基于深度学习和TensorFlow的英文和汉字验证码识别

captcha-recognition's Issues

汉字识别

像这样验证码,需要在4组选项,每组4个汉字中,选择一组匹配的汉字.
应该经过哪些步骤的处理?

运行test文件正确率是0

模型还没训练完，在五万step左右，运行test后正确率是0，为什么啊，正常吗

请问下运行generate_tfrecord时出现这个错误怎么解决

训练多少步

请问楼主训练多少步

模型训练问题

请问下我的第二类第三类模型为啥训练了两三天还没训练完

生成pb模型

level2的例子中，我想用ckpt文件生成pb模型，但是需要指定输出名字。我是用ArgMax显示不存在。 使用FC2/wx_plus_b结果好像对不上。

请问一下运行denoise时出现这种错误怎么解决

请问识别出来的验证码结果是放在mapping里吗

test报错

The passed save_path is not a valid checkpoint: ./model/model_level3.ckpt-800
运行test.py报错
