Developing issues
I just have some questions about developing on TorchSharp:
- I use Visual Studio 2022, but it doesn't give me IntelliSens support in the TorchSharp library. I'm not sure why, or how to resolve that.
- I can run the tests using
dotnet test, but that runs all the tests, while it would be nice to just run the new tests I create. Is there some configuration I am missing to make the tests appear in the test explorer, for example?
That is odd. I also use VS 2022, and I'm seeing both Intellisense and the unit tests appear in the test explorer. You sometimes need to do a 'run all' in the text explorer in order for the tests to appear, I have found.
I managed to get the above working, but now when I want to run tests, I get the following error: Severity Code Description Project File Line Suppression State Details Error CS0006 Metadata file 'C:...\TorchSharp\bin\AnyCPU.Debug\TorchSharp\netstandard2.0\TorchSharp.dll' could not be found TorchAudio (net6.0) C:...\TorchSharp\src\TorchAudio\CSC 1 Active There's in total 7 such errors (each at a slightly different path for the different projects and builds)
Any ideas?
What packages are you using? Start with TorchSharp-cpu. What version of .NET are you using?
Not sure what you mean with packages. How can I ensure only TorchSharp-cpu is being built?
As for the version of .NET:
dotnet --list-sdks

I do find that when I try to build the TorchSharp project separately, it complains about cmake not existing:

However, I have the C++ CMake tools for Windows installed. Adding C:\Program Files\Microsoft Visual Studio\2022\Community\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin to my PATH also didn't help.
I'm sorry. I completely missed that you were doing from-source builds. Have you checked out the DEVGUIDE.md file?
When building, always run from a VS 'x64 Native Tools...' window -- that sets up the right environment. Start VS from that window, with devenv TorchSharp.sln. Here's what I see:

@NiklasGustafsson I am very sure this answer needs a more prominent way to be available to new users.
Haven't seen anything on this for a while. I'm going to assume the question has been addressed.
