same error, did you solve it?

[Iris-Orion]

same error, wondering whether you've solved it

Hi, here is how i solved it :
. you should open /ROS/Unity-Robotics-Hub/tutorials/pick_and_place/ROS/src/ros_tcp_endpoint/src/ros_tcp_endpoint/default_server_endpoint.py
. i open this .py in vim and change the first line #!/usr/bin/env python to #!/usr/bin/env python3
this works for me and i think the main reason is you should use python3 in ros noetic instead of python

I have the same problem as you. Have you solved it?

I fix it.
Open default_server_endpoint.py change first line
" #!/usr/bin/env python" To "#!/usr/bin/env python3"

If the problem persists after changing the first line of the script to #!/usr/bin/env python3 check the file format.
For me it was the case that I copied the example code into my Ubuntu VM from a Windows machine where I cloned the repository. So it couldn't read the path properly and looked for /usr/bin/env: ‘python\r’: No such file or directory. If that's the case for you as well and your ros environment runs on a unix based system change the file format to unix

sudo apt install dos2unix
dos2unix default_server_endpoint.py
