It seems to me that np.linalg.norm and torch.norm have different outputs.
torch version: 1.0.0
import torch
import numpy as np

var_torch = torch.randn((3,333,333))
var_numpy = var_torch.detach().numpy()
print(torch.norm(var_torch))
>>> tensor(1884.0406)
print(np.linalg.norm(var_numpy))
>>> 577.75214

Is this expected?
