找不到numpy.\u在测试pysparse时导入\u工具

installing pysparse 对于Python版本2.7.15:

$ pyenv local 2.7.15
$ pip install pysparse==1.2-dev213

我试图测试安装,如图所示 派斯派尔 home page testSuperlu.py ,我得到以下错误:

Traceback (most recent call last):
  File "testSuperlu.py", line 3, in <module>
    from pysparse.tools import poisson
  File "/home/hakon/.pyenv/versions/2.7.15/lib/python2.7/site-packages/pysparse/__init__.py", line 6, in <module>
    from numpy._import_tools import PackageLoader
ImportError: No module named _import_tools

numpy._import_tools 他失踪了。我正在使用 numpy

:

pyparse 和 :

$ pip install pysparse==1.1.1-dev
$ pip install numpy==1.15.1

然后运行测试程序 testSuperlu.py 再一次:

$ python testSuperlu.py
ImportError: No module named _multiarray_umath
Traceback (most recent call last):
  File "testSuperlu.py", line 3, in <module>
    from pysparse.tools import poisson
