ImportError: cannot import name smart_grasper

Course Support Python Basics For Robotics

Got the following error when trying to run demo 1.2:
Failed to import pyassimp, see https://github.com/ros-planning/moveit/issues/86 for more info
Traceback (most recent call last):
File “arm_control.py”, line 1, in
from smart_grasping_sandbox.smart_grasper import smart_grasper
ImportError: cannot import name smart_grasper

How do I fix this? Or better yet, how can you guys fix this?

Hi @JanPederNilsen,

Thanks for contacting us and welcome to the Community!

You can ignore the pyassimp error, but the other error should not be there. I just confirmed this by following the instructions of Demo 1.2 - my python code ran well.

Could you please check the following:

  • Did you copy the code completely as given?
  • Did you create the python file on your local PC or on the Academy?

Could you please go over the instructions again and check that nothing is missed? Please let us know.

Ok, I’m confused. Does this site have tech support? Now nothing is loading. There must be some sort of tech support that can help? I did just fork out 40 euros for this…

Hi @JanPederNilsen,

I’m sorry about the problems you are facing :frowning:

Could you please elaborate on what you mean by “nothing is loading” - can you share a screen shot?

Things that could apply to “not loading” but are loading fine from here:

  • The home page and other pages.
  • The simulation page (The notebook, IDE, Shells and the Simulation window)

If you are having loading problems, could you confirm:

  • Your internet connection is at least 1mbps DL/UP.
  • You are not behind a proxy, VPN or firewall.
  • ws and wss connections are not being blocked on the network (if applicable).

Looking forward to hearing from you.

Update:
Okay, I have seen your email with the image below. Let me look into it right away. I’m going to terminate your current VM.
Please try again now.

Hello, thank you for your help.
I did get it to work myself by manually checking “activate dns over https” in the network options for firefox.
