Can or is the new ROS Gem Neural network packcage a substitute or alternative to this?

[FPSychotic]

i cannot use it in Foxy, and would be redundant if they do the same, but Im not sure

You can use this ros_deep_learning package in Foxy, here is how you can install it in your own container:

https://github.com/dusty-nv/jetbot_ros/blob/e2bd28b3e182d772ef051f1cc0e5c42c9fb4f1ec/Dockerfile#L123

Base it off of dustynv/ros:foxy-pytorch-l4t-r32.5.0 container (pick the appropriate tag for your respective version of JetPack-L4T)

But yes, the Isaac ROS package is an alternative to this one, which I collaborated with the Isaac ROS team on. So you are welcome to use whichever better suits your needs.
