python - 导入错误: cannot import name pynestkernel

Question

所以我昨晚尝试安装 Nest(和 pynest)以与 PyNN 一起使用，但目前我陷入了困境。当我尝试导入 Nest 时，我得到:

>>> import nest
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/nest/__init__.py", line 52, in <module>
    from . import pynestkernel as _kernel
ImportError: cannot import name pynestkernel

但是，当我进行 make installcheck 时，它通过了所有 pynest 测试。 我使用的是 OS x Yosemite，并且使用 macport 重新安装了 python 2.7.9。

尝试过:

easy_install python-nest

现在我收到一个新错误。

获取:

>>> import pyNN.nest as sim

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import pyNN.nest as sim
  File "/Library/Python/2.7/site-packages/pyNN/nest/__init__.py", line 13, in <module>
from pyNN.nest import simulator
  File "/Library/Python/2.7/site-packages/pyNN/nest/simulator.py", line 500, in <module>
state = _State()  # a Singleton, so only a single instance ever exists
  File "/Library/Python/2.7/site-packages/pyNN/nest/simulator.py", line 60, in __init__
self._cache_num_processes = nest.GetKernelStatus()['num_processes'] # avoids blocking if only some nodes call num_processes
AttributeError: 'module' object has no attribute 'GetKernelStatus'

Answer 1

尝试使用setuptools通过easy_install python-nest安装nest。
