Core dumped when trying to load file
jvadair opened this issue · 7 comments
To reproduce:
from just_playback import Playback
playback = Playback()
playback.load_file('sample.mp3')
playback.play()
This is taken directly from the example!

Hi @jvadair,
Try installing with pip install --no-binary just_playback just_playback
There seems to be a problem with the manylinux wheels probably due to some optimization flags use to build the C extension.
I'm currently investigating this. Any suggestions would be very welcome.
That solution indeed works. Thanks for your help.
I just installed Linux Mint 21 (Kernel 5.15.0-48-generic, Python 3.10.6) and found the following error when trying to use the suggested "no-binary" workaround:
$ pip install --no-binary just_playback just_playback

Hi @Obliman,
Does pip3 install --upgrade cffi==1.5.0 fix the problem?
Hi @Obliman,
Does
pip3 install --upgrade cffi==1.5.0fix the problem?
Thanks for the response.
After trying that I received an error due to "libffi" not being found.
I attempted to install libffi using sudo apt-get install -y libffi-dev, then ran the cffi install again, but this leads to a pile of warnings and some errors. I guess this is a cffi issue, or related to the compiler, so I'll do some digging.

ERROR: Failed building wheel for cffi

Failed to build cffi
Okay, per the cffi forum this is related to how Ubuntu handles Python packaging and the current workarounds are to either use a virtualenv or supposedly find a version of pynacl to install that works.
I found that pip install PyNaCl allowed me to install cffi 1.15.0, but I still encountered the original version mismatch error.
The solution:
Setting up a virtual environment using conda worked with the --no-binary method.
I just want to point out that I encountered this same problem and the issue was the use of AVX-512 instructions. pretty much all AMD cpus (excluding some that came out this year) do not support this instruction set. if you're building the c component with gcc, -mno-avx512f should fix this.
