librosa是處理音頻庫里的opencv,使用python腳本研究音頻，先安裝三方庫librosa。

如下通過清華鏡像源安裝librosa；

如上

librosa ---- 0.7.2

numba-----0.50.0

下面使用librosa，報的是numba的錯誤！

解決辦法：

卸載numba后，重新安裝降版本的numba，安裝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__) "

可以看到成功安裝了正確可使用的librosa庫！
