如何在python中使用pyinstaller和sounddevice模块获取有效的EXE文件

Question

Unfortunately pyinstaller has problem with the sounddevice module.

I wrote the code below, but when I make an EXE file using pyinstaller, the EXE file in the dist folder does not work. The making process using pyinstaller finishes successfully but the EXE file does not work.

The code is:

import sounddevice as sd

fs=44100
duration =2 # seconds
print('Start')
myrecording = sd.rec(duration * fs, samplerate=fs,    channels=2,dtype='float64')
sd.wait()
print('play')
sd.play(myrecording, fs)
print('end')

Answer 1

Could the problem be that the program exits straight after you do sd.play() ?

Try replacing that line with sd.play(myrecording, fs, blocking=True)

Also, sounddevice is not a perfect library, so you need to do a bit of extra tweaking to make it work:

In your directory where your EXE is located, add a directory called _sounddevice_data and put this file into that folder (if you are using Python 64-bit) or this one (if you are using Python 32-bit).

Try running the EXE, it should work!

Hope this helps!

Answer 2

The selected answer didn't work but helped.

For me, the working solution is to add _sounddevice_data folder where the .exe file is located then making a portaudio-binaries folder in it and finally putting libportaudio64bit.dll in the recently created folder.

Hope it helps!
