4Mic-Array - DoA not working

Hi there,

I installed the 4Mic-Array by following your instructions on <LINK_TEXT text=“http://wiki.seeedstudio.com/ReSpeaker_4 … pberry_Pi/”>http://wiki.seeedstudio.com/ReSpeaker_4_Mic_Array_for_Raspberry_Pi/</LINK_TEXT>

I want to install DoA without a keyword, so I skipped that step and went on with “DoA without Keywords”. After I installed “mic_array.git” and wanna run “python vad_doa.py” it says “ImportError: No module named webrtcvad”. It took me some time to find out that I have to install “sudo pip install webrtcvad” which you you never mentioned anywhere, so I had to figure it out by myself --> please change that!!

Now I tried to run “python vad_doa.py” again and now it says “ImportError: No module named usb.core”! I can’t find it and “sudo pip install usb.core” is also not working.



So I have 2 questions:

1.) how to get “usb.core”?

2.) why are your instructions missing so many information?? (one problem is following the other, in almost every step! nothing works at first try!)



Thanks in advance,

Chris

I am very disappointed that seed studio doesn’t give a shi* about their customers and don’t even bother to give any reply at all !!!

Not only to my request, but almost all requests in the past weeks/months!



Shame on you seed studio!

Dear Chris,

I am super sorry for all the disappointments and inconveniences brought to you. I am deeply sorry and ashamed that you had such a bad experience with us because of the slack communication from our side. We’d like to extend our sincere apologies!

We’ve expected the forum to be an interface for us to communicate with you, with our customers and the whole community, a place that you feel comfortable to communicate and get support and services whenever you need it. However, we did not manage to do it well, no matter in the efficiency or the contents of the replies. There are no excuses for the mistakes and we will need to learn from this and improve our services!

I really appreciate it when you come to talk to us. And I am sorry that the past interactions did not bring you good impressions. We will try our best to make it better and provide better services to our customers and community from all channels no matter on the forum or via emails. I know the current answer is not a satisfactory one, but I hope it conveys our sincerity to you. Sorry again. <3

Hope to be able to see you come back when you feel comfortable to give it another try.



Enjoy a happy day!



Sincerely Yours,

Violet Su

After that, I followed your instructions as you described it, with the following results: [code] sudo pip install webrtcvad [/code] [i]sudo: pip: [b]command not found[/b][/i] (I double-checked the input; it was correct, but the result was the same) [code] sudo apt-get install portaudio19-dev [/code] [i]portaudio19-dev was [b]installed[/b][/i] [code] sudo apt-get install python-numpy [/code] [i]python-numpy was [b]installed[/b][/i] [code] sudo pip install pyaudio [/code] [i]sudo: pip: [b]command not found[/b][/i] (I double-checked the input; it was correct, but the result was the same) [code] sudo pip install pyusb [/code] [i]sudo: pip: [b]command not found[/b][/i] (I double-checked the input; it was correct, but the result was the same)
