导入librosa给出“没有名为numba.decorators的模块”，如何解决？

Question

我安装了librosa，现在我正试图导入它

import librosa

出于某种原因，这让我犯了这个错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Asish nayak\AppData\Local\Programs\Python\Python38-32\lib\site-packages\librosa\__init__.py", line 12, in <module>

为什么即使在安装了库之后也会出现此错误

Answer 1

您需要使用0.8.0之前的任何numba版本

然而，最近的librosa与任何低于0.48的numba都不兼容

至少，这是我在Windows上使用它时发现的。我的解决方案是使用google colaboratory，因为它在导入librosa时没有给我任何错误

Answer 2

由于存在错误，您必须安装numbra版本0.48，请运行

pip install numba==0.48
