input shape of carla-v0.ptm

[henry333]

Hi Praveen Palanisamy, your book is great!
actually I was trying to put the model carla-v0.ptm into env "HomoNcomIndePOIntrxMASS3CTWN3-v0" in macad-gym to see its behavior.
I found the obs.shape is (168,168,3) from the env. yet the input shape of the pretrained model is (168,168,6).
I wonder what's the proper inputs the model required, are those two RGB camera, or one RGB camera plus depth camera?
not sure if you still have the model's info, please help to have a look, thanks!
