import torch from torch.utils.tensorboard import SummaryWriter # Create a SummaryWriter instance with a log directory writer = SummaryWriter(log_dir='logs') # Create an example figure to add to the summary fig = torch.randn(3, 3) # Write the figure to the summary writer.add_figure('Example Figure', fig) # Close the SummaryWriter writer.close()This code creates a SummaryWriter instance with a log directory, generates an example figure using the torch.randn function, adds the figure to the summary using the add_figure method, and then closes the SummaryWriter. The add_figure method takes two arguments: a tag to label the figure, and the figure itself. The figure can be any matplotlib figure, or any other object that has a savefig method. Overall, this function is a part of the torch.utils.tensorboard package library.
