Problems with installing a new Wake word with Wake word Trainer

JulianFV · May 15, 2021, 12:54pm

Hey all,
I tried to change the Wake Word to “Edith” with the Wake Word Trainer, unfortunately an error occured and I don’t know how to handle that (even though I searched the internet for it). Maybe you have a clue? I post my output afterwards.
Thank you very much and kind regards,
JulianFV

Seems pretty straightforward?

JulianFV · May 16, 2021, 9:22am

Hey Baconator,
thank you for your fast reply!
Even though there may be the error because that file can’t get opened, there is the problem, that this file did not had to be created in the first place. As far as I understand it, the Wake word trainer should run the whole implementation of a new wake word so if that file is not there, what should I do?
Thank you for your answers in advance,
best,
JulianFV

It’s probably a permissions issue that it can’t create that file.

JulianFV · May 29, 2021, 1:54pm

Okay, but shouldn’t the wake word trainer be able to create that file when it is its purpose to install a new wake word? What should I do to get that new wake word done?
Thanks!

Yes. That’s the problem, it’s having trouble either creating it or reading it. As to why, that’s an issue you need to do some work on–did you install as root and now running as another user? Drive issues? Gamma rays? Electron shortages?
