Install RoboStack against Python 3.10

[USeebi]

Package name

Colab

Operating System(s)

• linux-64
• linux-aarch64
• osx-64
• osx-arm64
• win-64

Additional context (optional)

I would like to run RoboStack on Google colab. I tried to have a Python 3.11 venv as well as to update colab python version but both have obstacles beyond my comprehensions.

I wonder is it possible to install an older version of RoboStack against Python 3.10?

Links and references (optional)

No response

Unfortunately this is not feasible due to maintenance time. In theory it would be easy to do, but each additional Python version doubles the build time (+dealing with compatibility issues for multiple versions). See e.g. RoboStack/ros-humble#97

Furthermore, on colab you would need not just any Python but installed via conda in particular, which as far as I understand is not easy either.

Thanks very much for your prompt reply!

I understand the burdens to maintain a cross-platform packages. How about just the bare minimum say only up and running for turtlesim for proof of concepts to have RoboStack on colab. Conda is not a problem as long as the Python version of colab is kept. https://datascience.stackexchange.com/questions/75948/how-to-setup-and-run-conda-on-google-colab

Anyway is there any procedures to built/install RoboStack from sources could be shared?

Many thanks!

Yes, building locally should be relatively straightforward, see https://robostack.github.io/Contributing.html

Thanks Tobias,

I tried the Python 3.11 version on a local installation with juypterlab and I got ModuleNotFoundError: No module named 'notebook.utils' from the following:

This is the same error I got with colab that is out of my comprehension. What did I miss?

That seems unrelated to RoboStack - my best guess is some version incompatibility with a too new version of “notebook”; there are several reports on this on StackOverflow.
