无法通过pip

时间：2016-07-02 19:31:32

标签： python python-2.7 pip homebrew

我正在尝试运行需要数据集python包的脚本。我通过调用：

尝试使用pip来安装这个失败

pip install datasets

我知道这没有用，因为当我运行脚本时，我收到消息：

Traceback (most recent call last):
  File "lda.py", line 2, in <module>
    import lda
  File "/Users/deepthought/lda.py", line 3, in <module>
    import datasets
ImportError: No module named datasets

我已经通过自制软件安装了python。

当我运行pip install datasets时，我收到错误：

Command "python setup.py egg_info" failed with error code 1 in /private/var/folders/ch/84cpkwc52zx0rsh4k5v4_7h40000gn/T/pip-build-gZWyT3/datasets/

我对脚本编写python或者在OS X的引擎下是相当新的，因此存在我错过了一些基本内容的风险。

我一直在研究和试图克服这个问题大约一个星期，包括在stackoverflow.com上查看类似的问题，并且在此期间没有超过这个阶段。我正在处理的其中一个教程告诉我编辑〜/ .profile

这样就是这样：

# The orginal version is saved in .profile.pysave
#PATH="/Library/Frameworks/Python.framework/Versions/3.5/bin:${PATH}"
#export PATH
export PATH=/usr/local/bin:/usr/local/sbin:$PATH

/ etc / paths包含：

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

我正在运行OS X El Capitan - 10.11.5（15F34） Python 2.7.11

Brew医生标记了多个项目，但我不知道是否值得修复所有项目：

如何通过安装数据集包来诊断问题？

更新

这是我正在尝试运行的脚本：

import sys
egg_path = '/usr/local/lib/python2.7/site-packages/datasets-0.0.9-py2.7.egg'
sys.path.append(egg_path)

import numpy as np
import lda
import datasets

X = lda.datasets.load_reuters()
vocab = lda.datasets.load_reuters_vocab()
titles = lda.datasets.load_reuters_titles()
X.shape
(395, 4258)
X.sum()
84010
model = lda.LDA(n_topics=20, n_iter=1500, random_state=1)
model.fit(X)  # model.fit_transform(X) is also available
topic_word = model.topic_word_  # model.components_ also works
n_top_words = 8
for i, topic_dist in enumerate(topic_word):
     topic_words = np.array(vocab)[np.argsort(topic_dist)][:-(n_top_words+1):-1]
     print('Topic {}: {}'.format(i, ' '.join(topic_words)))

使用pip install datasets我也无法正确安装此软件包。似乎这个特定包中存在错误。

DESCRIBE.rst 文件完全丢失。要解决此问题，只需从PyPi下载普通包。 https://pypi.python.org/pypi/datasets/0.0.9

然后调整setup.py 文件（删除说明）。

之后您需要使用python setup.py install进行安装。别忘了将已安装的软件包添加到Python路径中！

为此，我建议您将以下内容添加到脚本中。

import sys
egg_path = '__MODULE_PATH__/datasets-0.0.9-py3.5.egg'
sys.path.append(egg_path)
import datasets

否则，您也可以使用以下方式添加模块：

export PATH=__MODULE_PATH__:$PATH

或者，您也可以简单地从Github存储库中提取源代码，并将其包含在您的项目中。 https://github.com/realtimeweb/datasets

希望这对你的问题有所帮助。如果您有任何其他问题，请告诉我。

我刚刚在rapsberry pi上遇到了同样的问题，刚刚发现这个问题已得到修复，但错误来自缺乏ram来正确提取包裹。

您可以通过在ram中添加参数

来禁用缓存目录的创建来解决此问题 
--no-cache-dir

例如

pip2 install --user --no-cache-dir datasets

下载DataSets package straight from GitHub？
