现在我想用特定字体训练tesseract阿拉伯语
根据{{3}}
您必须先创建数据，然后才能创建数据
此命令用于创建训练数据和评估列表
$TRAINING/tesstrain.sh --fonts_dir $FOLDER/simplified-arabic --lang ara --linedata_only \
--noextract_font_properties --langdata_dir $FOLDER \
--tessdata_dir $FOLDER/arabox/tessdata \
--fontlist "Simplified Arabic Bold" --output_dir $FOLDER/araeval
这是输出

我不明白那是什么？
使用lstm文件进行训练本身
$TRAINING/lstmtraining --debug_interval 0 --max_iterations 1 \
--traineddata $FOLDER/arabox/tessdata/ara.traineddata \
--net_spec '[1,36,0,1 Ct3,3,16 Mp3,3 Lfys48 Lfx96 Lrx96 Lfx256 O1c111]' \
--model_output $OUTPUT/base --learning_rate 20e-4 \
--train_listfile $FOLDER/araeval/ara.training_files.txt \
--max_iterations 5000 &>$OUTPUT/basetrain.log
它进入编码无限循环can't encode the character
根据文件
必须提供大胆的元素。其他是可选的，但如果提供任何dawgs，还必须提供标点符号dawg。我们提供了一个新工具
combine_lang_data，用于从traineddata和可选的单词列表中创建一个unicharset启动器。
