我是使用sphinx的新手,第一次为python项目做文档.如何在sphinx文档中嵌入图像？

我正在运行容器hypriot/rpi-busybox-httpd

我正在尝试ssh到docker容器:但是它给出了错误:

pi@raspberrypi:~ $ docker exec -it cc55da85b915 bash
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"bash\": executable file not found in $PATH"

pi@raspberrypi:~ $ docker exec -it cc55da85b915 sh
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"sh\": executable file not found in $PATH"

我马上做的吗？

我想添加一个右键菜单来删除,重命名或打开QTAbleView单元格中每个单元格中的图像,我试过,发现每个人都试图将菜单添加到tableview中的标题,我试过下面但是看起来似乎不在下面的代码中工作..

class GalleryUi(QtGui.QTableView):
    """ Class contains the methods that forms the
        UI of Image galery
    """
    def __init__(self, imagesPathLst=None, parent=None):
        super(GalleryUi, self).__init__(parent)
        self.__sw = QtGui.QDesktopWidget().screenGeometry(self).width()
        self.__sh = QtGui.QDesktopWidget().screenGeometry(self).height()
        self.__animRate = 1200
        self._imagesPathLst = imagesPathLst
        self._thumb_width = 200
        self._thumb_height = self._thumb_width + 20
        self.setUpWindow(initiate=True)

        self._startControlBar()

        self._connections()

    def contextMenuEvent(self, event):

        index = self.indexAt(event.pos())
        menu = QtGui.QMenu()
        renameAction = QtGui.QAction('Exit', self)
        renameAction.triggered.connect(self.close)
        self.menu.addAction(renameAction)
        self.menu.popup(QtGui.QCursor.pos())

    def closeEvent(self,event):
        # in case gallery is launched by Slideshow this is not needed
        if hasattr(self, 'bar'):
            self.bar.close()

嗨,我在OSx Mavericks上,使用python 2.7和pip版本6.0.8以及setuptools版本12.2.

当我尝试安装我的项目时,我收到警告消息,但安装成功

$ python setup.py install --user

如果我使用distutils我得到下面的消息,可能它的设置没有kwarg entry_points./Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/distutils/dist.py:267:UserWarning:未知发行选项:'entry_points'warnings.warn(msg)

但是当我尝试使用以下方式使用pip安装时,我收到以下错误消息并且安装不会继续:

$ pip install --user --editable .

如果我使用pip即使我有distutils安装导入我得到以下错误消息.

如何使用golang在浏览器中临时打开网页？

就像这里是如何在 python中使用HTTPServer完成的.

在设计器中,当我右键单击一个小部件时,我点击提升到我得到这个窗口.请参见下面的截图.

我从未使用过这个功能.基本上,头文件让我很困惑.它是为了什么？这是否意味着我可以在这种情况下创建一个新类,继承QLineEdit并为其添加更多方法？推广的班级名称是什么？

所以我开始使用Pylint,但由于我使用制表符而不是空格,它给我作为警告,因为一些方法来自基类,也是'GalleryUi'的实例没有'setModel'成员,而它有QAbstractTableModel作为基类,我如何设置Pylint不考虑这些事情......

我最近从Mac OS X v10.7(Lion)升级了Mac OS X v10.9(Mavericks )!

我编写了这个服务，它使用 node.js 运行 TCP 服务器，将数据从微控制器获取到 mysql 服务器。

root@DietPi:~# sudo cat /lib/systemd/system/mysqlwifi.service 
 [Unit]
 Description=MySQL exampledb update
 After=multi-user.target
 After=network-online.target
 Wants=network-online.target

 [Service]
 Type=idle
 ExecStart=/usr/bin/node /home/dietpi/node_server/mysqlwifi.js > /home/dietpi/node_server/mysqlwifi.log 2>&1

 [Install]
 WantedBy=multi-user.target
root@DietPi:~#

由于此服务对于将数据推送到 mysql 至关重要，我希望它在失败时自动重新启动。我还想知道如何在每次失败或服务恢复正常时发送电子邮件。

我知道它的基本问题,但我有点困惑,可能是我忘记了什么.

我正在尝试将子菜单"预览"添加到QMenuBar()中的"工具"

到目前为止,这正是我想要做的

tools = fileMenu.addMenu('&Tools')
prevAction = QtGui.QAction('Preview',self)
prevInNuke = QtGui.QAction("Using &Nuke",prevAction)
tools.addAction(prevAction)
prevAction.addAction(prevInNuke)

但我想这不是添加子菜单的正确方法
