❓ Questions and Help

I am using the stable release v0.1.7 for Habitat-Sim and Habitat-Lab, and I am going through this tutorial: https://github.com/facebookresearch/habitat-lab/blob/v0.1.7/examples/tutorials/nb_python/Habitat_Interactive_Tasks.py. But, I get this error:

Traceback (most recent call last):
  File "examples/tutorials/nb_python/Habitat_Interactive_Tasks.py", line 753, in <module>
    sim, "rgb", crosshair_pos=[128, 190], max_distance=2.0
  File "examples/tutorials/nb_python/Habitat_Interactive_Tasks.py", line 706, in raycast
    render_camera = sim._sensors[sensor_name]._sensor_object.render_camera
AttributeError: 'habitat_sim._ext.habitat_sim_bindings.CameraSensor' object has no attribute 'render_camera'

Could you please help me fix it?

Huh, looks like we tagged the wrong thing for 0.1.7. bdd94e31eaa6f28036e92456b3ad3772a283b871 should have been what was tagged. @mathfac can we retag it?

@erikwijmans, the issue is that bdd94e31eaa6f28036e92456b3ad3772a283b871 doesn't have the version bump.

When I remove render_camera = sim._sensors[sensor_name]._sensor_object.render_camera with:

visual_sensor = sim._sensors[sensor_name]
scene_graph = sim.get_active_scene_graph()
scene_graph.set_default_render_camera_parameters(visual_sensor._sensor_object)
render_camera = scene_graph.get_default_render_camera()

I do not get any error, but the agent does not learn the task. Could you please help me fix this issue?

@gtatiya are you using bdd94e3 commit? Otherwise I would advice to use that commit.

Hi @gtatiya, have you managed to resolve the Issue? Have you tried using commit suggested by Oleksandr (https://github.com/facebookresearch/habitat-lab/commit/bdd94e31eaa6f28036e92456b3ad3772a283b871)?
