How to check if a numpy array holds a same value?

Question

i want to check if target has the same array of template has.

for example,

#The array of template
[[[162 181   0]
  [ 36  28 237]
  [  0   0   0]
  [100  60  52]
  [ 39 127 255]]

 [[162 181   0]
  [ 36  28 237]
  [  0   0   0]
  [100  60  52]
  [ 39 127 255]]

 [[162 181   0]
  [ 36  28 237]
  [  0   0   0]
  [100  60  52]
  [ 39 127 255]]]

#the array of target
[[[162 181   0]]

 [[162 181   0]]

 [[162 181   0]]]

so if target has the same array returns true

but if target has different value like below

[[[150 181 0]]

[[162 181  0]]

[[162 181  0]]]

it returns False. how would i be able to do so?

thinking of using numpy but i dont know how

@吴慈霆 i attached the array of template and target images — kerz

@mozway i get ValueError: operands could not be broadcast together with shapes (3,5) (3,1,3) — kerz

The template and the target array have different shapes. How do you want to perform the check in that case? Please provide an example. — kmkurn

any(((template[:, i, :] == target).all() for i in range(template.shape[1])))

Maybe there is a more elegant way.
