[feature request] Run jupyter-ros on google colab about jupyter-ros HOT 12 OPEN

It seems like the ipywidgets are not installed / activated.

Running this

jupyter nbextension enable --py --sys-prefix widgetsnbextension

would hopefully do the trick.

from jupyter-ros.

works for me, but also had to run sudo apt install python-rosgraph.

Thanks, I will try.
Can you add a screenshot with the messages received?

from jupyter-ros.

I also get this.
I solved the graph problem, by add /opt/melodic/bin to PATH. but your solution is more elegant.
but i don't see the msgs.
Did you see them?

from jupyter-ros.

I update the file,
I run roscore in the background.
I run hello world ros python node in the back ground of string.
I can see the topic with rostopic list, and see the data in rostopic echo,
but I cannot see the msg inside the jr.subscribe only big button of stop.
Any suggestions?

Thanks for your help! :)

I have the same issue as @talregev:
publishing with jupyros is possible but I cannot see the messages in jr.subscribe.
The same is for visual data like the output of ros3d.viewer. I was trying your TEB example, but after executing the cell, no visualization is seen?
Do you have some ideas how to solve the problem?

from jupyter-ros.

How is your library connected to ros?
Like web-socket?
I don't know how to fix this problem.
But if you succeeded, you will have powerful tool to show the people how your library is work without install any environment on their computer.

I think you should demand google colab to support the real jupyter widgets protocol: googlecolab/colabtools#60

from jupyter-ros.

I read the issue on google colab.
I think google add manually separately each widget.
Can you make a list here all the widgets the lib is using and I will add the request in the relevant issues?

Thanks for your help.

Hi, has this advanced somehow?

I totally agree with @talregev, being able to run ros on colab would be extremely helpful, specially on this time of online learning.

Hi everyone.

Any progress on this issue? I copied the notebook from @talregev but it didn't work, ros wasn't able to run.

I agree with @douglasmacharet, run ros on colab would be an extremely contribution...
