IDK what the issue is. RTD build fails right after I push a new commit.

[purva-thakre]

SO that might be possibly related to this issue.

It's not clear why the build passes locally but fails with a ModuleNotFoundError on RTD. \

Another related discussion in RTD repo on why a submodule couldn't be imported. Why only LRE import issues though? Why not other submodules?

Edit: I think this is happening because the submodules do not have init files.

@natestemen I managed to get the import issues fixed by adding init files in the submodules.
I am not too sure about what's preferred though because this deviates from what's followed in the submodules for other techniques.

@natestemen this is ready to be merged.

nit: it's good practice for files to end with a new line (even those init files)
