I added the flake8 commit for the purpose of testing how long it takes for the cache to download (~44s, https://travis-ci.org/QuantEcon/QuantEcon.py/jobs/466303295#L443). It looks like the download size hasn't decreased significantly because the binaries from conda-forge are still fat. I suppose the remaining solution is to use pip. |

By default, conda installs the non-FLOSS version of numpy, which bloats the installation size by 204.4 MB compressed (~600 MB uncompressed). This slows down the cache creation, even though now the
conda installtime has decreased from ~113s to ~11s.See also: conda-forge/numpy-feedstock#84
