【问题描述】：

我正在运行以下代码（这是开始的sn-p）：

# Import necessary modules and functions
########################################
# time module, for timing it.
from time import time
global starttime
starttime = time()
# psutil for indentifying processor and memory usage
#import psutil
# csv module for loading csv files
import csv
# numpy, a standard module for working with arrays
import numpy as np
# for randomly shuffling arrays
from random import shuffle
# for computing mean squared errors
from sklearn import metrics
# importing modules that contain models we will use
from sklearn import linear_model, ensemble, gaussian_process
from sklearn import neural_network, svm
# importing memory profiler to enable us to determine peak memory usage
from memory_profiler import profile

# Helpful functions
###################

#psutilpercent = psutil.virtual_memory()
#print "\n", " --> Memory Check 1 Percent:", str(psutilpercent.percent) + "%\n"

# This function is for simplifying reading CSV files
def readCSV(path):
    """
    Read a CSV file of floats, with no headder 
    """
    data = []
    mycsv = csv.reader(open(path), delimiter="|")
    for counter, row in enumerate(mycsv):
        if counter != 0:
            data.append(row)
    return np.asarray(data, dtype=np.float32)

但是我收到了回溯：

Traceback (most recent call last):
  File "C:\Users\regression_v6.py", line 38, in <module>
    from sklearn import metrics
  File "C:\Python27\lib\site-packages\sklearn\__init__.py", line 32, in <module>
    from .base import clone
  File "C:\Python27\lib\site-packages\sklearn\base.py", line 10, in <module>
    from scipy import sparse
ImportError: No module named scipy

但我的电脑显示 Scipy 已安装，这是控制面板\所有控制面板项\程序和功能的视图：

有什么想法吗？

【问题讨论】：

PYTHONPATH?你能在 Python shell 中 import scipy 吗？

【参考方案1】：

您是否安装了特殊版本的 scipy？如您的屏幕截图所示'scipy_umfpack'

我可以使用从sourceforge下载的正式版成功import sklearn：http://sourceforge.net/projects/scipy/files/scipy/

【讨论】：

hmmm 我可能已经将它作为 Python XY 包的一部分安装了 code.google.com/p/pythonxy

你们两个希望我提供什么？告诉我我应该记下的答案，而不是我记下的内容。
