german model with docker-kaldi about docker-kaldi-gstreamer-server

[jcsilva]

Some questions that should help solving this problem:

1. Your master is up?
2. Is there any worker connected to this master? How many?

When you receive the message "no decoder available", the server is telling that there's no free worker connected to the master at that moment. You should check why this is happening (maybe someone else is using your server)

Hi!
Today I ran into the same issue. The worker does not come up with this model.

It seems that it cannot open all the files that are referenced in the yaml file.
Files are there in the mentioned subfolder.

Any idea?

[nanosonde]

Got it working. It seems to be an issue with the paths.
I have edited the yaml file and replace all paths with absolute paths starting with /opt/models/

After that I have restarted everything and the worker comes up. I have just down my first german STT using this. Great!

[nanosonde]

It is working, but I had to struggle with this issue here:
alumae/kaldi-gstreamer-server#168

So commenting the post-processing line in a yaml file seems to sove this issue.
