bqapi cannot load pixels as array from video #6
Description
Calling image.pixels().asarray() on a BQImage which is a video (4 channel) generates the following error:
Traceback (most recent call last):
File "main.py", line 11, in <module>
array = pixels.asarray()
^^^^^^^^^^^^^^^^
File ".../python3.11/site-packages/bqapi/bqclass.py", line 471, in asarray
return tifffile.imread(io.BytesIO(response.content))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File ".../python3.11/site-packages/tifffile/tifffile.py", line 424, in imread
with TiffFile(files, **kwargs_file) as tif:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File ".../python3.11/site-packages/tifffile/tifffile.py", line 1686, in __init__
raise ValueError('invalid TIFF file')
ValueError: invalid TIFF file
Package versions:
- Python 3.11
- bqapi-ucsb 1.0.7
- tifffile 0.14.0
Note: I chose this version of tifffile because it matches the version used in bisqueUCSB. Note that the error persists with latest tifffile version 2025.9.30.
To reproduce, run the following:
import bqapi
session = bqapi.BQSession()
session.init(bisque_url="https://bisque2.ece.ucsb.edu")
# uri = "00-sAWcivf6tPqGUk6FsnEX5i" # aerial (works)
uri = "00-FM84WchNQhjwAGaTaNvvBL" # RGB video (does not work)
image = session.load(uri)
pixels = image.pixels()
array = pixels.asarray()
print(array.shape)The script behaves as intended for the aerial photo commented out above (X, Y, C) but not for the video (X, Y, T, C).
