机器为jetson arrch 64系统，jetpack 4.4.
根据官方编译好的whl文件（[Jetpack4.5(4.4): [nv_jetson-cuda10.2-trt7-xavier](https://paddleinference.paddlepaddle.org.cn/master/user_guides/download_lib.html#python)）,安装好PaddlePaddle, 调用没问题，
然后使用pip install paddleocr（不知道其他安装方式）,最终import 出错

如果不安装paddleocr, 通过git clone https://github.com/PaddlePaddle/PaddleOCR 然后pip install -r requirements.txt 运行tools/infer项目下predict_system.py文件，仍然出现相同问题。

请问我应该怎样才能调用该项目呢？例如怎样才能正常调用predict_system.py

推荐python3.7，3.6后续不再维护，另外要先安装paddle再安装paddleocr

Hi 这个问题你解决了吗？

[BenjiaminLiu]

解决了，先自己安装paddlepaddle， 不用安装paddleocr，自己根据代码调用可以跑通
