Hello I am now having trouble using the "mftraining" command to cluster ".tr" files. I've created traineddata for both of the box/img file pairs and .tr files individually and they have worked. I ran through all the steps again to put them together such as the "unicharset_extractor" for box0 box1 files and those were successful as well
When I tried to do "mftraining" with the .tr files, I got an error as showed below C:\Program Files (x86)\Tesseract-OCR>mftraining -U unicharset -O eng.unicharset eng.lucidaconsole.exp0.tr eng.lucidaconsole.exp1.tr Reading eng.lucidaconsole.exp0.tr ... lucidaconsole has no defined properties. Reading eng.lucidaconsole.exp1.tr ... Writing Merged Microfeat ...Class->NumConfigs == this- >fontset_table_.get(Class- >font_set_id).size:Error:Assert failed:in file .\intproto.cpp, line 1268 mftraining will then crash. How would I be able to bring all of these .tr files together? I've tried different orders such as: C:\Program Files (x86)\Tesseract-OCR>mftraining -U unicharset -O eng.unicharset eng.lucidaconsole.exp0.tr eng.lucidaconsole.exp1.tr and C:\Program Files (x86)\Tesseract-OCR>mftraining -U unicharset -O eng.unicharset eng.lucidaconsole.exp1.tr eng.lucidaconsole.exp0.tr On Aug 11, 12:01 pm, yem <[email protected]> wrote: > Dmitri > > Thanks for the response.
