TypeError: unsupported operand type(s) for -: 'list' and 'list'

Question

I am trying to implement the Naive Gauss and getting the unsupported operand type error on execution. Output:

  execfile(filename, namespace)
  File \"/media         


        

Answer 1

The operations needed to be performed, require numpy arrays either created via

np.array()

or can be converted from list to an array via

np.stack()

As in the above mentioned case, 2 lists are inputted as operands it triggers the error.
