The robotic arm vibrates continuously when executing the example in example

[AGREATAPE]

@stepjam
Hello, thank you for providing such a good benchmark environment. I tried to learn to use rlbench, but when I executed example（any of
them), I found that the robotic arm kept vibrating and did not perform the desired action, as shown below:

I thought maybe PyRep wasn't installed well, but in fact, the PyRep example worked well.
Can someone help me？
