ValueError: Attempted relative import beyond toplevel package

[ifmaq1]

Hi, I am running a code on ubuntu server. I uploaded this project in my home directory and trying to generate captions on custom images using

$ bash scripts/dense_cap_demo.sh output/ckpt output/ckpt/vocabulary.txt

I created the data/demo and outputfile in this project's directory i-e

/home/densecap-tensorflow-master/data/demo

When I run bash scripts/dense_cap_demo.sh output/ckpt output/ckpt/vocabulary.txt

it gives me following error

+ set -e
+ ckpt=output/ckpt
+ vocab=output/ckpt/vocabulary.txt
+ '[' -d /home/joe ']'
+ python ./tools/demo.py --ckpt output/ckpt --cfg scripts/dense_cap_config.yml --vocab output/ckpt/vocabulary.txt --set TEST.USE_BEAM_SEARCH False EMBED_DIM 512 TEST.LN_FACTOR 1. TEST.RPN_NMS_THRESH 0.7 TEST.NMS 0.3

ValueError: Attempted relative import beyond toplevel package

how can i solve this issue. I cannot create directories in root folder as there are other users as well. I have access to my home directory only.
