將模型用flask封裝，返回json時報錯：TypeError: Object of type ‘int32‘ is not JSON serializable

網上搜尋出的解決方案：重寫json.JSONEncoder

class MyEncoder(json.JSONEncoder):    def default(self, obj):        if isinstance(obj, numpy.integer):            return int(obj)        elif isinstance(obj, numpy.floating):            return float(obj)        elif isinstance(obj, numpy.ndarray):            return obj.tolist()        else:            return super(MyEncoder, self).default(obj)

 

json.dumps(data,cls=MyEncoder)
