小编Spa*_*r0i的帖子

好的,我在Android Studio 3.0中创建了一个全新的项目.Gradle构建在这个新实例化的项目中工作正常,直到我在我的模块中插入以下行build.gradle

dependencies {
    ...
    compile 'com.github.gabrielemariotti.cards:cardslib-core:2.1.0'
    compile 'com.github.gabrielemariotti.cards:cardslib-cards:2.1.0'
    compile 'com.github.gabrielemariotti.cards:cardslib-recyclerview:2.1.0'
}

这是我在构建日志中遇到的错误

/home/sparker0i/.gradle/caches/transforms-1/files-1.1/appcompat-v7-26.0.1.aar/e06e09188fb79d4d895b39247477d1c1/res/values/values.xml
Error:(246, 5) resource android:attr/foregroundInsidePadding is private

当我双击它时,我得到一个values.xml文件(合并一个),指针所在的位置

<dimen name="abc_action_bar_content_inset_material">16dp</dimen>

我的最低SDK版本是16,目标SDK是26.我使用的是Android Studio 3.0 Beta 2,构建工具版本是26.0.1.Gradle插件3.0.0-beta2.

我敢打赌这是因为有一个稍微过时的Cardslib库.有没有办法解决这个问题？(从依赖项中删除这些行工作正常)

环境：Spark 2.3.0、Scala 2.11.12、Kafka（无论最新版本是什么）

我有一个安全的 Kafka 系统，我正在尝试将 Spark Streaming Consumer 连接到该系统。以下是我的build.sbt文件：

name := "kafka-streaming"\nversion := "1.0"\n\nscalaVersion := "2.11.12"\n\n// still want to be able to run in sbt\n// https://github.com/sbt/sbt-assembly#-provided-configuration\nrun in Compile <<= Defaults.runTask(fullClasspath in Compile, mainClass in (Compile, run), runner in (Compile, run))\n\nfork in run := true\njavaOptions in run ++= Seq(\n    "-Dlog4j.debug=true",\n    "-Dlog4j.configuration=log4j.properties")\n\nassemblyMergeStrategy in assembly := {\n    case "META-INF/services/org.apache.spark.sql.sources.DataSourceRegister" => MergeStrategy.concat\n    case PathList("META-INF", _*) => MergeStrategy.discard\n    case _ => MergeStrategy.first\n}\n\nlibraryDependencies ++= Seq(\n    "org.apache.spark" %% "spark-core" % "2.3.0",\n    "org.apache.spark" …

附注。请不要指出我将 Keras 模型直接转换为 tflite，因为我的 .h5 文件将无法直接转换为 .tflite。我以某种方式设法将我的 .h5 文件转换为 .pb

我已经按照这个Jupyter notebook 使用 Keras 进行了人脸识别。然后我将我的模型保存到一个model.h5文件中，然后model.pb使用这个.

现在我想在 Android 中使用我的 tensorflow 文件。为此，我需要使用 Tensorflow Lite，这需要我将模型转换为某种.tflite格式。

为此，我试图在此处遵循官方指南。正如你在那里看到的，它需要input_array和output_array数组。如何从我的model.pb文件中获取这些内容的详细信息？

这是我在下面给出的代码.尽管创建了通知频道,但无法在Android O上创建任何通知.

private void weatherNotification(WeatherInfo weather) {
    Intent intent = new Intent(this, WeatherActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);

    String temperatureScale = prefs.getUnits().equals("metric") ? getString(R.string.c) : getString(R.string.f);
    String speedScale = prefs.getUnits().equals("metric") ? getString(R.string.mps) : getString(R.string.mph);

    String temperature = getString(R.string.temperature , weather.getMain().getTemp() , temperatureScale);
    String city = getString(R.string.city , weather.getName() + ", " + weather.getSys().getCountry());
    String wind = getString(R.string.wind_ , weather.getWind().getSpeed(), speedScale);
    String humidity = getString(R.string.humidity , weather.getMain().getHumidity());
    String pressure = getString(R.string.pressure, weather.getMain().getPressure());

    String data = city + "\n" + …

附注。有一个类似的问题在这里，但毕竟是在MVN和我的项目是在SBT。

首先，一些必需的信息：

• Spark 安装版本：2.4.0
• Scala 安装版本：2.11.12

我正在尝试在 IntelliJ IDEA 中运行这个项目，我的build.sbt看起来像：

name := "kafka-latest-spark-streaming"

version := "0.1"

scalaVersion := "2.11.12"

libraryDependencies ++= Seq(
    "org.apache.spark" %% "spark-sql" % "2.4.0" % "provided",
    "org.apache.spark" %% "spark-sql-kafka-0-10" % "2.4.0" % "provided",
    "org.apache.kafka" % "kafka-clients" % "0.11.0.1"
)

主要应用程序代码与教程中的代码相似，除了我必须进行一些导入才能使隐式$工作像工作一样。当我尝试通过右键单击并选择运行 scala 文件时Run 'Main'，它会引发以下错误：

我有一个vector<int>::iterator和一个vector<int>::reverse_iterator如图所示：

vector<int>::iterator start = array.begin();
vector<int>::reverse_iterator end = array.rend();
while (true)
{
    if (*start == *end && start <= end)
    {
        start++;
        end++;
    }
}

在 while 循环中，我必须检查 start 和 end 处的值是否相等以及 start 没有越过 end。这样做start <= end是给我错误。有人可以指导我通过正确的方法吗？

错误：

开始 <= 结束。二元运算符 '<=' 不能应用于 vector::iterator 和 reverse_iterator 类型的表达式。

我有一个看起来像这样的目录结构（两个文件夹都具有node_modules可用）

- task1
     - src
          - shorten.js
- task2
     - src
          - api.js
          - server.js

在shorten.js我有两个功能，即shorten(url)和checkLink(url)。在文件末尾，我有一些东西module.exports = shorten。

在api.js，我有一条线const shorten = require("../../task1/src/shorten");。如果仅shorten使用参数进行调用，就没有问题，但是当我尝试以checkLink类似方式进行调用时，问题就来了。

为了能够checkLink在task2的api.js内部调用，我该怎么办？

我正在尝试在我的android应用程序中实现MVVM体系结构。我也用Kotlin。

这是我的绑定适配器类：

class BindingAdapter {
    companion object {
        @JvmStatic @BindingAdapter("app:visibleGone") fun showHide(view: View, show: Boolean) {
            view.visibility =
                    if (show)
                        View.VISIBLE
                    else
                        View.GONE
        }
    }
}
