Failed installing pyaudio on Google Colab with “ERROR: Failed building wheel for pyaudio”

问题

Trying to install pyaudio on Google Colab but got an error "ERROR: Failed building wheel for pyaudio".

!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg libav-tools
!pip install pyaudio

I got this error:

回答1:

I just need to remove libav-tools from apt install and run this command again.

!apt install libasound2-dev portaudio19-dev libportaudio2 libportaudiocpp0 ffmpeg

Now pyaudio is installed successfully.
