c# – IronPython在线程中使用numpy时抛出InsufficientMemoryExc

我有一些从C#应用程序中调用的Iron Python代码.
这段代码工作正常,直到我决定更改一个函数来运行在一个线程中.
当在python线程中调用numpy函数时,抛出一个InsufficientMemoryException异常.
我搜索了解决方案,但没有找到.有人可以解释为什么会发生这种情况吗？

我认为只有当我有两个使用numpy的线程时,才发生这种情况

我运行这样的代码：

C#：

_python.functionA(); # _python was created with "Python.CreateEngine()"
_python.functionA(); # twice on purpose

Python：
my_python_script.py

import threading
import time
import numpy

def blah():    
    print numpy.array([100,100,0])

def functionA():
    t = threading.Timer(0,blah)    
    t.start()
    time.sleep(2)

我得到这个例外：

Exception in thread Thread-1:
Traceback (most recent call last):
  File "c:Program FilesIronPython 2.7.1Libthreading.py",line 552,in _Thread__bootstrap_inner
    self.run()
  File "c:Program FilesIronPython 2.7.1Libthreading.py",line 756,in run
    self.function(*self.args,**self.kwargs)
  File "C:workspacemy_python_script.py",line 113,in blah
    print numpy.array([100,0])
MemoryError: Exception of type 'System.InsufficientMemoryException' was thrown.

谢谢

我得到这个例外,即使我只运行一个线程,并通过IronPython解释器,没有C#：
