将模型用flask封装，返回json时报错：TypeError: Object of type ‘int32‘ is not JSON serializable
网上搜索出的解决方案：重写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)
TypeError: Object of type 'int32' is not JSON serializable ——已解决
