Archlinuw here I have managed to get mpg and mpf-mc run on python 3.9 and Kivy 2.

Python 3.9 came préinstallés.

Installed Kivy manually to the latest version and tested it before installing mpg.

The I cloned both mod and mpf-mc from GitHub.

In mpf (core/machine.py) I added 9 to the array of minor versions in the version check

And in mpf-mc(setup.py) I removed the ==1.11 from the dependency requirements

Finally I installed the two packages with pip (pip3 install -e . In each repository folder).

Since I am on Archlinuw I had to install all other dependencies manually (gstereamer, ffmpeg etc...) but that's another story.

Nice fact, I achieved ~10sec boot (and still have room for improvement)

MPF dev/0.55 works on python 3.8/9 and uses kivy 2.0. MPF 0.54 still needs older python versions as described in the installer due to kivy 1.11.

I tried installing the dev build instead and it still tried to install Kivy 1.11.1... although as I installed Kivy 2.0 manually before the MPF install, it seemed to install MPF properly. Now when I attempt to run the demo_man example machine to test the install, I get the following error:

How did you install dev? Can you post the log? Can you post "pip3 list"? I guess that either install of dev failed or you did not install dev.

I installed the dev version by downloading the 'dev' zip from git. Then unzipped and ran the install command as directed in the tutorial docs

For some reason you got MPF 0.51 which is quite old. Which install docs did you follow?

https://docs.missionpinball.org/en/latest/install/linux/index.html

Once I got to the "Install MPF using our Installer" portion, I used the link to the GitHub to get to https://github.com/missionpinball/mpf-debian-installer/tree/dev, then selected "dev" in the dropdown instead of 0.54.x. Then I downloaded the .zip with the green button, extracted it, and ran the install command as given in the mpf doc:

chmod +x install && sudo ./install

That sounds good. For some reason you got a really old version.

Should I try redownloading it? Is there a way to check the version from the downloaded folder? Is it possible the wrong version is in GIT?

The installer installs the last non-dev version of MPF. It does not install dev at the moment. You can look the the install scripts. It just runs a few commands and you can run them manually. To install mpf dev just add "--pre" to the pip command.

That seems to have solved that problem, thanks. I can seem to run MPF, but when I try to run in the smart virtual platform, I don't get the expected output in the terminal, there's nothing there. In fact, if I run a simple/empty game as directed in the tutorial, nothing appears: Screenshot from 2021-07-21 16-23-15.png

Checking the log, it looks like MPF is running, but it never seems to initialize the menu in the terminal...

If I run demo_man, the dot pixel display appears, but nothing happens in the terminal window.

Any ideas what the problem is?

Hey John-

Be careful with the -b suffix, that skips the MC connection so you won't get any display updates with that. I'll also note that -X with an uppercase X is for the smart virtual platform, while -x with lowercase x is for the standard virtual platform. I honestly don't know the difference, but I always use the lowercase x.

Other flags that are useful is -t for terminal output, which shows logs instead of the standard UI, and -vV for verbose logging (the lowercase is for file logging and the uppercase is for console logging, wise to use both).

When you run mpf with the both argument, it's a 50/50 chance whether you'll see MPF logs or MC logs in the console. For debugging I recommend running mpf in one window and mpf mc in the other, so you can separate the issues.

So I'd start with mpf -xtvV and mpf mc -vV and see what it says!

Using your commands works and shows me logs instead of the UI. I was using -b to skip the connection because I was testing an empty config file to test MPF as directed by the tutorial. Any idea why the "normal" UI isn't working for me? Neither of the virtual platforms work.

That is a change in dev which is not documented yet and not in the installer yet. Try:

pip3 install --pre --upgrade mpf[all]

To also install optional dependencies. We changed this and made a number of dependencies optional.
