Debugging in containers

Tired of "command not found" - these lines will install commonly used tools to debug networking, read logs, and other things.

Start a shell as root inside the container

CONTAINER_KEYWORD="spark"
CONTAINER_NAME=$(docker ps | grep -i "${CONTAINER_KEYWORD}" | head -n 1 | awk '{print $NF}')
echo "CONTAINER_NAME: ${CONTAINER_NAME}"

"""Benchmarks for the video reader: OpenCV vs Torchvision.

OpenCV is faster than Torchvision when just reading the frames, but it's slower when
    adding the conversions to RGB, tensor, float, and stacking the frames.

Results:
    Benchmarking OpenCV
            Read 300 frames in 0.84 seconds
            Read 300 frames in 0.81 seconds
            Read 300 frames in 0.98 seconds
