Don't terminate on warnings

[sebnapi]

This drove me crazy, there are many deprecation warnings with tensorflow and numpy, especially because you don't specify any versions or requirements. This line was the problem:

Gym-Trading-Env/src/gym_trading_env/environments.py

Lines 14 to 15 in 6d7b773

	import warnings
	warnings.filterwarnings("error")

Over night the code stopped working and I have no clue why it worked before. But removing the termination on warning helped run it again.

BTW this didn't work for me so I needed to add warnings.filterwarnings("ignore", category=DeprecationWarning) below

Then it looks like this:

import warnings
warnings.filterwarnings("error")
warnings.filterwarnings("ignore", category=DeprecationWarning)
