RLBench returning incorrectly shaped gripper_matrix and wrist_camera_matrix?

[ericrosenbrown]

I pulled the current version of RLBench from master, and now whenever I tried to get an observation from the environment I get the following error

Traceback (most recent call last):

I went into the scene.py file, and found that tip.get_matrix().shape was returning a [4,4] matrix, not a [3,4] as the one specified in the file. I changed it (And wrist_camera_matrix) to 4,4 instead and now everything appears to work. Is there something I did incorrectly or is this a bug?

Thanks for pointing out. There was a recent update to PyRep. Will fix shortly.
