max_ent in example/run_sac.py is not used

	parser.add_argument('--ent_alpha', type=float, default=1,
	help='Entropy coefficient.')

max_ent params in the example seems not used.

machina/machina/algos/sac.py

Line 3 in caf2e51

See https://arxiv.org/abs/1801.01290

Furthermore, algo/sac.py refers to https://arxiv.org/pdf/1801.01290.pdf as a reference of algorithm but the algorithm uses temperature adjustment technique not used in the paper. Probably adding https://arxiv.org/pdf/1812.05905.pdf is better.

Thanks.

Thanks for pointing out an unused argument and the correct reference! Could you send PR for these problems, if you'd like?
