Unable to use corrcoef (using v1.0.7)

Issue #438 | Created by @Nexus452 | 2022-09-19 17:28:21 UTC |

Hi,

Looking at the doc : https://diffsharp.github.io/reference/diffsharp-tensor.html#corrcoef, the function should be available out of the box, however for some reason it is unavailable (intellisense + compile error).
In the doc, this function is between convTranspose3d and cos. Both functions are available to me (intellisense )
I have decompiled DiffSharp.Core and searched for corrcoef but I really can't find it.

Any idea what I should do to be able to use corrcoef ?

Thanks,
S

While it is in the docs, the library version with corrcoef is not yet released on nuget. The nuget version is from just before the PR adding corrcoef was merged in.

If you build a local version of DiffSharp and reference it directly, like below (changing the #I path), it will be there:

#I @"C:\Users\nexus452\Documents\GitHub\DiffSharp\bundles\DiffSharp-cpu\bin\Debug\net6.0"
#r "DiffSharp.Core.dll"
#r "DiffSharp.Data.dll"
#r "DiffSharp.Backends.Torch.dll"
#r "nuget: TorchSharp-cuda-windows, 0.96.0"


open DiffSharp
open DiffSharp.Compose
open DiffSharp.Model

open DiffSharp

let loss (x: Tensor, y: Tensor) = 
    let xy = dsharp.stack [|x; y|]
    xy.corrcoef().sum()
