logs2:Revisit auth on PyDrive

Revisit auth on PyDrive 2018/4/14

• Log 1: what specific output am I working on right now?
  • Reduce frequency of re-auth on pydrive, which is killing my productivity right now.
• Log 2: thinking out loud - e.g. hypotheses about the current problem, what to work on next
  • Read current implementation.
  • Read official documentation.
  • See if there's option to persist auth results.
• Log 3: record of currently ongoing runs along with a short reminder of what question each run is supposed to answer
  • Wait. Found python - Automating pydrive verification process - Stack Overflow. I just realized that even if we store auth info as file. There's no way to download, because we'd need drive access lol!
  • Instead, I'll move the process in the beginning so that I can get one early.
• Log 4: results of runs (TensorBoard graphs, any other significant observations), separated by type of run (e.g. by environment the agent is being trained in)
  • Moved auth logic on the top.
