linux - Tesseract 无法在 RHEL 8 上加载语言

Question

在 Redhat 8 上尝试测试 tesseract 时出现错误

tesseract --list-langs
Error opening data file /usr/local/share/tessdata/eng.traineddata
Please make sure the TESSDATA_PREFIX environment variable is set to your "tessdata" directory.
Failed loading language 'eng'
Tesseract couldn't load any languages!
List of available languages (2):
eng
tha

这里我的版本 tesseract 和其他包相关

tesseract --version
tesseract 4.1.1
 leptonica-1.80.0
  libjpeg 6b (libjpeg-turbo 1.5.3) : libpng 1.6.34 : libtiff 4.0.9 : zlib 1.2.11 : libwebp 1.0.0
 Found AVX2
 Found AVX
 Found SSE

我还添加了前缀

export TESSDATA_PREFIX=/usr/local/share/tessdata/
echo $TESSDATA_PREFIX
/usr/local/share/tessdata/

我还获得了原始的训练数据文件，例如组建议 https://groups.google.com/g/tesseract-ocr/c/KKTiag0VCFE/m/A4jpS6i6CwAJ

但仍然无法解决我的问题。请帮帮我谢谢！！！
