-## 近期更新（2021.4.12）
-#### Q2.2.9: 端到端算法PGNet使用的是什么类型的数据集呢？
-**A**: PGNet目前可以使用四点标注数据集，也可以使用多点标注数据集（十四点），多点标注训练的效果要比四点的好，一种可以尝试的策略是先在四点数据集上训练，之后用多点数据集在此基础上继续训练。
+## 近期更新（2021.4.20）
 
-#### Q2.3.21:  端到端算法PGNet是否支持中文识别，速度会很慢嘛？
-**A**：目前开源的PGNet算法模型主要是用于检测英文数字，对于中文的识别需要自己训练，大家可以使用开源的端到端中文数据集，而对于复杂文本（弯曲文本）的识别，也可以自己构造一批数据集针对进行训练，对于推理速度，可以先将模型转换为inference再进行预测，速度应该会相当可观。
+#### Q3.1.58: 使用PGNet进行eval报错？
+**A**: 需要注意，我们目前在release/2.1更新了评测代码，目前支持A，B两种评测模式：
+* A模式：该模式主要为了方便用户使用，与训练集一样的标注文件就可以正常进行eval操作, 代码中默认是A模式。
+* B模式：该模式主要为了保证我们的评测代码可以和Total Text官方的评测方式对齐，该模式下直接加载官方提供的mat文件进行eval。
 
-#### Q3.1.57: 端到端算法PGNet提供了两种后处理方式，两者之间有什么区别呢？
-**A**: 两种后处理的区别主要在于速度的推理，config中PostProcess有fast/slow两种模式，slow模式的后处理速度慢，精度相对较高，fast模式的后处理速度快，精度也在可接受的范围之内。建议使用速度快的后处理方式。
+#### Q3.1.59: 使用预训练模型进行预测，对于特定字符识别识别效果较差，怎么解决？
+**A**: 由于我们所提供的识别模型是基于通用大规模数据集进行训练的，部分字符可能在训练集中包含较少，因此您可以构建特定场景的数据集，基于我们提供的预训练模型进行微调。建议用于微调的数据集中，每个字符出现的样本数量不低于300，但同时需要注意不同字符的数量均衡。具体可以参考：[微调](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.1/doc/doc_ch/recognition.md#2-%E5%90%AF%E5%8A%A8%E8%AE%AD%E7%BB%83)
 
-#### Q3.3.34: 表格识别中，如何提高单字的识别结果？
-**A**: 首先需要确认一下检测模型有没有有效的检测出单个字符，如果没有的话，需要在训练集当中添加相应的单字数据集。
+#### Q3.1.60: PGNet有中文预训练模型吗？
+**A**: 目前我们尚未提供针对中文的预训练模型，如有需要，可以尝试自己训练。具体需要修改的地方有：
+  1. [config文件中](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.1/configs/e2e/e2e_r50_vd_pg.yml#L23-L24)，字典文件路径及语种设置；
+  1. [网络结构中](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.1/ppocr/modeling/heads/e2e_pg_head.py#L181)，`out_channels`修改为字典中的字符数目+1（考虑到空格）；
+  1. [loss中](https://github.com/PaddlePaddle/PaddleOCR/blob/release/2.1/ppocr/losses/e2e_pg_loss.py#L93)，修改`37`为字典中的字符数目+1（考虑到空格）；
 
-#### Q3.4.41: PaddleOCR持tensorrt推理吗？
-**A**: 支持的，需要在编译的时候将CMakeLists.txt文件当中，将相关代码`option(WITH_TENSORRT "Compile demo with TensorRT."   OFF)`的OFF改成ON。关于服务器端部署的更多设置，可以参考[飞桨官网](https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/05_inference_deployment/inference/native_infer.html)
+#### Q3.1.61: 用于PGNet的训练集，文本框的标注有要求吗？
+**A**: PGNet支持多点标注，比如4点、8点、14点等。但需要注意的是，标注点尽可能分布均匀（相邻标注点间隔距离均匀一致），且label文件中的标注点需要从标注框的左上角开始，按标注点顺时针顺序依次编写，以上问题都可能对训练精度造成影响。
+我们提供的，基于Total Text数据集的PGNet预训练模型使用了14点标注方式。
+
+#### Q3.4.42: 在使用PaddleLite进行预测部署时，启动预测后卡死/手机死机？
+**A**: 请检查模型转换时所用PaddleLite的版本，和预测库的版本是否对齐。即PaddleLite版本为2.8，则预测库版本也要为2.8。

 #### Q1.1.10：PaddleOCR中，对于模型预测加速，CPU加速的途径有哪些？基于TenorRT加速GPU对输入有什么要求？
 
-**A**：（1）CPU可以使用mkldnn进行加速；对于python inference的话，可以把enable_mkldnn改为true，[参考代码](https://github.com/PaddlePaddle/PaddleOCR/blob/dygraph/tools/infer/utility.py#L84)，对于cpp inference的话，在配置文件里面配置use_mkldnn 1即可，[参考代码](https://github.com/PaddlePaddle/PaddleOCR/blob/dygraph/deploy/cpp_infer/tools/config.txt#L6)

 `transcription` 表示当前文本框的文字，**当其内容为“###”时，表示该文本框无效，在训练时会跳过。**
 如果您想在其他数据集上训练，可以按照上述形式构建标注文件。
 
+**注意：PGNet支持任意点的数据输入，如4点、8点等，但是需要保证均匀标注（上下对称，左右距离一致）。在Total-Text数据集上，我们使用了14点标注进行训练。**
+
 ### 启动训练
 
 PGNet训练分为两个步骤：step1: 在合成数据上训练，得到预训练模型，此时模型精度依然较低；step2: 加载预训练模型，在totaltext数据集上训练；为快速训练，我们直接提供了step1的预训练模型。

 ```
 The image annotation after **json.dumps()** encoding is a list containing multiple dictionaries.
 
-The `points` in the dictionary represent the coordinates (x, y) of the four points of the text box, arranged clockwise from the point at the upper left corner.
+The `points` in the dictionary represent the coordinates (x, y) of the fourteen points of the text box, arranged clockwise from the point at the upper left corner.
 
 `transcription` represents the text of the current text box. **When its content is "###" it means that the text box is invalid and will be skipped during training.**
 
 If you want to train PaddleOCR on other datasets, please build the annotation file according to the above format.
 
+*PGNet supports data input of any point, but it needs to ensure uniform labeling (upper and lower symmetry, left and right distance is consistent). In our experiment, the training effect of fourteen points tagging is better than that of four points tagging. We can try to do two-stage training on four points tagging and fourteen points tagging.*
