Error loading server extension jupyros ImportError: Error importing numpy:

Issue

I'm not sure if it is a bug, my platform is a portable version of Miniconda3 py311 on Win10, I have no problem to launch ros_noetic but ros_humble seems to be a very different species.

The jupyros extension is installed in the base env, the extension loaded as expected in the base as well as in ros_noetic but got errors below in ros_humble.

I tried the fix from https://stackoverflow.com/questions/61663400/dll-load-failed-multiarray-unmath-when-importing-numpy with
set PATH=%PATH%;K:\Miniconda3\py311\Library\bin
but no help!

What did I miss? What is the correct version of numpy or Visual C++ Redistributable should be used?

Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.

We have compiled some common reasons and troubleshooting tips at:

    https://numpy.org/devdocs/user/troubleshooting-importerror.html

Please note and check the following:

  * The Python version is: Python3.11 from "K:\Miniconda3\py311\python.exe"
  * The NumPy version is: "1.26.4"

and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.

Original error was: DLL load failed while importing _multiarray_umath: The specified module could not be found.

Finally I sorted out the problem by comparing PYTHONPATH between ros_noetic and ros_humble. It seems that the jupyros extension loaded some sort of precedent to the numpy=2.0.1 package installed with it while the PYTHONPATH of ros_humble point to numpy=1.26.4 and lead to the DLL load failure.

I installed numpy=2.0.1 in the ros_humble env and it works. Down the road another offending package is PIL/pillow, I applied the same trick but I got other problems with PIL in Jupyter. By pure fluke I managed to get it done by deleting ros_humble's pillow package while copying the PIL library from jupyros to the PYTHONPATH of ros_humble.

I just wonder are these just asynchronous in development between jupyros and ros_desktop or I did miss something? How the precedent arise in the jupyter extension if there is really any such precedent?

I did try to install jupyros in the same ros_humble env but you still got the same PIL/pillow problem to solve. What would be other successful Windows installations of current distribution of RoboStack out there?

Sorry, which kind of PIL/pillow issue you are having? Thanks!

Do you mix conda channels or pip and conda any chance?

I'm referring to the same problem of replacing pillow=10.3.0 in ros_humble with pillow=10.4.0 in jupyros if you install jupyros after ros_humble_desktop. I don't have the setup to reproduce the problems but I can illustrate with the correct ones

This display would be magnified at least 3 - 4 times.

The Start Stop widgets buttons not running due to some javascript problems.

There are some other issues to run the ipynb in notebook.

jupyros was installed by pip install --pre jupyros==0.7.0a0 according to #157 in the base env

ros_humble_desktop are installed strictly by the Getting Started manual.

What would be other valid combinations?
