Change prediction score_threshold and merge_threshold during rastervision predict using pipeline

[aerotractjack]

Hello, I am using the RV pipeline for my object detection task and have encountered an issue. It is not a bug but maybe a feature to implement in the future.

You can view my config in this repo
Python 3.9
PopOS 22.04

When using a model with the pipeline, you have to set the prediction options, merge_thresh and score_thresh before training. Once training finishes and its time to predict, I can't find a way of modifying the pipeline to use a different value for my score_thresh. I am currently predicting via the CLI like rastervision predict ..., but looked into the Predictor class and didn't see anything that would allow me to do this there either. My only idea for now is to modify the pipeline config, but trying that once led to a file unreadable error. Is this possible with my current setup?

Sorry for the very late reply. Yes, you are right that there is no way to do this using the predict CLI command. It should be safe to manually edit the pipeline config though, as long as you don't mess up the JSON format.

Another workaround is to modify your get_config() to add the new scenes you want to predict on to the validation or test set in your DatasetConfig, then modify those params, and then run only the predict stage of the pipeline like so:

rastervision run inprocess "your_config_file.py" predict
