Numpy and Scipy

• mpi
• openmp
• blas
• numpy 1.11 <- I chose this because many pinnings I've seen use numpy 1.11
  • Remember to change the default pinnings.
• numpy 1.15
• scipy

Pillow

• jpeg
• libtiff
• libpng -- won't pass tests on aarch64 libpng 1.6.36 build failure on linux arm64 (Debian and Ubuntu) pnggroup/libpng#266
• freetype
• pillow
  • remove tk dependency from it.

Matplotlib

Have to build version 2.3.3 first because that is what python 2 can install.. Python 2.7 dropped

• kiwisolver
• tornado
• matplotlib

Depend only on numpy and/or scipy

• cytoolz
• pywavelets

Now the fun ones

• scikit-image -- patch out matplotlib
• opencv -- don't link to qt

Machine Learning and stats

• scikit-learn
• pandas
• pytorch ???? need to unvendor more things.

Even more

• sympy
• stan
• pymc3
• pytables
• astropy
• xarray
