mftraining produces "Missing font_properties"

[Eyal]

Hi,

I tried to train some letters & when I ran the mftraining with the parameters:

mftraining -U unicharset -O lang.unicharset font1.tr I recieved an error message: "Missing font_properties".

I'm working on windows 7, visual studio 2010.

When I used the already compiled mftraining.exe for windows I do NOT getting this error & I'm getting decent results from the trained file.

Just to be sure the text I have is not problematic, I did the same test on eurotext.tif and I'm still getting the error.

Any clue?

Thank you!

Yes I have a clue: you did not read documentation [1] neither you did not "google" for solution ;-)

Quite a good guess, but I'm very disappointed to to say - I DID read the documentation...

And I even run the following command:

mftraining -F font_properties -U unicharset font1.tr

And I got results which don't show any error... :

Reading font1.tr ...

Writing Merged Microfeat ...Done!

The font_properties file contains one line as follows:

font1 0 0 0 0 0

And then I run the command:

mftraining -U unicharset -O lang1.unicharset font1.tr

And I'm getting the following results:

Reading font1.tr ...

font1 has no defined properties.

!"Missing font_properties entry is a fatal error!":Error:Assert failed:in file ..\training\mftraining.cpp, line 287

Another guess?

[zdenko podobny]

Why you did not run 'mftraining -F font_properties -U unicharset -O lang1.unicharset font1.tr' ??? 

There is written that font_properties is required for 3.01 (e.g. you do not need to use '-F font_properties' for 3.00, but you need to use it for 3.01. 

BTW: 'mftraining --help' will show other options for mftraining

WOW!!!

It worked.

If you'll look again at the training manual, you'll see that there wasn't a combination of both -F & -O and that's why I didn't write such command.

I start to think - It seems sometimes there's a need to understand the instuctions and not just run them like a robot...

Thank you very much!!!

[78yrsold]

congratulations! it would be nice to give full commandline used by
you for
benefit of users of the forum.

[Eyal]

The only difference is the line I changed, but I'll send the whole batch I wrote:

tesseract.exe font1.tif font1 nobatch box.train

unicharset_extractor font1.box

mftraining -F font_properties -U unicharset  -O lang1.unicharset font1.tr 

cntraining font1.tr

copy normproto lang1.normproto

copy inttemp lang1.inttemp

copy pffmtable lang1.pffmtable

copy Microfeat lang1.Microfeat 

combine_tessdata lang1.

Good luck to all of you.

[Sriranga(78yrsold)]

Eval,
Thank you very much for your prompt reply. I find it very useful for the users.
Awaiting your whole batch you wrote. Keep it up good work.
Wish you Good Luck and Success in your good mission,

Dear Eval,
 small modification =
instead of "copy normproto lang1.normproto" why not use as
"rename normproto lang1.normproto" etc.
With Best Wishes,

Sriranga,

I wrote "rename" in my first version of the batch but when I already had a file with the same name, the rename command failed.

Anything else?

Eyal.

[Sriranga(78yrsold)]

Eval,
I tested with "rename" it works for me. Only what i have done is replaced "copy"
in the commandline with " rename" nothing else. extract of cmd is reproduced below for ready reference.

J:\New000-r527>dir no*.*

 Volume Serial Number is D067-55AF

2)Better to create single  .bat file for all the commandlines you wrote.
I am not well versed with creation of .bat files -which automate all functions of commandlines.

Just copy all the lines in one file - call it train.bat & double click it.

The importance of the "copy" is when you'll have allready a file with that name.

Try to create a file named: heb.inttemp and put in it some text.

you'll see that the training will fail.

Good luck,

Eyal

[Sriranga(78yrsold)]

Eval,
Thanks for the valuable guidance.
Yes. If " copy" is used  the conttents of the existing file will be replaced.
With Best of GOOD LUCK,
-sriranga(78yrs)

I will try to improve wiki pages (e.g. AddOns) in next days. If you or others have some project (that use tesseract) or if you have found some bugs/mistake on wiki - just let me know ;-)

I think "MOVE /Y" should work better than COPY or RENAME in
that case.

Hi Delli,

You need to make a little file called font_properties, as explained
in the training guide here:
http://code.google.com/p/tesseract-ocr/wiki/TrainingTesseract3#font_properties_(new_in_3.01)

Hi Zdenko,

 

Here am sending the unicharset file and font_properties file and also please tell me how to create unicharambigs i follwed training process but i dint get it

 

sorry for late reply.

 

Thanks,

Delli

[bottu dilli babu]

[zdenko podobny]

unicharset file you sent in not correct output from unicharset_extractor for eng.fontfile.exp0.box. How did you created it?

font_properties do not follow wiki[1].

your eng.fontfile.exp0.tif do now follow wiki[2] ("It is ABSOLUTELY VITAL...")

[Francisco Loché Costa]

Did you call the shapeclustering instruction after mftraining? And the unicharset extractor?

If not, these are the instructions:

>unicharset_extractor [font].[name].exp0.box
>shapeclustering -F font_properties -U unicharset [font].[name].exp0.tr

Works for me on tesseract 3.02.
