VrepIOErrors: Remote error

[Marwanon]

I am trying to connect to the V-rep, the creature is launched on vrep scene and it is opened but I got this error to prevent further the simulation I have tried all the solution discussed here regarding to this matter. I have tried other vrep version (e.g. V3_6_2 and less), it has the same issue
from reachy import Reachy reachy = Reachy(simulator='vrep')

Ubuntu 16.04
Vrep = CoppeliaSim_Edu_V4_0_0_Ubuntu16_04
Pypot = version = '3.1.3'
Poppy.creature = version = '2.0.0'

I would appreciate your help!

VrepIOErrors: Remote error

[cjlux]

From my experience, CopeliaSim (previously V-REP) works rather fine under Linux, and I manage to start sucessfully Poppy-torso, Poppy-Ergo-Jr... in the simulator. The error "VrepIOErrors: Remote error" occurs mostly under windows (from my experience...).

Which robot are you trying to simulate : Poppy-Torso, Reachy, Chapper... ? it is not clear, because the message error you posted begins with chapper = Chapper(simulator='vrep', host='127.0.0.1') => can you clarify this point ?

Thanks cjlux for reply

I am trying to control the Chapper

even before I try to load scene but the Vrep scene became black screen , due to the difference versions of Vrep. lately I tried to update the Chapper using the latest version by downloading CopeliaSim on windows because CopeliaSim on windows can open the Chapper scene, then try to save it as CopeliaSim.ttt to be update on Linux.

After that, I try to import the Chapper, the scene is loaded but after pass the max_time raised that VrepIOErrors: Remote error

I have try to reinstall all the packages with Peachy robot, but it is the same error raised.
Vrep = CoppeliaSim_Edu_V4_0_0_Ubuntu16_04
vrep= 6.0
vrep= 5
All of them raise the same error

May you help me How to fix that,
May you guide me to install the package again and what Vrep.Version using

I would appreciate your help

OK, I'm sorry but I have no experience with the robot Chaper...
But concerning V-REP I successfully used V-REP on windows with Poppy robots using the version 3.3.0 found here : https://v-rep-pro-edu.software.informer.com/download/.
Maybe yoy could try this version to see if ti solves your problem ....
