Partial list of functions that use legacy seed or random_state behavior. Per SPEC 7, we're changing the keyword to rng.

Generated mostly by searching for check_random_state. Feel to add to this if I missed anything.

Boxes are checked when the transition_to_rng decorator has been applied. After two releases, we will enable warning messages, and in two more releases, we'll remove the decorator.

• scipy.cluster

  • kmeans API: cluster: transition to rng (SPEC 7) #21878
  • kmeans2 API: cluster: transition to rng (SPEC 7) #21878

• scipy.integrate

  • qmc_quad Doesn't actually accept PRNG directly. Just need to ensure that qmc.check_random_state deprecates use of RandomState.

  • scipy.spatial.distance.directed_hausdorff (API: spatial.directed_hausdorff: transition to 'rng' keyword (SPEC 7) #21913)

  • permutation_test (API: stats._resampling: transition to rng (SPEC 7) #21854, can remove dead code in _pairings_permutations_gen once only Generators are accepted)

  • multiscale_graphcorr (legacy)

• scipy.stats (these need special care because the seed argument works differently than the rest of stats - probably can just add DeprecationWarning about RandomState in qmc.check_random_state)

Checklist for PRs:

• Applies the _transition_to_rng decorator
  • Passes correct old_name to decorator factory
  • Passes correct position_num to decorator factory
• replaces old keyword in signature with rng
• replaces documentation of old keyword with final documentation recommended by SPEC 7
• replaces most uses of old keyword in tests / other functions with rng / Generator
• notes remaining uses of old keyword (left to test backward compatibility during transition)
• check that decorator has replaced documentation correctly
