YOLOv8 export error: `ImportError: libssl.so.1.1: cannot open shared object file: No such file or directory`

[glenn-jocher]

YOLOv8 paddle export is failing with the latest version of 1.4.1 of x2paddle in Google Colab with:

• ultralytics 8.0.167
• paddlepaddle 2.5.1
• x2paddle 1.4.1

Reproduce

# Install
# pip install ultralytics paddlepaddle x2paddle

# Export
yolo export model=yolov8n.pt format=paddle

Result:

You can run this code in Google Colab here:

Even just importing x2paddle causes this error, so it appears to be unrelated to ultralytics

It seems the problem happend while import paddle framework. I will transfer this issue to github.com/PaddlePaddle/Paddle

looks like the same issue as here: https://github.com/PaddlePaddle/Paddle/issues/55597
