-thresh command unable to apply

[Panagiotis]

Using this repository for the set of functions it can provide, but i cannot find the generic -thresh 0.25 command that works in the generic repository. The -dont_show works just fine.
Any assist on where can i tweak the threshold value for inference and evaluate my model with a precision recall curve but also being able to see whats the different threshold can give in detection from the generated images ?
