run trpo_cartpole fail on Mac

[lchenat]

RLLAB works fine on the sentOS server, but it does not work on my MAC. When I ran trpo_cartpole.py in examples it stuck here and made no progress:

python trpo_cartpole.py

/Users/lchenat/anaconda2/lib/python2.7/site-packages/theano/tensor/signal/downsample.py:6: UserWarning: downsample module has been moved to the theano.tensor.signal.pool module.
"downsample module has been moved to the theano.tensor.signal.pool module.")

I press Ctrl + C and it shows:

I already upgraded my RLLAB to the latest version.

Seems like you are still using python 2. Could you try python 3?
