Is there interest to make TorchSharp for user friendly with e.g. .NET Interactive?

Torch.SetSeed(1234);
var tensor = Float32Tensor.rand(new long[] { 4, 4 });
Console.Write(tensor)

Currently, there is no friendly print function when using TorchSharp in e.g. .NET Interactive , or I could have miss it?

I’m proposing a second ToString() overload defined on TorchTensor:

public string ToString(bool withData, string fltFormat = "g5", int width = 100)

The boolean is there to distinguish from the overriden ToString(), and is not necessary if the method is called something else.

One could also define it as:

public new string ToString(bool withData = false, string fltFormat = "g5", int width = 100)

to hide the overridden method.

Anyway, it would produce output like this:

[2x2x4], type = Float32, device = cpu

[0,:,:] =
 0.0000000   3.1410000 6.2834000    3.1415200
 0.0000063 -13.1415300 0.0100000 4713.1400000

[1,:,:] =
 0.0100000 0.0000000 0.0000000 0.0000000
 0.0000000 0.0000000 0.0000000 0.0000000

In this case, by passing in “0.0000000” as the format string.

The width parameter is there to prevent the method from making up extremely long lines. Instead, when the width is reached, each row ends with ‘…’

Working on a better ToString() would be interesting. I’m personally partial to how Julia prints tensors with more than two dimensions:

julia> x = rand(5,5, 5,5)
5×5×5×5 Array{Float64, 4}:

I like that the indices are printed (Julia is a column-major language, so the indices would be in the first dimensions rather than the last in .NET.)

@dsyme – you probably have thoughts on this topic.
