"""
A series of speed tests on pytorch LSTMs.
- LSTM is fastest (no surprise)
- When you have to go timestep-by-timestep, LSTMCell is faster than LSTM
- Iterating using chunks is slightly faster than __iter__ or indexing depending on setup

**Results**

My Ubuntu server:
    OS: posix, pytorch version: 0.4.0a0+67bbf58
