最近在做MaskRCNN

在自己的數(shù)據(jù)（labelme）轉(zhuǎn)為COCOjson格式遇到問題：TypeError: Object of type 'int64' is not JSON serializable

原因是numpy的數(shù)據(jù)類型不能被json兼容

最簡單的做法是自己寫一個(gè)序列類

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)

　　

it looks like?json?is telling you that an?intisn't serializable, but really, it's telling you that this particular np.int32 (or whatever type you actually have) isn't serializable.

The easiest workaround here is probably to?write your own serializer

?
