麻烦看看啊，我这个环境是刚刚搭的，然后直接用来测试你的
from davarocr.davar_common.apis import inference_model

[qiaoliang6]

ctypelib相关错误是由于没找到对应的so文件，davarocr会依赖一些有cpp编译得到的lib，例如DAVAR-Lab-OCR/davarocr/davar_det/datasets/pipelines/lib/east_data.so等。可以看一下环境中时候有这些文件。

它是由DAVAR-Lab-OCR/davarocr/setup.sh执行后自动编译得到的，不知道你安装时时候执行了DAVAR-Lab-OCR/setup.sh脚本。

@EYcab @qiaoliang6 Did you resolve this issue? I got the same error :/

@EYcab @qiaoliang6 Did you resolve this issue? I got the same error :/

Have you successfully run 'setup.sh' command, then there will be some '.so' files generated, such as '/davarocr/davar_det/core/post_processing/lib/east_postprocess.so', etc.

You can check whether there are ".so" files generated.

[qiaoliang6]

I have update the code to remove the global calling of post_east. It would not affect other algorithms.

@qiaoliang6,thank you for asking, I have solved that error by implementing setup.sh in davarocr which requires g++ pre-installation.
