make: *** [install] Error 1

提示zlib未安装

brew install zlib

同时还要设置环境变量

export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
export LDFLAGS="-L/usr/local/opt/zlib/lib"
export CPPFLAGS="-I/usr/local/opt/zlib/include"
export PKG_CONFIG_PATH="/usr/local/opt/zlib/lib/pkgconfig"

再运行pyenv install 3.7.0安装成功

安装Spleeter

pip install spleeter

setuptools版本不对

tensorboard 1.14.0 has requirement setuptools>=41.0.0, but you'll have setuptools 39.0.1 which is incompatible.

pip版本也低

You are using pip version 10.0.1, however version 19.3.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

先升级pip

pip install --upgrade pip

再安装setuptools

pip install setuptools==41.0.0

再重新安装 spleeter

pip install spleeter

安装成功

使用spleeter

spleeter separate -i 1.mp3 -p spleeter:2stems -o out

OSError: FFMPEG binary (ffmpeg) not found

提示ffmpeg未安装

brew install ffmpeg

安装完成后,正常工作

➜  split spleeter separate -i 1.mp3 -p spleeter:2stems -o out
INFO:tensorflow:Downloading model archive https://github.com/deezer/spleeter/releases/download/v1.4.0/2stems.tar.gz

但是速度很慢 ,可以将https://github.com/deezer/spleeter/releases/ 中的几个文件下载

解压后放到 pretrained_models下

可以正常工作了.
