@loboere Hi, for second error, create a ./res folder then run the command

[loboere]

I already created the folder but it still gives the same error

[wyhsirius]

@loboere I see, you have to create ./res/vox manually. Now it should be ok, I have updated run_demo.py, the folder will be created automatically.
