How to use Habitat3 to train and evaluate my new transformer based vision language navigation system?

[goodstudent9]

Hi,
Thank you for your fabulous work.
Now I want to do some navigation task simulation about my model.
Instead of baseline you provided in /habitat_baselines, I have my new model who take the pictures and a high level goal and navigate in house. I want to do this simulation on habitat3.
I have looked through the tutorial you provided, but that seems like there is no specific topic to teach us how to place a brandly new model in your Habitat simulator to train and evaluate it. So I am asking for your help.

Thank you so much!
