MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* gnu/packages/machine-learning.scm (python-pot): Update to 0.9.6.
  [source]: Switch to git-fetch (upstream tag).  Update hash.  Remove
  snippet for deleting 'ot/lp/emd_wrap.cpp'—not present in VCS source.
  [arguments]: Add test-flags to skip 'test_entropic_semirelaxed_gromov'
  (TypeError).
  [native-inputs]: Drop python-wheel; add python-pytest and
  python-pytest-cov.
