MPF crashing at startup

[leeoneil]

Hello everybody,

i have a strange issue with MPF.

I was running with 0.55, everything was working.
Today I started having some crash launching a game, but not due to my file.

So I tried to install the 0.56.

I've uninstall everything, repaired python, and nox it's impossible to launch mpf.

With mpf --version it says 0.52.2
Python is 3.9.13

When I launch mpf, i have this message :

Failed to initialise MPF
Traceback (most recent call last):
  File "C:\Program Files\Python39\lib\site-packages\mpf\core\machine.py", line 679, in initialise_mpf

Does somenone already have this kind of problem ?

thank's !

If mpf says it's 0.52.2 it probably isn't running 0.56.

Does it work if you run with -x? I'm no expert but serial_exception sounds like it's problem to access your hardware, just guessing. :/

I would try (for troubleshooting) make a new profile in Windows and install everything again and try. A new profile is like starting fresh. If you run Linux I'm not completely sure how to proceed.

Cheers.

I would uninstall and reinstall MPF. If you do standard install you will get 0.56.2 (I think, subversion could be higher). 0.52 didn’t support python 3.9, which is why it won’t work.

thank's ! So I reinstall totally windows, and begin again the installation for MPF (much easier now thaht I remenber).

But now mpf MC not working... Seems that mpf running (but impossible to test switches). (waiting for media controller)

MPF 0.56.2 not 0.52 sorry !

[Johan Gill]

You really don't have to reinstall Windows. Just create a new profile if you want to start fresh.

Ok thank's it was the brutal way....

So a problem of exception as you said... If I launch mpf mc alone, i have this :

I guess it's this problem...

https://github.com/missionpinball/mpf-mc/issues/436

Have it as well on new installation.

Ok, thank's !
If I follow the links correctly it's supposed to be solved.

So I tried installing the MPF 0.57 but I have no luck with it... 

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
mpf-mc 0.56.1 requires psutil==5.9.4, but you have psutil 5.9.5 which is incompatible.
mpf-mc 0.56.1 requires ruamel.yaml==0.15.42, but you have ruamel-yaml 0.17.32 which is incompatible.

Gosh... impossible to run, even starting from a fresh computer... I'm lost...

[Avery Tummons]

Uninstall MPF. When you type pip list in command prompt you should see a couple things only (no mpf, etc.).

Then reinstall mpf and mc. Then if it still doesn’t work please run pip list in command prompt and post the results.

Trying uninstalling and reinstalling kivy audio dependencies give me this :

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

Can it help ?

[Ernie Silverberg]

Run pip install rumael.yaml==0.17.32 —force and same for psutil

Thank's, I tried for rumael but the installation give this error message :

ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.

mpf-mc 0.56.1 requires ruamel.yaml==0.15.42, but you have ruamel-yaml 0.17.32 which is incompatible.

mpf 0.56.2 requires ruamel.yaml==0.15.42, but you have ruamel-yaml 0.17.32 which is incompatible.
Successfully installed ruamel.yaml-0.17.32

Anyway it's installed, but mpf mc does not launch anymore.

I tried pip install psutil but wich version do I need ?

[leeoneil]

I managed to install 0.57.0.dev21

I installed the ruamel.yaml 0.15.32

and it's still not working.
MPf -x launch, but same error with MPF MC (I installed the last version,, and mpf-monitor on the last version)

Gosh.....

Crazy....

[Anthony van Winkle]

Moving between MPF versions can be particularly fraught without the use of virtual environments, which isolate your entire python setup (including pip and all packages). What you're experiencing now is versions of packages installed by different versions of mpf/mc not always being accepted by other versions.

I once wrote a tutorial on setting up virtual environments for MPF, but that was a few generations ago and with all the refactoring of the platform over the last year, it's no longer there. I'll start rewriting it for the 0.56+ editions, but in the meantime you can google how to setup a python virtual environment and I suggest doing that. When you have a fresh virtual environment, existing packages won't impact because only those in the virtual environment will be used.

All that being said, the audio interface issue was also found on 0.57 and fixed with a workaround for windows. I've created a new pull request to backport this functionality to 0.56: https://github.com/missionpinball/mpf-mc/pull/453

[leeoneil]

SOLVED !!!!!!

So I formated c:/, new install of win 10 64.

I started with python 3.11 and the last version of MPF, MPF MC and MPF Monitor (0.57)

I made the changes in my files, and it's starting again (at least the attrack mode, need to test further for the other mode).

thank's everyone with your help, i was going crazy !
Thank's to all the developmment team of MPF, I hope I can pay you a beer one day, your work is amazing !

Just for information I had the same problem with openGL, problem solved here : (7) Kivy fatal error or openGL not detect problem - YouTube
