Problem to run the code

[Nicolas99-9]

I have a problem to run the code, after the first epoch, I call the function env.reset() to start a new one but I have the following error :

WARN: gym.spaces.Box autodetected dtype as <class 'numpy.float32'>. Please provide explicit dtype.

@Nicolas99-9,

1. Seems you have matplotlib 2.1 installed, see: https://github.com/Kismuz/btgym#-current-issues-and-limitations and AttributeError: 'FigureCanvasAgg' object has no attribute 'renderer' / ValueError: Axis limits cannot be NaN or Inf #19
2. Deprecation warnings (not critical) )are due to gym changes made 25.01.18; will sort it out soon.

[Kismuz]

changes been made to remove deprecation warnings, update.
