Optimizer torch.optim.adam model.parameters

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
