安装numba for python

Question

我正在尝试为python安装numba，但在按照主页上的说明进行操作后，我得到了这个错误，即找不到extension_types页面。

如果有人知道我做错了什么，或者如果我错过了一些我应该安装的东西，我将非常感激。

非常提前感谢您。

编辑:我通过以下方式安装numba：

git clone https://github.com/numba/numba.git
cd numba
python setup.py install

当我尝试通过pip安装它时，我得到以下错误：

pip install numba --upgrade

Answer 1

我希望您使用的是Linux，并且安装了pip。在我的Debian Linux上，我可以通过以下命令轻松地安装numba：

sudo apt-get install build-essential
sudo apt-get install llvm
pip install llvmpy
pip install cython
pip install numba

然后你就完成了！

Answer 2

我遇到了同样的问题，对我来说，解决方案是将distribute升级到0.6.45。

Answer 3

在windows上运行时，我添加了安装Miniconda时遇到的相同问题

conda install numba 

这将安装一个python解释器和所有numba的包，然后我将这个包复制到我的解释器的环境中

你的任务完成了
