파이썬 librosa 설치 - paisseon librosa seolchi

librosa 설치 오류

Librosa를 처음 설치하다 보면, 아래와 같이 import도 되지 않는 상황이 종종 발생하곤 한다.

아무리, pip 명령어를 만져봐도 시작부터 되지 않는 경우이다. 

sndfile library not found

librosa는 내부적으로, scipy.wavefile과 sounfile 라이브러리를 사용하는데, soundfile 라이브러리 설치가 잘 안되서 발생하는 문제이다. soundfile library는 파이썬 외에 os차원에서 설치해야하는 library가 포함되어 있기 때문에, pip 및 종속성검사로 설치가 되지 않는다. 

Librosa 공식웹페이지 이외, Github Page를 참조하면, Soundfile을 설치할 때 다음과 같은 사전설치/업데이트가 필요하다고 가이드 되어 있다. (놓치기 쉽다. 그냥 `pip install librosa` 하기 때문)

apt-get install ffmpeg   # Linux

또는,

apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly

MacOS의 경우

brew install ffmpeg
   혹은
brew install gstreamer

Conda를 사용하는 경우,

conda install -c conda-forge ffmpeg
conda install -c conda-forge librosa

conda 가 지원하는 환경이라면, conda 최고~~~!!!

그런데, 이렇게 해 주어도 안되는 경우가 있다. 그렇다면 아래와 같이 해 주자. 

soundfile library를 다시 설치 해 주자.

sudo apt-get update
sudo apt-get install -y libsndfile1-dev

간혹 설치 완료 후에도 여전히 에러가 발생하는 경우가 있는 Notebook을 재시작 해주면 해결 된다. ^^;

Install librosa on Windows #

To install the librosa module on Windows:

1. Type CMD in the search bar and open the Command Prompt application.
2. Type pip install librosa and press Enter.

Copied!
pip install librosa

# 👇️ for Python 3
pip3 install librosa

# 👇️ if you don't have pip in your PATH environment variable
python -m pip install librosa

# 👇️ for Python 3
python3 -m pip install librosa

# 👇️ using py alias
py -m pip install librosa

# 👇️ if you get permissions error
pip install librosa --user

# 👇️ for Anaconda
conda install -c conda-forge librosa

If the command doesn't succeed, try running CMD as an administrator.

Right-click on the search result, click on "Run as administrator" and run the pip install command.

If you get the error "ModuleNotFoundError: No module named 'librosa' in Python", check out my other article:

• ModuleNotFoundError: No module named 'librosa' in Python

If you get the error "'pip' is not recognized as an internal or external command", use the python -m command when installing librosa.

Copied!
python -m pip install librosa

python3 -m pip install librosa

py -m pip install librosa

Alternatively, you can install the librosa module in a virtual environment:

1. Open the root directory of your project.
2. Press Shift and right-click in Explorer.

1. Click on "Open PowerShell window here".
2. Run the following commands.

Copied!
# 👇️ might also be: "python3 -m venv venv"
python -m venv venv

# 👇️ activate on Windows (PowerShell)
venv\Scripts\Activate.ps1

# 👇️ activate on Windows (cmd.exe)
venv\Scripts\activate.bat

# 👇️ install librosa in virtual environment
pip install librosa

If the python -m venv venv command doesn't work, try the following 2 commands:

• python3 -m venv venv
• py -m venv venv.

If you see an error message that "ps1 cannot be loaded because running scripts is disabled on this system", run the following command, type "yes" when prompted and rerun the activation command.

You can verify that the librosa module is installed by using the pip show librosa command.

Copied!
pip show librosa
pip3 show librosa

python -m pip show librosa
python3 -m pip show librosa

The pip show librosa command will either state that the package is not installed or show a bunch of information about the package, including the location where the package is installed.
