verbose=2 shows weights twice

[Matthijs Van keirsbilck]

Describe the bug

I want to see detail until layer.weight and layer.bias, and it seems this is only possible with verbose=2.
I tried setting max_depth=1000, but with verbose=1 the 'weight'/'bias' parameters are never shown in the summary.

With verbose=2, the weighs show up twice for some reason. Once at the top-level, and once under their actual layer (see below)

To Reproduce

import torch
import torch.nn as nn
from torchinfo import summary

model = nn.Sequential(
        nn.Linear(10,10),
        nn.Sequential(
            nn.Linear(10,10),
            nn.Linear(10,10)
        )
)

model_stats = summary(
    model,
    input_data=torch.randn(size=(1, 10)),
    verbose=2,
    col_names=["output_size", "kernel_size", "num_params", "mult_adds"], 
)

Output:
