eng_pcb.traineddata is a traineddata starting with eng.traineddata i did lstm training to improve the detection of ocr rather than the recognition. i used tesstrain git repo.
final error: couldn't find the legacy components in eng_pcb.traineddata On Monday, April 22, 2024 at 6:43:54 PM UTC+2 zdenop wrote: > No, you are not using best float tessdata files from: > https://github.com/tesseract-ocr/tessdata_best/blob/main/eng.traineddata > There is nothing like eng_pcb.traineddata.
