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)
