Can you help me write it faster import numpy as np rows a rows v cols 10 15 3 a np arange rows a cols reshape rows a cols v np arange rows v cols reshape rows v cols c 0 for i in range len v D a v i 2 sum axis 1 c D min print c Is there any numpy function that can do this efficiently python Python Difference between every pair of columns of two numpy arrays . Comparing two NumPy arrays determines whether they are equivalent by checking if every element at each corresponding index is the same Method 1 We generally use the operator to compare two NumPy arrays to generate a new array object Call ndarray all with the new array object as ndarray to return True if the two NumPy arrays are equivalent The numpy setdiff1d function is used to find the set difference of two arrays The following is the syntax import numpy as np diff np setdiff1d ar1 ar2 assume unique False It returns a numpy array with the unique values in the first array that are not present in the second array
