Python 导入scikit学习时出错

我正在尝试使用以下代码：

from matplotlib import pyplot as plt
from sklearn.datasets import load_iris
import numpy as np

我得到这个错误：

ImportError: No module named sklearn.datasets

然后我尝试安装scikit learn，但出现以下错误：

pip install -U scikit-learn
  File "<ipython-input-9-6d283b29f0f9>", line 1
    pip install -U scikit-learn
              ^
SyntaxError: invalid syntax


easy_install -U scikit-learn
  File "<ipython-input-10-59440c1e5ef6>", line 1
    easy_install -U scikit-learn
                         ^
SyntaxError: invalid syntax

我猜您正在尝试将这些命令放入Python命令行中。它们应该在您的操作系统终端中工作

Scikit学习包含在Canopy Basic not Express中

但正如@sashkello所指出的，您可以从OS命令行安装任何软件包，而不是此处所述的python命令行： 但是，根据您的操作系统和体验级别，您可能会发现这很困难，因为这个包不是纯Python

我的答案是为我特定的Python版本安装这个。

我的答案是为我特定的Python版本安装这个。

我在Windows上。你是说我需要打开一个命令提示符并运行这些命令？什么目录重要吗？是的，这就是我的意思。不管是哪个目录，我在Windows上。你是说我需要打开一个命令提示符并运行这些命令？什么目录重要吗？是的，这就是我的意思。不管是哪个目录。当我在命令提示符下键入sys.prefix时，它的内容是c:\\users\\dom\\appdata\\local\\enthunk\\corporation\\user，但当我尝试easy\u install pip时，它会显示SyntaxError:无效语法并指向easy\u install pip中的最后一个p。我做错了什么？@user1477388:正如萨什凯洛所说，乔纳森用粗体字写了出来！，您正在Python控制台中键入该命令。您必须在shell中运行该命令。@DSM我在命令提示符下运行了该命令，即当我运行并键入cmd时。@user1477388:否，语法错误：无效语法是Python错误消息，而不是shell错误消息。因此，要么是您将其键入Python，要么是您给了我们错误的错误消息。@DSM谢谢，很抱歉我在启动Python的CMD中键入Python。无论如何，我安装了pip，但是，我在尝试安装scikit learn时出错。我在编辑问题时发布了相关日志。当我在命令提示符中键入sys.prefix时，它显示为c:\\users\\dom\\appdata\\local\\enthund\\corporation\\user，但当我尝试easy\u install pip时，它显示SyntaxError:无效语法并指向easy\u install pip中的最后一个p。我做错了什么？@user1477388:正如萨什凯洛所说，乔纳森用粗体字写了出来！，您正在Python控制台中键入该命令。您必须在shell中运行该命令。@DSM我在命令提示符下运行了该命令，即当我运行并键入cmd时。@user1477388:否，语法错误：无效语法是Python错误消息，而不是shell错误消息。因此，要么是您将其键入Python，要么是您给了我们错误的错误消息。@DSM谢谢，很抱歉我在启动Python的CMD中键入Python。无论如何，我安装了pip，但是，我在尝试安装scikit learn时出错。我在我的编辑中发布了相关日志。
