New commit may be breaking imports

Newest commit as of writing (Apr 17th 2026), seems to be breaking imports:

Traceback (most recent call last):
  File "/local/path/tartanair_dl.py", line 5, in <module>
    import tartanair as ta
  File "/git/path/tartanairpy/tartanair/__init__.py", line 1, in <module>

ModuleNotFoundError: No module named 'tartanair.image_resampling.mvs_utils.camera_models'

The above trace came after: $ pip install -e . and a similar trace with site-packages instead of the local editable path is produced when the -e switch is omitted from the installation command.

Figured out the issue: needed to additionally run git submodule update --init --recursive, and then the code worked.
