How can I user graph_transform with Tensorflow 2?

Question

I trained a object detection model by using Tensorflow 2.2.0 and SSD MobileNet V2 FPNLite 640x640. It is working in my conda enviroment. But I want to use this model with openCV dnn by using readNetFromTensorflow(---.pb,---.pbtxt). So I converted my saved_model.pb to frozen_graph.pb . Now I have to convert this .pb file to ---.pbttxt file to use with opencv dnn. There is a script which name is tf_text_graph_ssd.py . By using this script I can create ---.pbtxt with frozen_graph.pb . But my problem is this tf_text_graph_ssd just working with tensorflow1.x because a library which name is graph_transform. So I am getting error because of this. I tried a lot of things to solve this problem. Can someone help me please.

Here the error:

I am using:

Cuda 10.1 cuDnn 7.6.5 ubuntu 20.04 tensorflow 2.2.0 opencv 4.2.0 gpu Nvidia GTX1650

I can't use tensorflow 1 because I have to use cuda 10.1 because of my gpu card. If I use tensorflow 1, I can't use my gpu because tensorflow 1.15 support cuda 10.0 .
