import numpy as np test_list = [1, 10, 100, 1000, 10000, 100000, 1000000, 10000000, 100000000] np_array_test_list = np.array(test_list)

i use this as a test array, add it throw out an error,

`UFuncTypeError Traceback (most recent call last)

2 print("g4: ", g4)

10 index = np.arange(1,array.shape[0]+1) #index per array element

UFuncTypeError: Cannot cast ufunc 'add' output from dtype('float64') to dtype('int32') with casting rule 'same_kind'`

but if i add array = array.astype(float), the error disappered.
