Python code using only numPy

Given and obtain the pairwise distance matrix , where ,=||||2

def pairwise_dist(x, y):

""" Args: x: N x D numpy array y: M x D numpy array Return: dist: N x M array, where dist2[i, j] is the euclidean distance between x[i, :] and y[j, :] """ raise NotImplementedError

x = np.random.randn(2, 2) y = np.random.randn(3, 2) print("==x==") print(x) print("==y==") print(y) print("==dist==") print(pairwise_dist(x, y))
