Можно ли использовать свойства pom.xml и игнорировать аргументы командной строки?

import numpy as np

# Given axis along which elementwise multiplication with broadcasting 
# is to be performed
given_axis = 1

# Create an array which would be used to reshape 1D array, b to have 
# singleton dimensions except for the given axis where we would put -1 
# signifying to use the entire length of elements along that axis  
dim_array = np.ones((1,a.ndim),int).ravel()
dim_array[given_axis] = -1

# Reshape b with dim_array and perform elementwise multiplication with 
# broadcasting along the singleton dimensions for the final output
b_reshaped = b.reshape(dim_array)
mult_out = a*b_reshaped

In [149]: import numpy as np

In [150]: a = np.random.randint(0,9,(4,2,3))

In [151]: b = np.random.randint(0,9,(2,1)).ravel()

In [152]: whos
Variable   Type       Data/Info
-------------------------------
a          ndarray    4x2x3: 24 elems, type `int32`, 96 bytes
b          ndarray    2: 2 elems, type `int32`, 8 bytes

In [153]: given_axis = 1

Теперь мы хотели бы выполнить поэтапное умножение вдоль given axis = 1. Давайте создадим dim_array:

In [154]: dim_array = np.ones((1,a.ndim),int).ravel()
     ...: dim_array[given_axis] = -1
     ...: 

In [155]: dim_array
Out[155]: array([ 1, -1,  1])

Наконец, измените форму b & amp; выполните элементное умножение:

In [156]: b_reshaped = b.reshape(dim_array)
     ...: mult_out = a*b_reshaped
     ...: 

Еще раз проверьте информацию whos и обратите особое внимание на b_reshaped & amp; mult_out:

In [157]: whos
Variable     Type       Data/Info
---------------------------------
a            ndarray    4x2x3: 24 elems, type `int32`, 96 bytes
b            ndarray    2: 2 elems, type `int32`, 8 bytes
b_reshaped   ndarray    1x2x1: 2 elems, type `int32`, 8 bytes
dim_array    ndarray    3: 3 elems, type `int32`, 12 bytes
given_axis   int        1
mult_out     ndarray    4x2x3: 24 elems, type `int32`, 96 bytes
