I agree, i costs me some time to find the problem caused by that.
The same here: https://stackoverflow.com/questions/48482787/pytorch-memory-model-torch-from-numpy-vs-torch-tensor 112


arr = np.arange(10, dtype=np.float32).reshape(5, 2)
t0  = torch.Tensor(arr)
t1  = torch.tensor(arr)
t2  = torch.from_numpy(arr)
arr

t1
t2
t2[:, 1] = 23.0

It’s confusing when your wife’s name is Katja, but you call her Tanja right? Unclear side effects are possible in both cases …
Searching for “torch tensor” can lead to different results containing torch.tensor and torch.Tensor results as well…
