英文:
Tesseract Fatal error encountered!" == NULL:Error:Assert failed:in file globaloc.cpp, line 75
问题
1 - 我在 GitHub 上下载了 tesdata，链接为 https://github.com/tesseract-ocr/tessdata
2 - 解压缩文件夹，并将路径传递给 Tesseract 类
3 - 运行应用程序时显示以下错误

运行应用程序时显示以下错误
执行的代码片段
public class TesseractOcrTest {
private final String tesseractPath = "/home/tessdata/";
@Test
public void shouldReturnTrueIfRunOcrEquals() throws Exception {
String result = new TesseractOcr(tesseractPath).runOcr("bw_HighResolution_en.jpeg").trim();
assertEquals(
"Optical Character Recognition in Java\nis made easy with the help of Tesseract", result);
}
}
错误
Error: Illegal Parameter specification!
"Fatal error encountered!" == NULL:Error:Assert failed:in file globaloc.cpp, line 75
#

注意：当我将路径从 tesdata 更改为操作系统安装路径（private final String tesseractPath = "/usr/share/tesseract-ocr/4.00/tessdata/";），我可以完美地运行。如果我指向从 GitHub 下载的 tesdata，它就无法工作。
我做错了什么？从 GitHub 下载后，是否需要进行其他配置？
英文:
1 - I downloaded tesdata on the git hub https://github.com/tesseract-ocr/tessdata
2 - Extract the folder and passed the path to the Tesseract class
3 - When running the application the following error is displayed

Note: When I change the path from tesdata to the OS installation path (private final String tesseractPath = "/usr/share/tesseract-ocr/4.00/tessdata/";) I can do it perfectly. It just doesn't work if I point to the tesdata downloaded from the git hub.
What am I doing wrong? When downloaded from github do you need to do any more configuration?

你可能使用了不兼容的语言数据。对于当前的Tesseract版本，请使用随Linux发行版提供的tesdata_best或tesdata_fast，其文件大小可通过验证进行确认。

英文:
You've probably used incompatible language data. For the current Tesseract verion, use tessdata_best or tessdata_fast, which comes with Linux distros. (You can verify by checking the file size.)

Sure, here's the translated text:
- 确保您只安装了一个版本的Tesseract。
- 首先检查您使用的Tesseract版本（已安装的版本）。使用最新版本（4.x或5 alpha）。
- 使用Tesseract可执行文件而不是包装器进行OCR测试 - 它可以提供更多信息以找到问题。
英文:
- Make sure you have installed only one version of tesseract
- Fist check with version of tesseract you used (installed). Use the latest version (4.x or 5 alpha)
- Test OCR with tesseract executable instead of wrapper - it can provide more information for finding problem.
