPy arrays in a list and some of the NumPy arrays don't have the same shape as their other members. I will like to pad them with zeros. Does anyone know how I can achieve this? Thank you
ValueError: could not broadcast input array from the shape (558,10) into shape (558,)
I suppose you want to fill the 9 next columns of zeros.
X = X.reshape((-1, 1))
padding = np.zeros((558, 9))
X = np.hstack((X, padding))
Thank you @ff
You're welcome!
