Question

我在virtualenv中为theano安装了scipy，它在安装开始后就失败了。并说它失败了，错误代码为-11。任何人都可以帮我这个，错误代码11是什么？

以下是从运行命令开始时的错误的完整跟踪：

(dl)[haohan@sirius deeplearning]$ pip install theano
Requirement already satisfied (use --upgrade to upgrade): theano in ./dl/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): numpy>=1.5.0 in ./dl/lib/python2.7/site-   packages (from theano)

为了方便阅读，我将第二行打破成几行我认为这很奇怪，安装开始后几乎没有发生错误，我只是使用pip成功安装numpy，所以它不太可能是pip的问题。那么，问题出在哪里？我该如何解决？

它可能与系统有关吗？但我想我无法打印出系统信息，因为我没有sudo权限......

可能因为我们的群集太旧了吗？这是我能想到的唯一解释。

非常感谢！

您是否尝试过更新setuptools？

pip install --upgrade setuptools

然后再次尝试安装theano。

当我在开发自己的包时遇到此问题时，根本原因是setup.py中的导入。我改变了setup.py导入的内容，然后才起作用。也许theano的设置是导入包含不兼容版本的软件包？

如果通过更新软件包或编辑设置中的导入来解决问题，您可以尝试使用vvv标志进行调试以获取更多信息，如pip install -vvv theano中所示。

至于你看到的错误代码：

负值-N表示孩子被信号终止 N（仅限Unix）

https://docs.python.org/3/library/subprocess.html#subprocess.Popen.returncode

代码11表示* nix中的段错误，但os.strerror(11)报告＆＃34;资源暂时不可用＆＃34;。因为当我尝试使用python setup.py egg_info时我得到了段错误，所以我打赌它是11的第一个（段错误）定义。

如果您的段错误转储核心，如果您正在使用systemd，则可能在/var/lib/systemd/coredump/。 https://unix.stackexchange.com/a/349433/183163 如果找不到核心，请检查ulimit -c。如果它报告0，请运行ulimit -c unlimited以启用核心转储。您可以通过ls -rtd /var/lib/systemd/coredump/* | tail -1

获取最新转储文件的完整路径

要阅读转储，您可以使用gdb。例如：

gdb python /var/lib/systemd/coredump/core.python.6146.f06ba728dae74cfbbaf80acb8d392dd5.4477.1524677641000000.lz4

pip install scipy，失败，错误代码为-11
