Segmentation fault in AWS Lambda call

[dioh]

When using python-opencv-headless for runtime python 3.8 will throw segmentation fault on invocation. Do you know why is this happening?

Dockerfile:

`FROM amazonlinux

WORKDIR /
RUN yum update -y

Install Python 3.8

RUN yum install gcc openssl-devel bzip2-devel libffi-devel wget tar gzip make -y
RUN wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz
RUN tar -xzvf Python-3.7.0.tgz
WORKDIR /Python-3.7.0
RUN ./configure --enable-optimizations
RUN make install

Install Python 3.7

RUN yum install python3 zip -y

Install Python packages

RUN mkdir /packages
RUN echo "opencv-python-headless" >> /packages/requirements.txt
RUN mkdir -p /packages/opencv-python-3.7/python/lib/python3.7/site-packages

RUN mkdir -p /packages/opencv-python-3.8/python/lib/python3.8/site-packages

RUN echo "numpy" >> /packages/requirements.txt
RUN echo "pdf2image" >> /packages/requirements.txt
RUN pip3.7 install pip --upgrade
RUN pip3.7 install -r /packages/requirements.txt -t /packages/opencv-python-3.7/python/lib/python3.7/site-packages

Create zip files for Lambda Layer deployment

WORKDIR /packages/opencv-python-3.7/
RUN zip -r9 /packages/cv2-python37.zip .
WORKDIR /packages/

RUN rm -rf /packages/opencv-python-3.7/

What's the exact error you're getting? You're just getting a seg fault?

Using this package on Serverless helped me streamline this whole process and reduce the package size as well. Would definitely recommend checking it out. Make sure to leave the strip flag to false
