Usage in macOS for Xamarin

Lingfeng158 commented 4 years ago

Hi takuya-takeuchi,

I'm new to .net platform, and I'm currently using Xamarin (from visual studio for Mac) to develop apps for iOS and Android. Since it is a .net package, I just assumed that it will also work in Xamarin. So here are my questions:

Can we build the project with CPU only? Is <cpu/cuda> choosing either cpu or cuda?
Can you please explain the parameters used in the build command Build.ps1 <Debug/Release> <cpu/cuda> 64 desktop <2015/2017/2019> <92/100/101> What does desktop <2015/2017/2019> <92/100/101> mean?

Thank you very much!

I'm very sorry. I didn't check osx build work for a long time.

Build.ps1 does not support Linux and OSX. You can use https://github.com/takuya-takeuchi/OpenPoseDotNet/blob/master/src/BuildMacOSX.sh.

$ ./BuildMacOSX.sh Release

And this script support only cpu. Because I have no osx machine with nvidia gpu.

I'm sorry that I pose multiple questions consecutively, but I'm a bit confused about the overall usage of your project, as I'm very new to .net and NuGet systems. Currently I hold a few questions about the project:

After build the project using src/BuildMacOSX.sh, I can find all the files in src/OpenPoseDotNet in Visual Studio. I would like to try out OpenPoseDemo, but I wasn't able to find any quick start guide for macOS. How should I use OpenPoseDemo under macOS?
Other tutorials start with executable or binary of OpenPose, but openposeDotNet it is a .NET Standard library, I assume that there is no executable for macOS? Then how should I use the library to make predictions?
What I would like to achieve is to input pictures of body and output coordinates of joints; input pictures of a face and output coordinates of the face. Could you please give me some suggestions/directions on using the library?

Thank you very much, and again, I'm deeply sorry for posting/editing/deleting my post repeatedly.

After run BuildOSX.sh, you find libopenpose.dylib but I can not current develop branch.
openposeDotNet is library, And you can use in your .NET core apps. You can build examples and run it by using openposeDotNet.dll and libopenpose.dylib. But due to 1., it is expectation.
These examples could satisfy your requirements.

@Lingfeng158 Latest develop branch support osx cpu binary.
