i checked transform.py and it does need mean and SD as normalize_params at IAMImageTransform()

also in utils i found mean and sd 0.5,0.5, should i put this value in inference.py and let it go?

Hi,

Looks like I did not update the inference.py script at some point. I would not use the default mean=0.5 and std=0.5 parameters, but rather the IAM-specific mean and standard deviation, as using normalization parameters different than those used during training can have serious effects on model performance. I will update the script to pass the proper normalization parameters.

Edit: I passed the wrong issue reference, but the last commit should fix the issue.
