AttributeError: Wave_read instance has no attribute '__exit__'

[rileycrane]

Hi,

I'm trying to get this working. I've done the hardware mod (is there a way to test if it's successful?). Every time I run main.py I hear "hello" and then when I connect together Pins 14 and 1 on U14 I get the following error:

Traceback (most recent call last):
  File "main.py", line 128, in <module>
    with wave.open('beep.wav', 'rb') as f:
AttributeError: Wave_read instance has no attribute '__exit__'

Any ideas would be appreciated. Also, I had problems installing alsa based on your instructions. I had to install mpg321 independently.

Thanks!

I am experincing the same issue as @rileycrane @nextthingco commentor advised moving to python 3 instead may help, however when attempting to run main.py with python 3 i get an error that alsaaudio module is not found. I installed pip3 to run the install with pip3 which failed out stating that multiple items were not found.

I have been working on getting a cheap BT speaker/headset to act as the audio out/in, but if you haven't already, you might try switching from the jack to pins 10 and 12 on U14: http://docs.getchip.com/#pin-headers (to see if it's related to the cutting / soldering).

[PantherTheCat]

@tobiasboyd I am using 10 12, I also used the mic in/ hpcom as an attempt.
I have run this on 2 different CHIPS now - one that was using the TRRS mod, which i reversed and then seutp the jack through the header pins.
The second, I never did the mod, and used only the pins. (The second, gave me the same error once I ran the main.py and pressed the button/shorted GND - XPIO1)

I tried again using python 3, reinstalling everything Alsa & memcache specific for python 3 installation, while I no longer get the wave error, I get a new error stating

chip@chip:~/echo$ sudo python3 main.py
Traceback (most recent call last):
File "main.py", line 131, in
audio += data
TypeError: Can't convert 'bytes' object to str implicitly

[tobiasboyd]

@PantherTheCat : that error seems less mysterious, audio is implicitly cast to a str in line 126. Do you get the same error if that's audio = None ?

[PantherTheCat]

@tobiasboyd - I will see what happens when I try that modification. I have been working with another user who has made several code modifications that I was also going to attempt.

[PantherTheCat]

@tobiasboyd yes same error.

@jitto created a python 3 version that gets further. Although I still end with an error - Although the error is after the button is released, instead of on press - so that is progress 😸

Figured it out, the TRRS jack mod was not scored deep enough, so it was not recording. Everything working now.

[al-jimenez]

@PantherTheCat I am getting the same error. I am using a USB microphone numb and the TRRS jack for audio output. I would prefer not to modify and score the CHIP board. Is there a way of not getting this error if you DON'T modify the board? Python3, etc installed...

NOTE: I have audio capture working and audio output working with arecord/aplay, just get the same error when I run python main.py:

Traceback (most recent call last):
File "main.py", line 119, in
alexa()
File "main.py", line 99, in alexa
data = r.content.split(boundary.encode('utf-8'))
UnboundLocalError: local variable 'boundary' referenced before assignment

I don't want to modify the board unless I have to.

Thanks

I'm getting the same error with a bluetooth speaker/microphone, are there any progress?

[zampy24]

I was having the same UnboundLocalError, and for me, it didn't seem to be related to the bit rate or other of some of the solutions out there. So, in main.py, I just put it in a Try block to handle the error and prevent it from crashing. Seems to be working so far... (note: having trouble with the indents....try: and except are at the same indent, everything else is the same, but pushed forward one indent)

try:
            data = r.content.split(boundary.encode('utf-8'))
            for d in data:
                    if (len(d) >= 1024):
                            audio = d.split(b'\r\n\r\n')[1]
            with open("response.mp3", 'wb') as f:
                    f.write(audio)
            os.system('mpg321 -q 1sec.mp3 response.mp3')
   except(UnboundLocalError):
            print('had an error')
            pass

This project is now deprecated in favor of the new AlexaPi (https://github.com/alexa-pi/AlexaPi) which has all the features of this project and much more, such as:

• support for a wide range of devices and platforms (Raspberry Pi, CHIP, Orange Pi, desktops, Magic Mirror and others)
• voice activation (great PocketSphinx support and snowboy support soon to be released)
• much more robust installation and configuration
• better security
• Arch Linux support
• awesome documentation
• and much, much more! You get it - it's just awesome.

Please switch over to the new project and if your issue persists there, file an issue in the new repo's issue tracker. Thank you.
