我试图运行朱古力上Linux Ubuntu.安装后,我在gpu中运行caffe,错误是

Aborted (core …它应该是直截了当的,但我不确定哪里出了问题.我试着抓住TextViewwith 上的点击:
public void runNextTask(){
final View addView = getLayoutInflater().inflate(R.layout.addnewtracker, null);
final TrackerInfo newInfo = new TrackerInfo();
//set up for model selection
TextView modelTextview = (TextView)addView.findViewById(R.id.modelEdit)
modelTextview.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
}
你的XML TextView是:
<TextView
android:id="@+id/model"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/Tracker_model"
android:clickable="true"
android:onClick="onClick"/>
但是当我点击TextView它时,它不会进入onClick()方法.我错过了什么？
谢谢
我有错误No module named __future__.我使用tensorflow,它有Python2.7.一旦我运行程序,我得到错误,如下所示.
import tensorflow
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/coie/tensorflow/local/lib/python2.7/site-packages/tensorflow/__init__.py", line 19, in <module>

ImportError: No module named __future__
如何将未来安装到tensorflow的Python中？
我正在尝试使用Motion JPEG流媒体流式传输jpgs.我需要安装包libv41-dev作为必需的库,当我安装时sudo apt-get install libv41-dev,我得到Unable to locate package libv41-dev错误.为什么找不到那个包裹？我在谷歌搜索libv41-dev,没有太多的信息出来.该库是linux/videodev.h文件所必需的.谢谢

for(;;){ …关于这个主题有很多讨论.但它们都不适合我.我实现了一个定制的ListView用ImageView在ListView和ListView从扩展ListFragment.我的ImageView是可点击的,因此当用户单击ImageView时,将激活Camera活动并使用捕获的图像更新ImageView.XML如下所示
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

现在我需要区分用户的列表项目或ImageView的点击.我设置onListItemClick了可以捕获用户单击ListView中的列表项,但是当我单击ImageView时,它不起作用.如何检测用户何时单击ImageView.我的ListFragment类如下所示.
public class MyListFragment extends ListFragment {
private customList_Adaptor adapter;
private static final int CAMERA_REQUEST = 0;
private static final int RESULT_OK = 0;
private static MyListFragmentInterface mCallback = null;
static Context …我开发 iOS 应用程序，它使用相机。AVCaptureDeviceInput 用于与相机连接。我检查了授权状态为
- (void)checkDeviceAuthorizationStatus
{
NSString *mediaType = AVMediaTypeVideo;
[AVCaptureDevice requestAccessForMediaType:mediaType completionHandler:^(BOOL granted) {
if (granted)
{
//Granted access to mediaType
[self setDeviceAuthorized:YES];
}
else
{
//Not granted access to mediaType
dispatch_async(dispatch_get_main_queue(), ^{
[[[UIAlertView alloc] initWithTitle:@"AVCam!"
message:@"AVCam doesn't have permission to use Camera, please change privacy settings"
delegate:self
cancelButtonTitle:@"OK"
otherButtonTitles:nil] show];
[self setDeviceAuthorized:NO];
});
}
}];
}
当我启动应用程序时，为什么它不询问用户访问相机的权限？因此该应用程序不会出现在设置/隐私/相机中以手动允许访问相机。然后显示此错误"AVCam doesn't have permission to use Camera, please change privacy settings"并且应用程序无法使用相机。
编辑：这意味着未经用户许可，应用程序不得访问相机。不仅是相机，相机胶卷也存在同样的问题。
所有这些事情都是在我在“设置/重置/恢复所有设置”中重置设置后发生的。在此之前，该应用程序运行良好。
