Question

I m interested in seeing neural network as graph using tensorboard. I have constructed a network in pytorch with following code-

import torch
BATCH_SIZE = 16
DIM_IN = 1000
HIDDEN_SIZE = 100
DIM_OUT = 10

class TinyModel(torch.nn.Module):

    def __init__(self):
        super(TinyModel, self).__init__()

        self.layer1 = torch.nn.Linear(DIM_IN, HIDDEN_SIZE)
        self.relu = torch.nn.ReLU()
        self.layer2 = torch.nn.Linear(HIDDEN_SIZE, DIM_OUT)

    def forward(self, x):
        x = self.layer1(x)
        x = self.relu(x)
        x = self.layer2(x)
        return x

some_input = torch.randn(BATCH_SIZE, DIM_IN, requires_grad=False)
ideal_output = torch.randn(BATCH_SIZE, DIM_OUT, requires_grad=False)

model = TinyModel()

Setting-up tensorboard

from torch.utils.tensorboard import SummaryWriter

# Create a SummaryWriter
writer = SummaryWriter("checkpoint")

# Add the graph to TensorBoard
writer.add_graph(model, some_input)
writer.close()

While I run tensorboard --logdir=checkpoint on terminal , I receive the following error -

Probably the issue will be fixed in future releases, but is there a fix for now?

Answer 1

Your code seems to be written in numpy < 2.0 compatible way, but it seems like you are running it with numpy >=2. Try downgrading the numpy version to < 2.0.
