glue.lal.Cache

✓ from glue.lal import Cache

✗ from glue import Cache

Cache class moved to glue.lal in version 2.0+

Create a LIGO cache file using GLUE's Cache class.

from glue.lal import Cache cache = Cache() cache.append('H1', 'R', 1126257418, 1126259500, '/path/to/file.gwf') cache.to_segwizard('/tmp/cache.txt')

Debug

Known issues

breakingIn version 2.0+, the top-level 'glue' package was restructured into subpackages like glue.lal, glue.segments, etc. Importing from the old flat namespace will fail.

fix

Use 'from glue.lal import ...' instead of 'from glue import ...'

affects: >=2.0

deprecatedThe 'glue.segmentdb' module is deprecated and may be removed in future versions. Use 'ligo.segments' directly for segment database queries.

fix

Replace 'from glue.segmentdb import *' with 'from ligo.segments import *'

affects: >=3.0

gotchaThe 'Cache' class's 'to_segwizard' method expects Unix-formatted file paths even on Windows. Backslashes will cause parsing errors.

fix

Use forward slashes or os.path.normpath() to convert paths.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'glue.lal'

Trying to import from glue.lal without installing the lscsoft-glue package.

fix

pip install lscsoft-glue

AttributeError: module 'glue' has no attribute 'Cache'

Using old top-level import pattern (from glue import Cache) which no longer works after restructuring.

fix

Use 'from glue.lal import Cache'

ValueError: Cannot parse segment string: 'H1:1126257418-1126259500'

Calling to_segwizard() without proper columns, or mix-up between old and new segment string format.

fix

Ensure each cache entry has 4 columns: observatory, description, start_time, end_time, filename. LIGO channel/duration format is not supported.
