Sorry about the delay! I didn't see this PR :/

For some reason, the macos GH Actions builds didn't run on this PR (and there's no way for me to "unlock" them). Can you try updating your branch to see if it gives me an option to trigger builds?

Thanks for the PR!

What can I do to update it? I see that my branch is up to date.

[VivekPanyam]

You can run git commit --amend on your branch locally and then force push the commit (git push -f origin [your branch name]).

This effectively replaces your original commit with a new one containing the same changes (which should retrigger builds).

Also, just a heads up, I manually tested this change and it breaks mac CI (with some virtualenv errors). You may need to update the virtualenv version in

neuropod/build/install_python_deps.sh

${NEUROPOD_PYTHON_BINARY} -m pip install virtualenv==16.7.9
