If you have already used another dynamic, imperative language, you can probably learn enough Lua to use Torch effectively in 30 minutes. Seriously, there are three features in the Lua language which are not trivial: metatables, coroutines and _ENV. None of those are needed to use Torch. It will take more time to learn Torch-specific APIs, but the same problem exists with the other ML frameworks.
