How to use the torch.optim.Adam function in torch Snyk

WebApr 20, 2024 · There are some optimizers in pytorch, for example: Adam, SGD. It is easy to create an optimizer. For example: optimizer = torch.optim.Adam(model.parameters()) By this code, we created an Adam optimizer. What is optimizer.param_groups? We will use an example to introduce. For example: import torch import numpy as np Weboptimizer = torch.optim.Adam(model.parameters(), lr=1e-5) It will take longer to optimise. Using lr=1e-5 you need to train for 20,000+ iterations before you see the instability and the instability is less dramatic, values hover around $10^{ … phillip lyons countryside
