iOS - Tesseract - unable to read cube language model Cube ERROR (CubeRecoContext::Create): unable to init CubeRecoContext object



I am trying to make a Japanese OCR app. I am getting this error while i try to initialize Tesseract. Below are my code:


Japanese


OCR


Tesseract


if let tesseract = G8Tesseract(language: "eng+jpn")
tesseract.engineMode = .tesseractCubeCombined
tesseract.pageSegmentationMode = .auto
tesseract.image = image.g8_blackAndWhite()
tesseract.recognize()
textView.text = tesseract.recognizedText



Finally i figured out that i don't have cube files and i couldn't find searching them on github and other's site . Can anyone give me any link where i can find cube files for other language ???

Cube files are not available for all language. As i used


tesseract.engineMode = .tesseractCubeCombined



the above code, it will try to use both cube file and regular .traineddata file . To solve this problem , i had to replace the above code as below and add only the langdata as .traineddata format for the specific language under a folder named tessdata


.traineddata


langdata


.traineddata


tessdata


tesseract.engineMode = .tesseractOnly

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

Creating a leaderboard in HTML/JS

Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]&g
