I saw these post but cannot
able to figure out the problem here. if you could just nudge me to my
actual problem it would be great.

i think I am getting this error because git lfs. I have dowloaded 0.4.1
git reposiratory by downloading zip on github. and did not cloned it
with git lfs. is this something I have to do. if yes how should I do it.
I never used gil lfs before

Unfortunately GitHub zip downloads don't work with LFS, you'll have to
install LFS and clone with git.
