Spyder Modelx Plug-in Not found

[jjaredrides]

Description of your problem

Basically: spyder is unable to find the modelx plug-in.

I updated my python interpreter from anaconda to pyenv and am using virtual environments.

I downloaded spyder (e.g, not from the anaconda prompt) and I updated my interpreter and Path to reference my specific virtual environment where modelx and spyder-modelx was downloaded to.

The Ipython console is able to find the modelx library (e.g. no error comes up when I type "import modelx as mx")

For the PythonPath - I added a userpath that references my specific virtual environment where the modelx and spyder-modelx libraries are located.

What steps will reproduce the problem?

1. Go to User Module Reloader (UMR) and set UMR excluded to "modelx"
2. It says: 'the following modules are not installed on your machine: modelx
3. Modelx plug-ins are not found in the "Panes" section either

What is the expected output? What do you see instead?

Please provide any additional information below

Versions and main components

• modelx Version: 0.21.0
• Spyder Version: 5.4.2 (it says the default python that come with spyder says 3.8.10 even though the interpreter is 3.10.9)
• Python Version: 3.10.9
• Operating system: windows 10

@jjaredrides On "Console 1/A" in Spyder, can you see if modelx and spyder-modelx are installed by:

>>> import modelx

>>> import spyder_modelx

[jjaredrides]

Here's what happens. I think I probably need to install Spyder through PIP - via the virtual environment according to the instructions. https://docs.spyder-ide.org/current/installation.html

import modelx

import spyder_modelx
No QCoreApplication instance found. Application patches not applied. You have to call load_stylesheet function after instantiation of QApplication to take effect.

OK then both are installed. Can you also check if spymx-kernels is also installed?

[jjaredrides]

Yes, I see a folder for spymx_kernels.

I think spyder-modelx is not installed in the environment where Spyder is running. Did you install Spyder from the installer available from Spyder's site?

[jjaredrides]

I installed it from Spyder's website (e.g. downloaded it) vs I think I should use PIP to install it to my virtual environment.

[fumitoh]

The manual says that the Spyder installed from the installer doen't support third-party plugins.

[jjaredrides]

So what do you recommend? Should I create a new environment for Spyder modex and install Spyder in that folder? Or switch back to using Anaconda?

[fumitoh]

Anaconda or WinPython works.

Thank you! The problem is now solved. I really appreciate your help and I find your modelx library absolutely fantastic!
