Python에서 NumPy 배열을 JSON으로 직렬화하는 방법은 무엇입니까?

<code class="python">import numpy as np
import codecs, json

a = np.arange(10).reshape(2, 5)  # a 2 by 5 array
b = a.tolist()  # nested lists with the same data and indices

file_path = "/path.json"  ## your path variable
json.dump(b, codecs.open(file_path, 'w', encoding='utf-8'),
          separators=(',', ':'),
          sort_keys=True,
          indent=4) ### this saves the array in .json format</code>

<code class="python">obj_text = codecs.open(file_path, 'r', encoding='utf-8').read()
b_new = json.loads(obj_text)
a_new = np.array(b_new)</code>
