上網谷歌，找到

《 running librosa & numba on raspberry pi 3 》文本。

依言安裝︰

sudo pip install llvmlite==0.15.0

sudo pip install numba==0.30.1

查核 pip list ，發現此時

llvmlite (0.15.0)

numba (0.36.1)

resampy (0.2.0)

 

或墜『相容性』地獄乎？？

Building llvmlite requires LLVM 3.9.x #234

seibert commented on Feb 21

Unfortunately, because LLVM makes backward incompatible changes with each minor release, llvmlite only supports one version of LLVM at a time. llvmlite 0.15.0 (and Numba 0.30.1) should work with LLVM 3.8, or you will have to install LLVM 3.9 from source.

 

嘗試先裝好

sudo pip install resampy==0.1.5

/resampy

但又為何派生三 OK 呦☆
