Where to download libpaddle_inference.so version 2.7 for ubuntu 20?

[richardgohth]

Have downloaded from
https://paddleinference.paddlepaddle.org.cn/master/user_guides/download_lib.html#linux

but is not able to link with my versio 2.7 cpp program.

Where to download libpaddle_inference.so version 2.7 from?
Thank you

PaddleOCR v2.7 is supposed to be compatible with Paddle Inference v2.6, which could be downloaded from this page :
https://www.paddlepaddle.org.cn/inference/v2.6/guides/install/download_lib.html

[richardgohth]

Thank you.
Downloaded 3 versions. all got errors.

/usr/bin/ld: warning: libpaddle2onnx.so.1.0.0rc2, needed by /imps/bin/cam1/libpaddle_inference.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libonnxruntime.so.1.11.1, needed by /imps/bin/cam1/libpaddle_inference.so, not found

[richardgohth]

managed to download libpaddle2onnx and libonnxruntime and compile
but now has run time errors

that is warning, and libonnxruntime.so.1.11.1 and libpaddle2onnx.so.1.0.0rc2 are not required.

[TingquanGao]

could you provide the total log of compiling and runing? that are useful to analyse and solve errors.

[richardgohth]

Hi Mr. Gao,
Thanks for your assistance. Appreciate it.
To reduce the program, we compiled ppocr and run it,
we found the same crash during running.
Our OS is Ubuntu 20.
ppocr.tgz

below debug trace
seems crashed at libc

update:
copied ppocr to ubuntu 18 system
and it was able run

[TingquanGao]

I am confirming the requirements of the Paddle Inference for OS. What os that ppocr be compiled on?

[richardgohth]

Ubuntu 20

@richardgohth Normally, Paddle library is compiled through Centos, so there will be no version issues. Based on your test, the library supports Ubuntu 18, and you can compile it in your environment through the link https://www.paddlepaddle.org.cn/inference/v2.6/guides/install/compile/source_compile_under_Linux.html Thx.

[richardgohth]

Thanks anyway.
