Error in training

[RemaDaher]

Hello,
When I run the following command:

python -m baselines.run --alg=ppo2 --env=RobotExploration-v0 --network=cnn --num_timesteps=2e7

I get the following error:

ValueError: operands could not be broadcast together with shapes (11,10) (11,11)

I solved this in pseudoSlam.py by replacing:
worldPatch= worldPatch * robotPatch
with:
rowWorld,colWorld=np.shape(self.world)
if (py-r)>=0 and (px-r)>=0 and (py+r+1)<=rowWorld and (px+r+1)<=colWorld:
worldPatch= worldPatch * robotPatch
