>>> db
array([[[[   48.4473645 ,  -49.42020132,  -59.52442657,  199.95277333,
            131.69291221,  -69.15365214, -155.71041334,   16.42950385]]]])

>>> db_test
array([[[[   48.4473645 ,  -49.42020132,  -59.52442657,  199.95277333,
            131.69291221,  -69.15365214, -155.71041334,   16.42950385]]]])

>>> db == db_test
array([[[[False, False, False, False, False, False, False, False]]]])

It seems that these two arrays are identical, but they aren't. Can you explain me why?

    Try `np.isclose`. Floats often don't test exactly. – hpaulj May 25 '20 at 16:44
  • i get True using np.isclose – walentines44 May 25 '20 at 16:46
