Hi,

We are getting the following error trying to build this packages on our Jetson:

Found the answer, git lfs needs to be installed, and then run git lfs pull to fetch the large files. This should really be added to the readme.

@hemalshahNV Can we add it into the readme or installation process? Got stuck with this too

[hemalshahNV]

We do mention git-lfs as a prerequisite because it is easy to forget but we can try to make this more explicit and see if we can add a warning.

@hemalshahNV I couldn't find git-lfs anywhere in the readme

We added to the Dev Env setup guide (here) to include running git lfs install which we run for you as part of the Docker image but if you don't, you'll need to run it yourself. Thanks for pointing this out!
