Question

i am trying to run cv2, and when i try to import it i get

ImportError: libGL.so.1: cannot open shared object file: No such file or directory

the suggested solution online is installing

apt install libgl1-mesa-glx

but this is already installed and the latest version.Any help would be really helpful.Thanks in advance.

Answer 1

RUN apt-get update ##[edited]
RUN apt-get install ffmpeg libsm6 libxext6  -y

Add these lines to your Dockerfile

Answer 2

This is a little bit better solution in my opinion. Package python3-opencv includes all system dependencies of OpenCV.

RUN apt-get update && apt-get install -y python3-opencv
RUN pip install opencv-python

Answer 3

Put this in the Dockerfile

RUN apt-get update
RUN apt install -y libgl1-mesa-glx

Before the line

COPY requirements.txt requirements.txt

For example

......

RUN apt-get update
RUN apt install -y libgl1-mesa-glx

COPY requirements.txt requirements.txt

......

Answer 4

Please run the following commands

sudo apt update


sudo apt install libgl1-mesa-glx

had the same issue on centos 8 after using pip3 install opencv on a non gui server which is lacking all sorts of graphics libraries.

dnf install opencv

pulls in all needed dependencies.
