可能解决方案 / Possible solutions

I manually edit the paddle.py file, on code from :

from tools.infer import predict_system
from tools.infer.utility import draw_ocr, str2bool, check_gpu

to :

from paddleocr.tools.infer import predict_system
from paddleocr.tools.infer.utility import draw_ocr, str2bool, check_gpu

are this is expected?

[GreatV]

You're right, tools is the generic name, it's better to import it with the namespace paddleocr.

[yogi0421]

@GreatV did you know the release branch that solved this issue? or this issue are still happen on almost all version of paddleocr?

[GreatV]

@yogi0421 This issue is not yet fixed in the release branch.

I encountered the same issue, which only occurred in version 2.8.0; there were no problems in version 2.7.3. To resolve it, I replaced tools.infer with paddleocr.tools.infer which fixed the problem.

[myhloli]

@GreatV I carefully reviewed the differences between versions 2.7.3 and 2.8.0, and found that in 2.8.0, "from tools.infer import predict_system" was placed before the definition of the "tools" methods. This is why the issue did not reproduce on 2.7.3. I have already submitted the fix code at https://github.com/PaddlePaddle/PaddleOCR/pull/13348
