RKNN模型转换问题

您好，目前遇到转换模型的问题：tf 1.14
--> Loading model
E Unknow layer "tensorarraygatherv3"
E Catch exception when loading tensorflow model: /Users/xupeng/models-master/research/object_detection/result/frozen_inference_graph_1104.pb!
T Traceback (most recent call last):

done
这个问题有解决方法吗？谢谢

tf 1.14, 这个算子是不支持吗？训练和转换都是在同一台机器的
