Provides DataModel, which is the base class for data models implemented in the JWST and Roman calibration software.
A few unit tests require downloading (~500MB) data from CRDS. CRDS must be configured for these tests to pass
(see the CRDS User Guide
for more information). Minimally (if not on the stsci vpn where the default path of
/grp/crds/cache is available) you will need to set CRDS_PATH.
export CRDS_PATH=/tmp/crds_cache/jwst_opsThese tests can also be skipped with the no-crds pytest option
pytest --no-crds
