Tesseract无法加载任何语言问题
我在互联网上搜索，然后尝试将我的tessdata_prefix更改为导出tessdata_prefix =/usr/local/local/share/tessdata或... share/tessract-ocr/4.00或5/tessdata和tessdata and tesseract/tessdata* 。我在所有这些位置都有Eng.TrainedData文件。但是我仍会遇到此错误，我尝试从Github更改训练的数据文件。但是我仍然遇到这个错误。
这是我的代码
#include <string>
#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main(){
cv::Mat image;
string outText;
image = cv::imread("text.png",cv::IMREAD_COLOR);
tesseract::TessBaseAPI *api = new tesseract::TessBaseAPI();
api->Init(NULL, "eng", tesseract::OEM_LSTM_ONLY);
api->SetPageSegMode(tesseract::PSM_AUTO);
api->SetImage(image.data, image.cols, image.rows, 3, image.step);
outText = string(api->GetUTF8Text());
cout << outText;
api->End();
}
我的makefile，
CC = g++
PROJECT = main
SRC = main.cpp
LIBS = `pkg-config --cflags --libs opencv4 tesseract`
$(PROJECT) : $(SRC)
$(CC) $(SRC) $(LIBS) -o $(PROJECT)
这是错误消息

Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.

I search on internet and I try change my TESSDATA_PREFIX to export TESSDATA_PREFIX=/usr/local/share/tessdata or ...share/tessract-ocr/4.00 or 5/tessdata and tesseract/tessdata** this paths is not working for me. I have eng.traineddata file on all this locations. But I'm still getting this error and I try change traineddata file from github. But I'm still getting this error.
Here is my code
#include <string>
#include <tesseract/baseapi.h>
#include <leptonica/allheaders.h>

api->SetPageSegMode(tesseract::PSM_AUTO);
api->SetImage(image.data, image.cols, image.rows, 3, image.step);
outText = string(api->GetUTF8Text());
cout << outText;
api->End();

在
init（）方法中设置第一个参数，以指定“ Eng.trainedData”的文件路径并将第三参数设置为
oem_default在以下之前：
至：
ex）
set the first parameter in
Init()method to specify the file path that "eng.traineddata" locatedand set the 3rd parameter to
OEM_DEFAULTbefore :
