3. 可视化模型:在配置好SummaryWriter之后,可以使用以下代码来将模型输出到TensorBoard: writer.add_graph(model, input_to_model) 其中,model参数指定模型,input_to_model参数指定输入模型的数据。 4. 可视化损失函数:可以使用以下代码将损失函数输出到TensorBoard: writer.add_scalar('Loss/train', loss_train, epoch...

In the future, we will include a TextAndImageModelFuser to make this process more straightforward. Still, is not really complicated and it is a good example of how to use custom components in pytorch-widedeep.Note that the only requirement for the custom component is that it has a property...
Official Repository includes links to pretrained model checkpoints.Cross ViTThis paper proposes to have two vision transformers processing the image at different scales, cross attending to one every so often. They show improvements on top of the base vision transformer....
