Please provide more information (versions info, how you do OCR - seem like you use some coding). I just tried tesseract (tesseract 5.0.0-alpha-416-g408d6) command line with tessdata_best and if work for me: tesseract unnamed.png - Warning: Invalid resolution 0 dpi. Using 70 instead. Estimating resolution as 497 Calibrations
