在並行Python中導入NumPy

大家好，我是PP的新手，但是在用PP導入NumPy時遇到問題。在並行Python中導入NumPy

基本上我試圖做的是提交一個函數到ppserver，這取決於NumPy。我已經在代碼的一開始就使用（import NumPy as nu）導入它，但是當我運行代碼時，它給了我找不到共享對象multiarray.so的錯誤。

的情況完全同樣在這裏：parallel python forum

如下代碼附加：（我正在運行的Python 2.7.2 + PP 1.6.0 + numpy的1.5.1）

import numpy as nu 
import pylab as pl 
import pp 
job_server = pp.Server(secret="123456") 
print "Starting pp with", job_server.get_ncpus(), "workers" 

aa = GrRib() 
job = job_server.submit(aa.plotwavefunc, (band,k),(nu,pl,signal)) 
result = job()

錯誤看起來像：

An error has occured during the function import 
Traceback (most recent call last): 
    File "/usr/lib/pymodules/python2.7/ppworker.py", line 86, in run 
    exec __fobj 
    File "<string>", line 127, in <module>

    File "/usr/share/pyshared/numpy/core/__init__.py", line 5, in <module> 
    import multiarray 
ImportError: No module named multiarray

任何人都可以幫我嗎？我理解它，因爲我將不得不更改目錄PP正在尋找pyshared對象。

我可能是錯的，但我相信你提交這份工作的方式是錯誤的。如文檔（http://www.parallelpython.com/content/view/15/30/#QUICKSMP）所示，第三個參數（不包括「self」）是依賴函數。而且，模塊必須是字符串。我假設「band」和「k」是依賴函數，因爲我沒有看到他們的聲明：

job = job_server.submit(aa.plotwavefunc, depfuncs = (band,k), modules = ("numpy","pylab","signal"))
