复现代码 / Reproduction Code

I have an issue when using PaddleOCR with Google Colab while choosing CPU runtime. The issue is only restricted to CPU runtime. If I go for GPU option everything works fine. I used the following code to install PaddleOCR into the Google Colab:

!pip install paddlepaddle
!pip install paddleocr

Then, I execture:

from paddleocr import PaddleOCR,draw_ocr
ocr = PaddleOCR(use_angle_cls=True, use_gpu=False)

The notebook crashes on the second line (on initializing PaddleOCR). I see the following line displayed on output:

Thank you.

you may try paddlepaddle 2.5

[knowpwr]

Thanks for the reply. Tried with paddlepaddle 2.5 and I got this error:

Error: Can not import paddle core while this file exists: /usr/local/lib/python3.10/dist-packages/paddle/fluid/libpaddle.so

at the following line:

from paddleocr import PaddleOCR,draw_ocr

Also, got another error:

ImportError: libssl.so.1.1: cannot open shared object file: No such file or directory

at:

from . import libpaddle
