Would this work as a starter code:
nb_samples = 1930
in_features = 240
hidden = 50
out_dim = 10

model = nn.Sequential(
    nn.Linear(in_features, hidden),
    nn.ReLU(),
    nn.Linear(hidden, hidden),
    nn.ReLU(),
    nn.Linear(hidden, out_dim)
)

x = torch.randn(nb_samples, in_features)
output = model(x)
