libGL.so.1: cannot open shared object file: No such file or directory - even when using open cv headless

Question

I have a Docker image I am building to run on AWS Lambda.

One of the dependencies is opencv, but I am using the headless version.

My requirements file is:

absl-py==1.0.0
attrs==21.4.0
cycler==0.11.0
flatbuffers==2.0
fonttools==4.33.3
imageio==2.19.2
jmespath==1.0.0
kiwisolver==1.4.2
matplotlib==3.5.2
mediapipe==0.8.10
networkx==2.8.1
numpy==1.22.3
onnxruntime==1.11.1
opencv-contrib-python-headless==4.5.5.64
packaging==21.3
Pillow==9.1.1
protobuf==3.20.1
pyparsing==3.0.9
python-dateutil==2.8.2
PyWavelets==1.3.0
scikit-image==0.19.2
scipy==1.8.1
six==1.16.0
tifffile==2022.5.4
urllib3==1.26.9

And my Dockerfile is:

FROM public.ecr.aws/lambda/python:3.8

COPY requirements.txt .
RUN pip install -r requirements.txt && rm requirements.txt

COPY lambda_function.py ./
COPY remove.py ./
COPY detect.py ./
COPY u2net.onnx ./
CMD [ "lambda_function.lambda_handler" ]

The exact error I am getting in Lambda is:

{
  "errorMessage": "Unable to import module 'lambda_function': libGL.so.1: cannot open shared object file: No such file or directory",
  "errorType": "Runtime.ImportModuleError",
  "stackTrace": []
}

I have tried researching what could be happening but have come up empty handed. Why would I be getting this error when using the headless version? Thank you

probabily also the opencv contrib module should be headless: "opencv-contrib-python-headless" — Miki

@berak just to clarify, are you saying to get rid of opencv-python-headless and just have opencv-contrib-python-headless as the opencv install? — pycode81

@berak I have updated my question with the requirements I am using now. I have tried it with the new list and it is still giving me the same error. — pycode81

I needed to update my container repositories and install a dependency, libgl1-mesa-glx:

RUN apt update
# Dependency for opencv-python (cv2). `import cv2` raises ImportError: libGL.so.1: cannot open shared object file: No such file or directory
# Solution from https://askubuntu.com/a/1015744
RUN apt install -y libgl1-mesa-glx
