Closed Ar57m closed 4 months ago

Ar57m commented 4 months ago

Problem description

recently I pkg update everything, and cv2 stopped working, somebody know how to fix it? I forgot to copy the logs of the update but I have a screenshot, Screenshot_20240526_214418_Termux

the error running the python script:

Traceback (most recent call last):
  File "/data/data/com.termux/files/home/another/runner.py", line 3, in <module>
    import cv2
  File "/data/data/com.termux/files/usr/lib/python3.11/site-packages/cv2/__init__.py", line 181, in <module>
    bootstrap()
  File "/data/data/com.termux/files/usr/lib/python3.11/site-packages/cv2/__init__.py", line 153, in bootstrap
    native_module = importlib.import_module("cv2")
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
ImportError: dlopen failed: cannot locate symbol "_ZN4absl12lts_2023080212log_internal9kCharNullE" referenced by "/data/data/com.termux/files/usr/lib/libopencv_dnn.so"...

What steps will reproduce the bug?

pkg update and upgrade run a python script importing cv2

What is the expected behavior?

import cv2

opencv has been removed from main to x11. Please install x11-repo.

apt install x11-repo && apt update && apt install opencv
