np.sum() Is supported on numsharp0.20.5, but not on NumSharp0.30.0

np.sum() Is supported on numsharp0.20.5, but not on NumSharp0.30.0 the exception message :"Specified method is not supported."

What datatype are you trying to use?

[lijianxin520]

double s = np.sum(w * w); w data type is NDArray;

[lijianxin520]

[Nucs]

I mean what will this output on NumSharp 20.5?

Console.WriteLine(w.dtype);
Console.WriteLine(s.dtype);

At version 30.x+ @Oceania2018 has removed many supported DTypes which might cause NotSupportedException or NotImplementedException. Some even return null.

Thank you very much for your attention, the following is the supplementary content.

same problem. Is there a walkaround for now?

[Nucs]

@lijianxin520 I was not able to reproduce this locally, can you or @bigdimboom provide with a simple unit test that reproduces this and I'll take a deeper look.

Hello, I encountered this problem as well and here's some data to help investigate:

1. A sample code which reproduces the problem on my Mac - Visual Studio. https://github.com/ppsdatta/NpSumIssue
2. With version 0.30.0 the code fails with the not supported error.
3. With version 0.20.5 the code works without runtime exception.

having exact same error, numsharp 0.30.0 any workaround besides you know... for?

[gv-collibris]

same error with NumSharp 0.30.0, with np.sum(NDArray[])

I also encountered the same error. When the value of elements of NDArray is double, this error certainly occur. To change the type double to float works well in my case.

same error here, sum() works for int but not for double, using version 0.30.0

I am using v4.0.30319 Numsharp. Getting the same error after calling the sum function. I am passing NDArray Double datatype.
