Describe the problem

I am trying to test the ego-motion predictions by your trained model on the KITTI dataset. currently inference.py produces only depth estimations. can you instruct me on the needed modifications to be able to predict egomotion?
thanks!!

You can get egomotion predictions by passing a mode argument to the inference method:

inference_model.inference(inputs, sess, mode='egomotion')

Note that here inputs should be an image containing 3 frames, as defined here:

models/research/vid2depth/model.py
