https://github.com/KarimJedda/dahoam2017/blob/master/solver/captcha_model.py#L112

correct_prediction = tf.equal(tf.argmax(logits,2), tf.argmax(labels,2))

tf.equal is element-wise:

>>> a = [[1, 1, 1], [1,1,1]]
>>> b = [[1,0,0], [0,0,0]]
>>> tf.equal(a, b).eval()
array([[ True, False, False],
       [False, False, False]], dtype=bool)

The code is true unless the result of tf.equal(a, b).eval() is array([[False], [False]], dtype=bool), which is not the case.

Is there any publication (report or paper) that you have made for this? It would be helpful. Im doing research on this topic (Captcha and Deep Learning [Tensorflow]). If you have done any paper or report I will refer to your that paper or report berfore doing something on this topic.

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 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?

Hello,

The captcha_record.py seems to work perfectly fine.
However, how can I evaluate it ? I mean, if I launch captcha_eval.py after stopping captcha_record.py, I just get a lot 0 precision as my computer doesn't remember the training.
How are we supposed to use it ?

Thanks in advance for your help
