Example 1: string erase character c++ # include <iostream> # include <algorithm> # include <string> int main ( ) { std :: string s = "This is an example" ; std :: cout << s << '\n' ; s . erase ( 0 , 5 ) ; // Erase "This " std :: cout << s << '\n' ; s . erase ( std :: find ( s . begin ( ) , s . end ( ) , ' ' ) ) ; // Erase ' ' std :: cout << s << '\n' ; s . erase ( s . find ( ' ' ) ) ; // Trim from ' ' to the end of the string std :: cout << s << '\n' ; } Example 2: erase string c++ string & erase ( size_t pos = 0 , size_t len = npos ) ; /* pos Position of the first character to be erased. If this is greater than the string length, it throws out_of_range. Note: The first character in str is denoted by a value of 0 (not 1). len Number of characters to er...

Answer : In Tensorflow 2.0 you should be using hub.load() or hub.KerasLayer() . [April 2019] - For now only Tensorflow 2.0 modules are loadable via them. In the future many of 1.x Hub modules should be loadable as well. For the 2.x only modules you can see examples in the notebooks created for the modules here this function load will work with tensorflow 2 embed = hub.load("https://tfhub.dev/google/universal-sentence-encoder-large/3") instead of embed = hub.Module("https://tfhub.dev/google/universal-sentence-encoder-large/3") [this is not accepted in tf2] use hub.load()

Answer : Modify the background canvas before you begin the frame, not within the frame. To keep the effect of the color change local, you could use curly braces around the frame and that command, or \begingroup ... \endgroup . { \setbeamercolor{background canvas}{bg=violet} \begin{frame} % frame contents here \end{frame} } Put the \setbeamercolor command outside the frame. This will change the background colour for every subsequent frame. If you want to just change that slide, you can surround the frame and the command in {} Here's a complete example: \documentclass{beamer} \begin{document} \begin{frame}{A white frame} \end{frame} % Change all subsequent frames to violet \setbeamercolor{background canvas}{bg=violet!20} \begin{frame}{A violet frame} \end{frame} \begin{frame}{This frame is also violet} \end{frame} % But this frame only will be yellow: note { ... } around % the \setbeamercolor and the frame to limit the scope {\setbeamercolor{background canvas}{bg=ye...

Answer : You can use isMounted React pattern to avoid memory leaks here. In your constructor: constructor(props) { super(props); this._isMounted = false; // rest of your code } componentDidMount() { this._isMounted = true; this._isMounted && this.getImage(this.props.item.image); } in your componentWillUnmount componentWillUnmount() { this._isMounted = false; } While in you getImage() async getImage(img) { let imgUri = await Amplify.Storage.get(img) let uri = await CacheManager.get(imgUri).getPath() this._isMounted && this.setState({ image: { uri }, ready: true }) } A recommend approach to use Axios which is based cancellable promise pattern. So you can cancel any network call while unmounting the component with it's cancelToken subscription . Here is resource for Axios Cancellation From the React blog Just set a _isMounted property to true in componentDidMount and set it to false in ...

Answer : Ok, so I solved this, somehow in trying to build for the app store I changed the build config for the "run" scheme from debug to release.. and naturally release was using a distribution cert.. which wasn't (and can't be) installed on my device. I hate xcode 4. (this aspect of it :P) What is a scheme anyway? :S I have a solution as well. This happened to me last night with the exact same error. I had a program that was previously compiling and now that I am adding an update to my app, the same error was displayed. The problem is that I forgot to change my provisioning profile back to Developer. (You set it to Distribution when uploading your app to the App Store). Here are the settings for Xcode 4.6. In your app click Targets -> YourAppName -> Code Signing Identy. Change iPhone Distribution to iPhone Developer. Your app will now compile. 1- TARGETS -> click the app-> Build Setting-> Code Signing : Make sure that both ...

Example 1: using array map php array_map ( callable $callback , array $array1 [ , array $ ... ] ) : array Example 2: php map array function cube ( $number ) { return ( $number * $number * $number ) ; } $nums = [ 1 , 2 , 3 , 4 , 5 ] ; $cubed = array_map ( 'cube' , $nums ) ; Example 3: array map php The array_map() function sends each value of an array to a user-made function, and returns an array with new values, given by the user-made function. Tip: You can assign one array to the function, or as many as you like. Syntax array_map(functionname, array1, array2, array3, ...) Example Send each value of an array to a function, multiply each value by itself, and return an array with the new values: <?php function myfunction ( $val ) { return ( $val * $val ) ; } $a = array ( 1 , 2 , 3 , 4 , 5 ) ; print_r ( array_map ( "myfunction" , $a ) ) ; ?> Example 4: php array map $func = function cube ( $n ) { ...
