我刚刚在ubuntu上重新安装了最新的tensorflow:

$ sudo pip install --upgrade https://storage.googleapis.com/tensorflow/linux/cpu/tensorflow-0.7.1-cp27-none-linux_x86_64.whl
[sudo] password for ubuntu: 
The directory '/home/ubuntu/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

我的应用使用Firebase同步和恢复数据.我使用该setValue:withCompletionBlock:方法插入,更新和删除Firebase对象.只要存在CoreData保存,就会调用此方法,从而将所有本地更改同步到Firebase

- (void) setValue:(id)value withCompletionBlock:(void (^)(NSError* error, Firebase* ref))block;

现在同步将所有本地数据上传到firebase,而restore则使用firebase数据替换本地数据.

- (void) observeSingleEventOfType:(FEventType)eventType withBlock:(void (^)(FDataSnapshot* snapshot))block;

我观察FEventTypeValue并使用它FDataSnapshot来从Firebase获取数据并恢复本地数据.

所以一切都适合我,直到我开始persistence使用Firebase.

[Firebase setOption:@"persistence" to:@YES];

现在persistence,当我打开时,当我更新时,比如将对象插入Firebase,然后恢复,恢复插入前的数据.即没有恢复新插入的对象.但是,如果我再次恢复,则会恢复插入的对象.删除对象时会发生同样的事情.当我第一次恢复时,删除的对象重新出现,当我再次恢复时,删除的对象消失.我可以看到通过Firebase数据视图正确插入和/或删除了Firebase对象.

我不确定我在这里做错了什么.我恢复时只有问题.我认为Firebase缓存导致此恢复问题.我正在考虑在恢复之前清除Firebase缓存.我的问题是

1. 在恢复之前清除缓存是一个好方法吗？
2. 如果是,请问如何清除Firebase缓存？
3. 如果不是,您能否建议我恢复数据的最佳方法.

我将Android Studio Canary从2更新为3(当前版本),现在我在构建项目时遇到错误:

我正在尝试安装支持GPU的tensorflow.

我尝试了以下链接中的信息

https://www.tensorflow.org/install/install_windows

1. CUDA®Toolkit8.0
2. cuDNN v6.0
3. 具有CUDA Compute Capability 3.0的GPU卡 - GeForce 940MX

然后用来pip3 install --upgrade tensorflow-gpu安装tensorflow.

但是在尝试导入tensorflow时我收到以下错误.

    Traceback (most recent call last):
      File "C:\Research\Python_installation\lib\site-packages\tensorflow\python\platform\self_check.py", line 75, in preload_check

    During handling of the above exception, another exception occurred:

我正在遵循谷歌代码实验室的指示

当我运行以下命令时,我遇到了一些错误.

python -m scripts.retrain \

    --output_labels=tf_files/retrained_labels.txt \
    --architecture="${ARCHITECTURE}" \

错误是

我需要训练一个双向LSTM模型以识别离散语音（单个数字从0到9），我已经录制了100个扬声器的语音。接下来我该怎么办？（假设我将它们分成单个的.wav文件，每个文件包含一个数字）我将使用mfcc作为网络功能。

此外，如果我要使用支持CTC（连接主义者时间分类）的库，我想知道数据集的差异。

Android Studio 2.1,Java V8 Update 91,Gradle 2.1.0.

我知道这里已经多次提出这个问题,但没有一个推荐解决方案可行.

在编译完成后准备在Emulator上运行时,我的IDE会在R.id属性上给出错误.即使我不对文件进行任何更改,每个Java文件也会突然出现相同的错误.

我试图创建一个新项目,看看事情是否不同但错误仍在继续.在我看来,这可能是内部错误.即使我刚刚更新我的IDE.

Java文件;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_science);

    list_View = (ListView) findViewById(R.id.maintable); 
    String[] Days = new String[] { "Sunday", "Monday", "Tuesday", "Wednesday","Thursday", "Friday", "Saturday"};
    dayList.addAll(Arrays.asList(Days));
    adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, dayList);
    list_View.setAdapter(adapter);

    NfcAdapter nfc = NfcAdapter.getDefaultAdapter(this);

    if (nfc.isEnabled()) {
        adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, dayList);
        Toast.makeText(this, "NFC turned ON", Toast.LENGTH_SHORT).show();
    }

    else {
        Toast.makeText(this, "Please turn On NFC", Toast.LENGTH_SHORT).show();
    }

}

这R是错误.
