我在Ubuntu 14.04,我的numba 0.15工作正常。
我跑了:
pip install --user --upgrade numba
升级到numba 0.16但现在当我尝试导入numba时出现以下错误:
~/.local/lib/python2.7/site-packages/numba/__init__.py in <module>()
4 from __future__ import print_function, division, absolute_import
5 import re

----> 5 import llvmlite.llvmpy.core as lc
6 import llvmlite.llvmpy.ee as le
7 import llvmlite.binding as ll
ImportError: No module named llvmlite.llvmpy.core
这很奇怪,特别是因为我发现了这个:
问:我是否需要删除或更新llvmpy?
<答:答:不,Numba根本不再使用llvmpy。

任何想法?
答案 0 :(得分:1)
可以找到答案here:
Numba 0.16已经从使用llvmpy变为llvmlite作为LLVM库的包装器。 (我们也同时从LLVM 3.3升级到LLVM 3.5。)
此处描述了安装过程:

(另请注意,llvmlite(很像LLVM 3.5)需要构建C ++ 11编译器,这在较旧的发行版中很难实现。)
该行是:

我的解决方案:
pip install numba==0.43.0
pip install llvmlite==0.32.1
