running setting_up_environment_full raise an error

[djoffrey]

Hi, it is so nice that you wrote these two setting up notebook, it helps a lot, but when I was running the example/setting_up_environment_full，I got these error messages, could you help me out?

env.reset()
take_some_steps(env, 100)
render_all_modes(env)

Hint: Wrong Strategy.get_state() parameters?

@djoffrey , oops my mistake, corrected, update package. As error log says, state shape was defined as:

    state_shape={
        'raw_state': spaces.Box(low=-10, high=10, shape=(30,4)),
        'price_gradients': spaces.Box(low=0, high=1, shape=(30,4))
    },

but should be:

    state_shape={
        'raw_state': spaces.Box(low=-10, high=10, shape=(4,4)),
        'price_gradients': spaces.Box(low=0, high=1, shape=(4,4))
    },

@Kismuz Thanks, I don't got enough understanding of all these staff right now, so your notebook and answer helps me a lot!
