data structure of action in World.step()

[Matt Chapman]

I just noticed that if I print 'action' from in my World.step(), the first time, it is a simple array, i.e.

[0.  0.]

But there after (i.e., once planner has actually selected an action) it is a nested array, i.e.,

[[0.]

 [0.]]

Is this expected? Or indicative of a bug in my World code? Or a bug in BECCA?

 
All the Best,

It's a bug. Thanks for catching it. The latest commit on the github brohrer/becca repo has the fix. 

For a manual fix, change this line in tester.py:

actions = np.zeros(world.num_actions)

to this:

actions = np.zeros((world.num_actions,1))

Cheers :)
