using OCRopus3

[hounaida Moalla]

Hello everyone

I used ocropus (in its original version), then ocropy (improved version), now I would like to use ocropus3 (in its new version). I wanted to start learning on my database with the following command:

ocroline-train -d myDataBase.gz -t myDataBase.gz -T 100 -o testmodel --epochs 1

but I got the following error:

/usr/local/lib/python2.7/dist-packages/matplotlib/__init__.py:962: UserWarning: Duplicate key in file "/home/ubuntu/.config/matplotlib/matplotlibrc", line # 2
  (fname, cnt))

    raise ValueError ("missing keys, got {}, want {}". format (sample.keys (), kw)
ValueError: missing keys, got ['__source__', 'txt', '__key__', 'index'], want {'image': 'png', 'transcript': 'txt'}

knowing that my database respects the file format of the uw3 database used by the author of ocropus.

can someone help me please?

thank you
