Segmentation fault while running python in docker container

I am trying to run this Github project on docker on my machine. Here is my docker file that I am running after cloning the project on my local machine.

FROM python:3

RUN mkdir -p /opt/cascade-server
WORKDIR /opt/cascade-server
COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .
COPY docker_defaults.yml conf/defaults.yml

CMD /bin/bash docker_start.sh

All my configurations are correct and working fine. When I run the project without docker containers, it runs correctly. When I build Docker containers to install it, it does not ends on python cascade.py -vv when running the below shell script from the last line of docker.

#!/bin/bash

if [ -f "conf/cascade.yml" ]; then
   echo "cascade.yml found. Using existing configuration."
else
   echo "cascade.yml not found. Generating new config file from defaults"
   python cascade.py --setup_with_defaults
fi

python cascade.py -vv

All the logs are showing correct results till the last line executes from the shell script. Here is the error when the last line executes.
