captcha_records.py not working?

[Gintasz]

Hey,

I wrote you on FB messenger the same, I'm trying to use your library, I set up virtualenv, installed dependencies, generated captchas, etc, didn't change any source, but when I launch $ python captcha_records.py, I get this crash:

Looking for images in './data/train_data'
>> Writing ./data/train.tfrecords
Traceback (most recent call last):
  File "captcha_records.py", line 123, in <module>
    tf.app.run(main=main, argv=[sys.argv[0]] + unparsed)
  File "/Users/gintas/Downloads/dahoam2017-master/dahoam/lib/python2.7/site-packages/tensorflow/python/platform/app.py", line 48, in run
    _sys.exit(main(_sys.argv[:1] + flags_passthrough))
  File "captcha_records.py", line 102, in main
    conver_to_tfrecords(training_data, TRAIN_FILE)
  File "captcha_records.py", line 62, in conver_to_tfrecords
    label_raw = label_to_one_hot(label).tostring()
  File "captcha_records.py", line 42, in label_to_one_hot
    index.append(CHAR_SETS.index(c))
ValueError: substring not found

you said it might be because captcha generator isn't generating ans.txt or something, but looking at the source code it this repository, it means that this source isn't finished? Would you be able to commit the changes you have?

me, too. encounter an error.

In case you haven't found out the solution for error below:

Looking for images in './data/train_data'
>> Writing ./data/train.tfrecords
Traceback (most recent call last):
  File "captcha_records.py", line 123, in <module>
    tf.app.run(main=main, argv=[sys.argv[0]] + unparsed)
  File "/Users/gintas/Downloads/dahoam2017-master/dahoam/lib/python2.7/site-packages/tensorflow/python/platform/app.py", line 48, in run
    _sys.exit(main(_sys.argv[:1] + flags_passthrough))
  File "captcha_records.py", line 102, in main
    conver_to_tfrecords(training_data, TRAIN_FILE)
  File "captcha_records.py", line 62, in conver_to_tfrecords
    label_raw = label_to_one_hot(label).tostring()
  File "captcha_records.py", line 42, in label_to_one_hot
    index.append(CHAR_SETS.index(c))
ValueError: substring not found

It simply because this line of code below (function create_data_list in captcha_records.py) try to use split the captcha file name using _ as separator:

label_name = os.path.basename(file_name).split('_')[0]

Simply change it to . solve the issue:

label_name = os.path.basename(file_name).split('.')[0]

As for the IOError, apparently your captcha images are not correctly generated as I don't faced such an error.
