Improved visualization tool of torchsummary. Here, it visualizes kernel size, output shape, # params, and Mult-Adds. Also the torchsummaryX can handle RNN, Recursive NN, or model with multiple inputs.
pip install torchsummaryX and
from torchsummaryX import summary
summary(your_model, torch.zeros((1, 3, 224, 224)))Args:
model(Module): Model to summarizex(Tensor): Input tensor of the model with [N, C, H, W] shape dtype and device have to match to the modelargs, kwargs: Other arguments used inmodel.forwardfunction
