Failing to create variables in euler1d.py #1

Gene0315 · 2024-06-30T15:23:34Z

Following the issue solvcon#361
The PR sets the plotting points as an array 'pt_plot'. And then, it changes the points shown on the figure from coord[::2] to coord[self.st.svr.pt_plot].

However, there is something wrong in this code. It failed to create the variable 'svr.pt_plot' in 'modmesh/modmesh/onedim/euler1d.py'.

Please paste the complete traceback with the error

Please paste the complete traceback with the error

I ran the python files in VSCODE and got the traceback below.

What is the command you run? If you (cd /Users/genelin/modmesh/modmesh/onedim/; python3 euler1d.py), it's wrong. You need to make modmesh searchable in your path, and modmesh.onedim.euler1d cannot be executed as a script.

Sorry, I think I ran the modmesh.onedim.euler1d directly.

In order to run the project correctly, I added a new file startu.py to execute the viewer. I ran it in VSCODE, and pressed the button 'Euler solver' like the picture below.

However, It failed to run the code and the messages are

Where is your pybind11 wrapper?

It is not necessary to use a file to run code like this. A one-liner python3 -c 'import modmesh.view as v ; v.launch()' would do it.

But I'm not sure which file is appropriate to add this code. Is there anything wrong to add the startup.py in modmesh?

You do not need to add the code in a file. That is a one-liner you type in command line.

It is at /Users/genelin/devenv/flavors/new/usr/lib/python3.11/site-packages/pybind11

That is where you install pybind11, not the wrapper. Wrapper is a class and the associated wrapping code like:

            .def_property_readonly(
                "coord",
                [](wrapped_type & self)

            .def_property_readonly(

@yungyuc sorry, I don't know what is resolving the testing failure mentioned above. Does it mean that I have to execute the code by terminal with command

make cmakeclean
make buildext viewer VERBOSE=1

or how can I do it?
