from deepspeed.ops.zero_offload import FP16ZeROOffloadEngine

# Initialize the ZeRO-Offload engine
zero_offload_engine = FP16ZeROOffloadEngine()

# Wrap the model with the ZeRO-Offload engine
model, _, _, _ = zero_offload_engine.initialize(model=model, optimizer=optimizer)

# Train the model
for batch in data:
    loss = model(batch)
    loss.backward()
    optimizer.step()
    optimizer.zero_grad()
