# This file lists node ids (following pytest format) of scikit-learn tests
# that are to be deselected during the test discovery step.
#
# Deselection can be predicated on the version of scikit-learn used.
# Use - node_id cond, or - node_id cond1,cond2  where cond is OPver.
# Supported OPs are >=, <=, ==, !=, >, <
# For example,
#    - tests/test_isotonic.py::test_permutation_invariance >0.18,<=0.19
#  will exclude deselection in versions 0.18.1, and 0.18.2 only.
