## FAQ
1. 预测报错got an unexpected keyword argument 'gradient_clip'
安装的paddle版本不对目前本项目仅支持paddle1.7近期会适配到1.8。
2. 转换attention识别模型时报错KeyError: 'predict'
基于Attention损失的识别模型推理还在调试中。对于中文文本识别建议优先选择基于CTC损失的识别模型实践中也发现基于Attention损失的效果不如基于CTC损失的识别模型。
3. 关于推理速度
图片中的文字较多时,预测时间会增,可以使用--rec_batch_num设置更小预测batch num默认值为30可以改为10或其他数值。
4. 服务部署与移动端部署
预计6月中下旬会先后发布基于Serving的服务部署方案和基于Paddle Lite的移动端部署方案欢迎持续关注。
5. 自研算法发布时间
自研算法SAST、SRN、End2End-PSL都将在6-7月陆续发布敬请期待。
