AssertionError during custom run with changed camera model

[mattbev]

During the Image Undistortion step of the process, I get the following error when attempting to use the simple pinhole camera model and the same camera parameters used in the demo:

Traceback (most recent call last):
  File "main.py", line 13, in <module>
    dp.process(params)

  File "<path to>/consistent_depth/utils/load_colmap.py", line 116, in cameras_to_intrinsics
    for c in cameras.values()))
AssertionError

All the line throwing the error is checking is if the model is:

assert all(
    (c.model == "SIMPLE_PINHOLE" or c.model == "PINHOLE"
        or c.model == "SIMPLE_RADIAL"
     for c in cameras.values()))

which it seems like I am complying to? my full command is sudo python3 main.py --video_file <path_to_avi> --path <path_to_results> --camera_model "SIMPLE_PINHOLE" --camera_params "1671.770118, 540, 960" --make_video where the video being used in my command is not the same video as the one in the demo. Am I missing something? I know the camera params are probably off for my use case, but I imagine it should run to completion regardless?

turned out to be my mistake: an earlier checkpoint using an incorrect camera model (in the same output directory) was causing issues with the new run. solution was clearing the output directory
