Hi, 

When you are using -c param, you need to provide gt.txt file names. The error in second case says that it didn't find and gt files from where it can build codec for your case. There are two things you can do:

1. If you know all the alphabets in your data, then simply create a gt.txt file and give it as -c 'abc.gt.txt', or

2. you can read all alphabets from your gt files as -c '*.gt.txt'. 

Hope that it will work :). 

Regards, 

Adnan

 How to use ocropus-rtrain

Hi folks,
 
I'm starting using ocropus this week, and I would like to train it to
understand a pattern..
 
I have the images and the *.gt.txt files with the expected result.
 
I run exactly as manual said, but, i can see the param -s no longer exists,
so I tried in many different ways and could succeed.

Have a look some examples i've been trying..
 
ocropus-rtrain P1.jpg -o result.txt
 
# inputs 1
 
# tests None
 
import ocrolib.lineest
 
# CenterNormalizer
 
# using default codec
 
# charset size 157 Traceback (most recent call last):
 
File "/usr/local/bin/ocropus-rtrain", line 121, in <module>
 
print "["+"".join(charset)+"]"
 
UnicodeEncodeError: 'ascii' codec can't encode characters in position
96-155: ordinal not in range(128)
 
 
When i use the -c 'UTF-8', i get the result:
 
# inputs 1
 
# tests None
 
import ocrolib.lineest
 
# CenterNormalizer
 
# building codec
 
Traceback (most recent call last):
 
File "/usr/local/bin/ocropus-rtrain", line 106, in <module>
 
for fname in ocrolib.glob_all(args.codec):
 
File "/usr/local/lib/python2.7/dist-packages/ocrolib/toplevel.py", line
215, in argument_checks
 
result = f(*args,**kw)
 
File "/usr/local/lib/python2.7/dist-packages/ocrolib/common.py", line
626, in glob_all
 
raise Exception("%s: expansion did not yield any files"%arg)
 
Exception: U: expansion did not yield any files
 
 
Any help?
 
 
All the best.
