we now have a pillow conda package built against a custom build of libjpeg-turbo (and libtiff w/ libjpeg-turbo) in the fastai test channel
I made 3.6 and 3.7 linux builds:
To install:
conda uninstall -y pillow libjpeg-turbo
conda install -c fastai/label/test pillow
This will make your jpeg decompressing much faster (See Performance Improvement Through Faster Software Components).
Note that this is pillow-5.4.0.dev0 build - i.e. don’t use in production w/o testing.
I also uploaded pillow-simd-5.3.0.post0 w/ libjpeg-turbo and built w/ avx2 - only py36.
conda uninstall -y pillow libjpeg-turbo
conda install -c fastai/label/test pillow-simd
note that it’d get overwritten by pillow through update/install of any other package depending on pillow.
