Multinode Cleanup

[rcano-baseten]

🚀 What

• omits node count by default (for truss init) - we do this to try to limit the complexity of truss init. Users shouldn't have to worry about the parameter
• adds some validation, fixes some dict marshalling

💻 How

🔬 Testing

[squidarth]

I don't think we have to do this logic in from_dict right? I think we can just do:

        node_count = d.get("node_count")
        if node_count is not None:
            validate_node_count(node_count)
        return Resources(cpu=cpu, memory=memory, use_gpu=use_gpu, accelerator=accelerator, node_count=node_count)

If node_count is None, it'll be None anyway
