用python3.5 pip安装Numpy

Question

我有很多探针来安装numpy软件包。 当我执行pip commande

pip install numpy

我收到以下错误

连接被'ConnectTimeoutError（，'与pypi.python.org的连接超时。（connect timeout = 15）'）断开连接后重试（Retry（total = 4，connect = None，read = None，redirect = None））： / simple / numpy /找不到满足numpy要求的版本（来自版本：）找不到numpy的匹配发行版

当我使用easy_insall命令时，出现以下错误

搜索numpy超时-可能找不到某些软件包！ 找不到'numpy'的索引页（可能拼写错误？）扫描所有软件包的索引（这可能需要一段时间）读取https://pypi.python.org/simple/在https：//pypi.python上下载错误.org / simple / ：超时-可能找不到某些软件包！ 未找到有关numpy错误的本地软件包或下载链接：找不到Requirement.parse（'numpy'）的合适发行版

当我采用手动包装时

python setup.py install

我收到以下错误：

请需要帮助。

Answer 1

您可以随时下载Numpy安装程序

Answer 2

pip错误显示您有pip连接问题。 我认为您尝试运行pip安装时未正确设置代理。 请检查此问题 。 您可以尝试pip的--proxy选项。 否则，我不建议对numpy进行任何手动安装。

Answer 3

也许原因是网络，您可以再试一次。 （对我有用）
