Quick start

1. To set up the development environment and build TensorFlowSharp, please refer to the following.
2. Create a CNN model
3. Create a project with unity

How to make development environment

Clone( or Download) TensorFlowSharp

ubuntu 16.04

Install flatpak

Reference: Install MonoDevelop preview via FlatPak

$ sudo add-apt-repository ppa:alexlarsson/flatpak
$ sudo apt update
$ sudo apt install flatpak

Install mono Dev

$ flatpak install --user --from https://download.mono-project.com/repo/monodevelop.flatpakref

$ cd Downloads
$ wget https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-linux-x86_64-1.1.0.tar.gz
$ cd /usr/local
$ sudo tar xzvf ~/Downloads/libtensorflow-cpu-linux-x86_64-1.1.0.tar.gz
#Configuration a path
$ cd /etc/ld.so.conf.d
$ sudo vim lib_path.conf
#Save the string below(A directory with Libtensorflow.so)
/usr/local/lib
#Rebuild /etc/ld.so.cache
$ sudo ldconfig
$ ldconfig -p > ~/out.txt
#Check if the library has been added
$ find ~/ -type f -name "out.txt" | xargs grep 'libtensorflow.so'

Build the solution

Open the solution (.sin) right under the clone (or download) directory with MonoDevelop.
Next, rebuild the solution with Build -> Rebuild All.
I move SampleTest. Select SampleTest and press Build Project.

Start the executable file on the console.

Install mono-complete

$ sudo apt-get install mono-complete
$ cd ~/workspace/c_sharp/TensorFlowSharp/SampleTest/bin/Debug
$ mono SampleTest.exe

[Additional notes]
Reference:Nuget and “Unable to load the service index”

I got an error as below. (on 7.29 2017)

[nuget.org] Unable to load the service index for source https://api.nuget.org/v3/index.json. An error occurred while sending the request
Error: SecureChannelFailure (Object reference not set an instance of an object) Object reference not set to an instance of an object

How to deal
run command below from terminal.

export MONO_TLS_PROVIDER=legacy

So the build will pass.
