Ubuntu 18.04.6 LTS
Python 3.8.12
paddleocr 2.7.0.3
paddlepaddle 2.4.2

使用：enable_mkldnn=True，OCRV4 推理耗时变长，在该环境中OCRV3版本，有正向加速

[renoyuan]

遇到一样的问题，且识别模型的结果也都错误了

[jakclisky]

me too

[SeeYouAgainZm]

我也碰到类似的问题

[SeeYouAgainZm]

我是不开启mkldnn 10来秒，开启mkdnn，需要2分多钟的时间

[GreatV]

这个应该跟cpu指令集有关系，可以试试换其他cpu运行运行。

[SeeYouAgainZm]

好的，我试试

[DriftingSonny]

解决了吗，我换成v3的也很慢，模型和检测内容倒是没有错。原来1s一个，用了mkldnn要8s。我用别的大佬写的用fastdelopy的识别同一张图片能0.3s（同一台电脑）。
