No module named 'numba'

当出现"No module named 'numba'"的错误时，可能是因为你的环境中没有安装或者没有正确安装numba模块。下面是两种解决方法：

1. 使用conda安装numba模块：

conda install numba

2. 使用pip安装numba模块：

pip install numba

请注意，如果你已经安装了numba模块，但仍然出现该错误，可能是因为你的numba版本过高。在0.50版本之后，numba删除了decorators模块。你可以通过以下命令查看已安装的librosa和numba的版本：

pip list

如果你的numba版本高于0.50，你可以尝试降低numba的版本或者更新librosa以适应新的numba版本。
