I tried using version 4.0 by building it from source. However, I get following messages, and without much surprise, the output is totally bizarre.
Failed to load any lstm-specific dictionaries for lang eng-numCAPS!! Tesseract Open Source OCR Engine v4.00.00alpha with Leptonica Warning. Invalid resolution 0 dpi. Using 70 instead. Estimating resolution as 233 Output: *4JTX9T* I understand that the DPI message is there since older versions and I had it in 3.05 as well, the 'lstm-specific' message is probably from the training data file? Only other option is train/finetune on my own set? On Tuesday, March 27, 2018 at 1:37:36 PM UTC-7, shree wrote: > > Version mismatch. That traineddata is for 4.0. > > Wiki has pages for training.
