Unable to locate .pb file in custom model

[yolo-pothole]

I have trained my model with a single object 'pothole' and here is the .Pb file https://drive.google.com/file/d/10Y6w9tlHvpKCg-wXcLYhmteN9Va7r6X8/view?usp=sharing .
After making changes in the config file and running it. I am facing this issue.

Caused by: java.io.IOException: Not a valid TensorFlow Graph serialization: NodeDef mentions attr 'explicit_paddings' not in Op<name=Conv2D; signature=input:T, filter:T -> output:T; attr=T:type,allowed=[DT_HALF, DT_BFLOAT16, DT_FLOAT, DT_DOUBLE]; attr=strides:

I tried changing the tensor flow version and running it again but it didnt work.
Can you please resolve it
