On: Torch7 – Scientific computing for LuaJIT

[smhx]

Someone I met recently said this (in rough words): "When I'm writing rough code in lua, it's completely acceptable to do a couple of for loops here and there without a disaster in speed. With python, this was a complete meltdown"

I'm not saying it all boils down to just this quote, but I thought it was interesting and wanted to replay it here.

This is true, but there are a couple of easy workarounds for it: Cython and scipy.weave

We're making progress on that front with Numba: http://numba.pydata.org
