我想要达到这样的效果- Reference Video 假设我有一个垂直视频(Dimension- 720x1280)。我想创建一个具有自适应背景的水平视频,就像我展示的视频一样。我已经写了一些读写文件的代码。 video_index = 0
cap = cv2.VideoCapture(videofiles[0])
# video resolution: 1920x1080 px
out = cv2.VideoWriter("video.mp4v",
cv2.VideoWriter_fourcc(*'MP4V')
我从这个YouTube视频()开始制作一个虚拟助手程序。我编写了基本的语音识别代码,但它对内部麦克风和外部麦克风的语音输入都不响应。当我运行程序时
import speech_recognition as sr
from gtts import gTTS
def recordAudio():
record=sr.Recognizer()
with sr.Microphone() as source:
print('Say something!')
audio=record.listen(source)
data=''

我正在尝试开发我的第一个Drupal 8模块,我不明白为什么在我的小枝模板中没有定义jQuery。
在我的块中,我调用控制器函数:
public function build() {
$config = $this->getConfiguration();
$slider = new OsTouchController;
return $slider->displaySlider($config['id']);
}
然后在控制器中:
public function displaySlider($slider_id) {
$o
因为我正致力于在Suse机器上自动化补丁过程。我想对包的状态生命周期有一个更清晰的印象。
首先,我试图列出可用的修补程序及其新版本,只需运行:
$ zypper list-updates

我有四节课
class A { //a base class
public:
A(ostringstream* os){ oss2=os; }
ostringstream* oss2;
};
class B : public A{ // a derived class
public:
B(ostringstream* os):A(os){};
};
class C { //class where oss is actually declared
public:
C(){};
ostringstream oss;
};
