这篇文章主要介绍了音频处理 windows10下python三方库librosa安装方法，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下

librosa是处理音频库里的opencv,使用python脚本研究音频，先安装三方库librosa。

如下通过清华镜像源安装librosa；

如上

librosa ---- 0.7.2

numba-----0.50.0

下面使用librosa，报的是numba的错误！

解决办法：

卸载numba后，重新安装降版本的numba，安装numba==0.48.0

pip uninstall numba

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple numba==0.48.0

python -c "import librosa;print(librosa.__version__) "

可以看到成功安装了正确可使用的librosa库！
