packages are to be removed:
- pykalman
- preprocessing
- hmmlearn
- gplearn
- geoplot
- polyglot
- ggplot
- descartes
- fitter
- imagecodecs
- wfdb
- hpsklearn
- cleverhans
- osmnx
- pysal
- wordsegment
- vowpalwabbit
- feather
- kmodes
- ortools
- mlens
- vecstack
- Geohash
- geoviews
- s2sphere
- flashtext
- kmapper
- stemming
- hunspell
- spectral
- essentia
- hypertools
- stop_words
- scattertext
- vaex
- blake3
- catalyst (note no longer maintained since 2022)
