如何安装 Numba

Question

我在安装 Numba 时遇到问题。

from numba import jit, cuda

我有 anaconda，我安装了 Numba 正在做

conda install numba

我收到以下错误

[Running] python -u "c:\Users\Eric\Desktop\github_projects\snapchat_download_and_rename\download_and_rename_41.py"
Traceback (most recent call last):
  File "c:\Users\Eric\Desktop\github_projects\snapchat_download_and_rename\download_and_rename_41.py", line 30, in <module>
    from numba import jit, cuda
ModuleNotFoundError: No module named 'numba'

现在如果我这样做了

pip install numba

我收到此错误

    PS C:\Users\Eric> pip install numba

  note: This error originates from a subprocess, and is likely not a problem with pip.

[notice] A new release of pip available: 22.3.1 -> 23.1.1

PS C:\Users\Eric> 

之后我尝试了

pip install numba==0.57.0rc1

它安装得很好，但是当我尝试运行该程序时，我收到此错误

During handling of the above exception, another exception occurred:
