Thanks for all the advices, I’m currently only displaying the difference but they are all zeros.
basic_net = alexnet(pretrained=True)
tb = SummaryWriter(comment = "Diff")
j = 0
for i in [0,3,6,8,10]:
  tb.add_histogram("Diff", basic_net.features[i].weight.data.cpu().numpy() - best_net_3_2_2.features[i].weight.data.cpu().numpy(), j)
  j = j+1
tb.close()

tb = SummaryWriter(comment = "Diffb")
j = 0
for i in [0,3,6,8,10]:
  tb.add_histogram("Diffb", basic_net.features[i].bias.data.cpu().numpy() - best_net_3_2_2.features[i].bias.data.cpu().numpy(), j)
  j = j+1
tb.close()
tb.flush()

Is that possible? Am I missing something?
