script main_0210_all_joints.py cannot run

[YechenZhou]

I am grateful to you for providing the CPG algorithm code of the snake robot based on the Matsuoka oscillator. When I download these file, open the scene file and run main_0210_all_joints.py, the error "NameError: name 'clientID' is not defined" is reported. Then I try to add a line "clientID = vrep.simxStart('127.0.0.1', 19997, True, True, 2000, 5)", then select "mode 2" and error "NameError: name 'VREP_com' is not defined" is reported. Could you give me some suggestions to run your project? Thx.
