Cecilia – how to make it work again?

Post by thebutant »

I'm such a fan of Cecilia!
Yet, I've been unable to run it for the last 9 months.
Since upgrading from Pop! _OS 21.10 to Pop! _OS 22.04, it won't launch.
And now, as I've been without it for so long, I'm really starting to miss it.
I wish I could make it work.

On Pop!_OS' reddit this topic has been discussed a little, but so few people feel the need for Cecilia, so nothing came out of it.
My hope is that someone here has a solution.

When trying to launch Ceclia, this is what happens:

Is it obvious to anyone what the problem is here?
And even better: How to solve it?

Re: Cecilia – how to make it work again?

Post by slangbein »

just a guess. I downloaded Cecilia 5.4.1

in your log file cecilia uses for its GUI a package called WxPython. There it fails. It could be a version mismatch.

Here what they say about required packages and their versions:

  • Python 3.6 <https://www.python.org/downloads/release/python-368/>_ or
    Python 3.7 <https://www.python.org/downloads/release/python-379/>_ (preferred) or
    Python 3.8 <https://www.python.org/downloads/release/python-385/>_.
    The programming language used to code the application.

  • WxPython 4.1.0 (Phoenix) <https://wxpython.org/pages/downloads/>_
    The toolkit used to create the graphical interface. (install with pip install wxPython)

  • pyo 1.0.3 <http://ajaxsoundstudio.com/software/pyo/>_
    The audio engine which gives his power to Cecilia. (install with pip install pyo)

  • numpy <https://pypi.python.org/pypi/numpy>_
    Array processing module for numbers. Used to accelerate the grapher display.
    Install the last stable version.

Thanks, that's a good answer!
I discovered that Pop!'s version of wxPython is 4.0.7, while Cecilia requires 4.1.0.
So I'll look more into that part.
The strange thing is that Cecilia has worked in every earlier Pop!_OS version I've had over the years.

By the way, slangbein sounds like the most Norwegian nick I've heard. :wink:
Coincidence?

Haha.
Now you know how well you'd fit in in Norway. :D

Perhaps with previous versions you performed the documented incantation to install WxPython?

Code: Select all

$ pip install wxPython

But now, your PopOS! is shipping a version of it, which is not making obvious that you need to install an up-to-date version?

Ubuntu, Mixbus32C; acoustic blues / country / jazz
