Here we're using greedy decoding so the performance may be lower. Is there any PyTorch implementation of beam decoder like in tf:

在模型转换一个tf上训练好的ocr crnn时，有不支持的算子，想问一下目前MNN支持RNN和CTC算子么

假设已经定位到文字部分（暂不考虑定位方法），若采用AttentionOCR去识别，识别结果是针对图片中文字整体识别还是针对图片中的文字一个一个进行识别，因为之前采用crnn-ctc的模型是对图片中的文字一起识别，但是我看到您的images文件夹中图片有标识每一个汉字的识别概率，不知道我表达清楚没有^~^

First, thanks for your nicely working captcha recognition repo. I would have a question regarding CRNN:
1) In the ctc_lambda_func you have that iy_pred = iy_pred[:, 2:, :], but I always thought the…

现在的新版本比以前的代码效果差很多， 希望把之前的代码加一个branch，谢谢。@Sierkinhane
