It means build pytorch from source code.

Hi, why should build pytorch from source code? Could you explain that? thanks.

[aelnouby]

The pytorch version you install using pip or conda is not the latest, it is the latest stable version they have published, sometimes they implement features on the repo but they are not yet added to the published version, in this case you need the build their source code from the master branch to get the latest features, second order gradients follows this case.

However, last week pytorch published a new version, so it might include the second order gradients. In this case you do not need to build from source, however I am not sure if it is included or not.

@aelnouby thanks for your detailed explaination, which is exactly what i want to known.
Which API involves the 2nd gradients you used, by the way?

Hi, Pytorch support higher order gradients from v0.2 already, please refer to : https://github.com/pytorch/pytorch/releases/tag/v0.2.0

Great ! at the time of this project development this feature was not available. I will edit the ReadMe. Thanks.
