Start VREP simulator

I use these two lines of code in the Jupyter notebook

from poppy.creatures import PoppyErgoJr jr = PoppyErgoJr(simulated='vrep')

But always such an error：
SerialException: could not open port ‘/dev/ttyAMA0’: FileNotFoundError(2, ‘系统找不到指定的路径。’, None, 3)

what reason？

You should write simulator='vrep'.
