Hi Clyde, Nearly there. Try giving the full path to the eng.traineddata file. So this command:
combine_tessdata -u "C:\Program Files\Tesseract-OCR\eng.traineddata" eng. (that path may be slightly wrong as I can't remember exactly where the eng.traineddata is in the Windows install - find it and correct it as necessary) Nick On Sun, Sep 22, 2013 at 11:38:44PM -0700, clyde wrote: > Hello Nick White! > > when i try to unpack the eng.traineddata > command: combine_tessdata -u eng.traineddata eng. > > i got an error message: > > Error opening data file eng.traineddata > Please make sure the TESSDATA_PREFIX environment variable is set to the parent > d > irectory of your "tessdata" directory. > Extracting tessdata components from eng.traineddata > > > I did check the environment variable of TESSDATA_PREFIX. > see attach image.. > > > [env] > > thank you...i hope for your response.. > > > > Noong Biyernes, Hulyo 20 2012 17:03:41 UTC+8, si Nick White ay sumulat: > > Hi Nikola, > > I suggest you don't try training it.
