小编Pab*_*ada的帖子

我正在尝试使用 reChart 渲染一个条形图以使其容器 100% 适合：

http://recharts.org/#/en-US/api/ResponsiveContainer

 <div className="question">
    <div className="question-container">
        <ResponsiveContainer width="100%" height="100%">
            <BarChart   layout="vertical" data={rows}
                      margin={{top: 5, right: 30, left: 20, bottom: 5}}>

                <YAxis axisLine={false} tickLine={false} width={400} dataKey="name" type="category">
                </YAxis>
                <Bar dataKey="valuePre" fill="#00a0dc" label={<Text scaleToFit={true} verticalAnchor="middle" />}/>
                <Bar dataKey="valuePost" fill="#c7c7c7"  label={<Text verticalAnchor="middle" />}/>

            </BarChart>
        </ResponsiveContainer>
    </div>
</div>

当我添加 ResponsiveContainer 组件时，数据停止呈现。而且只要我取出 ResponsiveContainer 并设置 BarChart 组件的宽度和高度，我就可以再次看到条形图。

谁能帮我找出我做错了什么？

这是一个解决问题的方法：

我开始在Pycharm IDE中使用Django并成功配置了我的第一个项目.

但是,我尝试向Pycharm添加一个新的现有项目,当我尝试更改Run Configuration以使用我的secondProject(GuatepediaLocal)的manage.py时,我没有选择在下拉菜单中选择它.当我尝试运行该项目时,它会继续运行PollSite manage.py runserver而不是GuatepediaLocal的manage.py runserver

任何人都可以帮我解决这个问题并在pycharm上配置已经存在的Django项目吗？

我在docker容器内的jenkins上执行管道.此管道调用另一个执行ansible playbook的docker-compose文件.执行playbook的服务称为agent,定义如下:

我正在尝试提取 wav 文件的一些特征，我有这个：

我正在使用 pyAudioAnalysis 库的特征提取工具：

https://github.com/tyiannak/pyAudioAnalysis/wiki/3.-特征提取

问题是我遇到了reshape()numpy 函数的错误。我遵循 wiki 中如何使用特征提取器的指南，如下所示：

[Fs, x] = audioBasicIO.readAudioFile('13 Clock in the Morning - Waiters the  Free Music Archive (No Copyright Music).wav')
F = audioFeatureExtraction.stFeatureExtraction(x, Fs, 0.050 * Fs, 0.025 * Fs)

这是我得到的错误：

我有一个人模型,它与会议模型有一个belongsTo关系.我在做查询

Person.find({include:['meetings']})

这给了我一个像这样的结果:

    person:{
        name:"person 1",
        age: 15
        meeting:{
            name: "The meeting",
            date:"June 26, 2019 11:13:00"
        }
    }

我想要做的是在会议日期之前订购查找功能的结果.有什么方法可以在单个查询中实现这一点吗？

我试过这个:

Person.find({include:['meeting'],order:"meeting.date DESC"})

但是在尝试这个时服务器崩溃了.谁能帮我实现这个目标？

我在 angular-chart 上有以下图表：

<canvas id="line" class="chart chart-line" chart-data="data"  chart-colors="colors"
        chart-series="series" chart-options="options">

使用此选项：

$scope.options = {
  type:'line',
  tooltips: {
    enabled: false
  },
  showTooltips: false,
  hover: {mode: null},
  scales: {
    xAxes: [{
      type:"time"
    }]
  }
};

我通过这样的 websocket 更新数据：

channel.on("create:entry", function (msg) {
  // Before updating the data, set the new time to the current time
  $log.log("received entry");
  $log.log(msg);
  // Refetch the data points
  $scope.data[0].push(
    {
      x: new Date(),
      y: msg.sonnar
    });
  vm.current = msg.sonnar;
