The latest torchvision version (0.2.1) doesn’t seem to have the inplace parameter either on my machine:
In [1]: import torchvision

In [2]: torchvision.__version__
Out[2]: '0.2.1'

In [3]: torchvision.functional.normalize?
Object `torchvision.functional.normalize` not found.

In [4]: torchvision.transforms.functional.normalize?
Signature: torchvision.transforms.functional.normalize(tensor, mean, std)
Docstring:
Normalize a tensor image with mean and standard deviation.

See ``Normalize`` for more details.

Args:
    tensor (Tensor): Tensor image of size (C, H, W) to be normalized.
    mean (sequence): Sequence of means for each channel.
    std (sequence): Sequence of standard deviations for each channely.

Returns:
    Tensor: Normalized Tensor image.
File:      ~/miniconda3/lib/python3.6/site-packages/torchvision/transforms/functional.py
Type:      function



EDIT: I checked that for both the GPU and CPU versions on two separate machines.
