raw_input error and ALSA lib problems

chippey5 opened this issue 10 years ago · comments

Hello there, as a github newbie I encounter some problems on my machine running Manjaro Linux. Any help will be appreciated

I have the requirements installed and when running send.py I get the following messages:

ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe
ALSA lib pcm.c:2239:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side

Welcome to quietnet. Use ctrl-c to exit
Traceback (most recent call last):
File "send.py", line 51, in
message = raw_input("> ")
NameError: name 'raw_input' is not defined

Is anyone else getting this?

What version of python are you using? This was built and tested using the Anaconda bundle.

I am running Python version 3.3.4-1, from the AUR repository.

You need use python 2.7.

I also have Python2 version 2.7.6, but after changin raw_input to just "input", the script worked! Or at least, it now recognizes the string. Instead I get this now:

ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave

Additionally I get this on the listen.py script:

print ''

SyntaxError: invalid syntax

Thanks for helping me out! ^^

I installed this package in hope for it to work, but unfortunately no luck: https://aur.archlinux.org/packages/python34/

Use the second commit too.

The send.py seems to work!

and keeps loading until I abort it:

Edit: listen.py does work, I think my laptop's microphone is bad and just too close to the speaker. Thanks a bunch for your help! Will be fun following this project and learning from it! =)
