Improved syntax and usability

[jaywonchung]

Hi,

I forked this repository and read it through, upon which I found numerous less-pythonic/inefficient pieces of code, less-informative object names, and unused arguments and variables. Examples include things like

if condition is True:

for k, v in zip(list(d.keys()), list(d.values())):

var = True if a==b else False

num_steps

which can (and better) be safely replaced with

if condition:

for k, v in d.items():

var = (a==b)

num_inner_steps

I have fixed this repository for my own research, but I figured others may benefit from this too.

Thus I have done the following:

1. Fix less-pythonic syntax
2. Change to more informative variable names
3. Remove unused variables and arguments
4. Add comments and docstrings
5. Remov continue_from_epoch, evalute_on_test_set_only, and gpu_to_use from json config. These are better as commandline arguments.
6. Test proper functionality of
   • experiment config/script generation
   • execution of experiment scripts, including training, saving, continuing, validation, and testing on top_n models

Functionality changes are as follows:

1. Experiment results are now saved in the Experiments folder. This folder is not tracked by git.
2. Python caches and mini-imagenet data are not tracked by git.
3. Training announcements (print, tqdm, ...) are improved.

Happy research!

P.S. Big thanks to @AntreasAntoniou for the sharing such a great repository!
