What output nodes should I use?

For context, I’m working with Mozilla’s DeepSpeech (version 0.1.0) to transcribe audios into text. I have a checkpoint folder with these files: model.data-00000, model.index, and model.meta

I need to convert the data file to a .pb file (protobuf). I’ve tried all the links in stack overflow, but nothing seems to be working. I’m guessing that maybe I’m getting my output nodes wrong, so is there a way to know what output nodes are relevant? I have over a 100 in the data file and if I convert all of that to .pb, it’ll be 1.5 GB in size. And if I try to transcribe with such a large frozen model, DeepSpeech gives me a “core dumped” error. So is there a way to know what output nodes are relevant?

I’m not sure if my question makes sense as my brain is scrambled from sitting with this for days now.

Please help anyone! And thank you!
