[michaelchi08]

Hello,

I'm trying to run these examples on my ubuntu 18.x VM.
I managed to install pybullet and numpy.But when i run the test, i get this

Traceback (most recent call last):
File "", line 1, in
ImportError: No module named ss

Thanks for your help.
When i try to run to run the kuka test, i also get some errors

Hi Michael,

Run the following commands to update a submodule that ss-pybullet depends on. I've updated the installation instructions to include these directions.

$ cd ss-pybullet
$ git submodule update --init --recursive

Hello Caelan, I'm able to run the example now but getting this. I ran the PR2 example and it ran fine. Do you know what might be going on?

I fixed an issue with the kuka's URDF path. It should work again now.

Hmm, what's in master is currently working for me. Can you check that that following URDF paths are correct?
