i want to save in db (sql) and array format typing

You can use numpy to convert the array to and from JSON. These are the methods I created.

import numpy
def numpy_to_json(n_array):
    n_list = n_array.tolist()
    j_array = json.dumps(n_list) 
    return j_array

def json_to_numpy(j_data):
    j_array = json.loads(j_data)
    n_array = numpy.array(j_array)
    return n_array

I use numpy_to_json to save the face encoding into a MySQL db using a JSON field, and then json_to_numpy to convert the data back into something that the face_recognition project understands. Also, see http://www.numpy.org/.
