Annotation download error about objectron

I uploaded it again, it should be good to go.

Hi,

The 404 error is gone! However, I now get this error when my script processes the new annotation file:

myscript.py:38: RuntimeWarning: Unexpected end-group tag: Not all data was converted
  frame_data.ParseFromString(message_buf)
Traceback (most recent call last):
  File "myscript.py", line 83, in <module>
    sequence_geometry = get_geometry_data(geometry_file)
  File "myscript.py", line 41, in get_geometry_data
    transform = np.reshape(frame_data.camera.transform, (4, 4))
  File "<__array_function__ internals>", line 6, in reshape
  File "/home/stsuei/miniconda3/envs/fisher_uncertainty/lib/python3.7/site-packages/numpy/core/fromnumeric.py", line 299, in reshape

    result = getattr(asarray(obj), method)(*args, **kwds)
ValueError: cannot reshape array of size 0 into shape (4,4)

The function get_geometry_data that is failing is copied from the Objectron Geometry Tutorial Jupyter notebook. It does not run into any problems on any of the other files in the batch.

Thank you for your help,
Stephanie

I cannot re-produce this. Could you double-check? (make sure you restart your notebook and delete previous local files perhaps?) Here is what I'm getting from the geometry tutorial notebook:

public_url = "https://storage.googleapis.com/objectron"
video_filename = public_url + "/videos/laptop/batch-39/38/video.MOV"
metadata_filename = public_url + "/videos/laptop/batch-39/38/geometry.pbdata"
annotation_filename = public_url + "/annotations/laptop/batch-39/38.pbdata"

Yes, it was my mistake. I forgot to redownload the video file and the geometry metadata file. Thanks!
