WebFor example, the Adam optimizer uses per-parameter exp_avg and exp_avg_sq states. As a result, the Adam optimizer’s memory consumption is at least twice the model size. Given this observation, we can reduce the optimizer memory footprint by sharding optimizer states across DDP processes. simplyhealth onlineWebApr 4, 2024 · # Instantiate optimizer opt = torch.optim.Adam (m.parameters (), lr=0.001) losses = training_loop (m, opt) plt.figure (figsize= (14, 7)) plt.plot (losses) print (m.weights) Losses over 1000 epochs — Image by Author..
