Hi @"AileenLiao",
I work a lot with custom models on the OAK and wrote this helper function which handles the PyTorch -> blob conversion process.
justincdavis/oakutilsblob/main/examples/blobs/compile*model.py*
That shows a brief example on how you can define the network with a wrapper class. In order to handle multiple inputs have the input_names method return a list. Something like [("left", InputType.U8), ("right", InputType.U8)] would probably work since you said you are passing the left/right cameras (use FP16 if color data is used).
Then when running the network make sure to pass the inputs through two separate links. In the same repo I have some functions which can help set that up.
As for decoding, that part is harder since you have to read the custom networks outputs as raw data and then shape accordingly. There are also some helper functions I have in that error, but all of this was written to make various work tasks easier so it is far from comprehensive and I am sure Luxonis has examples as well.
The mean and scale values are not currently used in the things I have mentioned (since we use primarily computation represented as PyTorch models) so if you need those I would use the blobconverter tool.
