[BUG]DeepSpeed ZeRO-2 Offload: backward does not populate IPG buckets even though autograd graph reaches parameters (PyTorch 2.0 / Python 3.8 / DeepSpeed 0.17.6)

When training with DeepSpeed ZeRO Stage 2 and optimizer offload to CPU, calling engine.backward(loss_) results in empty IPG buckets during gradient reduction (e.g., bucket.buffer: []). This leads to ...
