Actually sorry, I realized there were a couple mistakes above. I also found the handler_service.py. I am still running into the same error though. I added only one custom function - predict_fn - and basically copied the original predict function except for the fact that the inputs parameter is now labelled text1. It still produces the same error. For context, inference.py was put in model1.tar.gz under the folder code which is what is in the instructions. My original model, model.tar.gz without the custom inference.py is working fine. The config files are identical. The only difference between the two folders being that the most recent, model1.tar.gz contains code/inference.py
Thanks.
