Python 为什么Tesseract'；s.traineddata文件在heroku中未显示，尽管已成功上载和提取？

我正在尝试通过heroku和Tesseract部署OCR应用程序

wget

ting

.traineddata

文件会导致错误，因此我决定将它们压缩到

.tar.gz

文件中，并将它们上传到自定义的buildpack中，应用程序将从中生成。但是，只有默认的

eng.traineddata

文件存在，而其他

.traineddata

文件以某种方式被删除。生成日志显示文件已成功提取。将生成日志粘贴到下面：

以下是

$TESSDATA\u PREFIX

目录中的

ls-as

命令的输出：

~$ ls -as $TESSDATA_PREFIX
total 22928
    4 .      4 ..  22920 eng.traineddata

用于自定义构建包。 我错过什么了吗
