\n The method should build up the condition on the conditionGraph and the body of the while \n loop in the provided bodyGraph. It should set the condOutput to the value used as the\n condition output and the array of values in bodyOutputs to the final outputs as well as the\n name to be used, if not set, one will be assigned.\n

\n

\n The conditionGraph represents the while condition and the inputs are the current values of the\n input variables (condInputs). The output should be a scalar boolean.\n

\n

\n The loop body graph is in bodyGraph, The inputs are the current values of the loop\n variables. The outputs are the updated values of the loop variables.\n

Run the ExampleObjectDetection util from command line: 12 | ``` 13 | ExampleObjectDetection 14 | ``` 15 | 16 | By default, the example downloads a pretrained model, but you can specify your own using the following options: 17 | 18 | _input_image_ - optional, the path to the image for processing (the default is 'test_images/input.jpg') 19 | _output_image_ - optional, the path where the image with detected objects will be saved (the default is 'test_images/output.jpg') 20 | _catalog_ - optional, the path to the '*.pbtxt' file (by default, 'mscoco_label_map.pbtxt' been loaded) 21 | _model_ - optional, the path to the '*.pb' file (by default, 'frozen_inference_graph.pb' model been used, but you can download any other from here https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md or train your own): 22 | ``` 23 | ExampleObjectDetection --input_image="/demo/input.jpg"

-------------------------------------------------------------------------------- /CONTRIBUTING.md: -------------------------------------------------------------------------------- 1 | TensorFlowSharp are bindings to the native TensorFlow library. 2 | 3 | You can either use the TensorFlow C-library release binaries, or build 4 | your own from source. Here are some pre-built TensorFlow binaries you 5 | can use for each platform: 6 | 7 | - Linux 8 | - CPU-only: https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-linux-x86_64-1.1.0.tar.gz 9 | - GPU-enabled: https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-gpu-linux-x86_64-1.1.0.tar.gz 10 | - Mac: https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-darwin-x86_64-1.1.0.tar.gz 11 | - Windows: https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.2.0-rc0.zip 12 | 13 | Unpack the above .tar.gz suitable for your system on a prefix that your 14 | system's dynamic linker can use, for example, go to `/usr/local` and unpack there. 15 | 16 | Mac note: the package contains a `.so` file, you will need to rename this to `.dylib` for 17 | it to work. 18 | 19 | Once you do that, you need to open the solution file on the top 20 | level directory and build. This will produce both the TensorFlowSharp 21 | library as well as compile the tests and samples. 22 | 23 | ## Building your own native TensorFlow library 24 | 25 | You will wan to use Visual Studio 2017 or Visual Studio for Mac to build. 26 | 27 | To build the TensorFlow C library from source, 28 | [follow these instructions](https://github.com/tensorflow/tensorflow/blob/master/tensorflow/go/README.md#building-the-tensorflow-c-library-from-source). 29 | 30 | This includes checking out the Tensorflow sources, installing Bazel, 31 | and building the core. 32 | 33 | Once you do that, you will need to build the shared library. 34 | First, in the tensorflow directory, run: 35 | 36 | ```bash 37 | ./configure 38 | ``` 39 | 40 | and answer the various prompts about your build. Important: 41 | building with CUDA support provides better runtime performance 42 | but has additional dependencies as discussed in the Tensorflow 43 | installation Web page. 44 | 45 | Once configured, run: 46 | 47 | ```bash 48 | bazel build -c opt //tensorflow:libtensorflow.so 49 | ``` 50 | 51 | If you want debug symbols for Tensorflow, while debugging the binding: 52 | 53 | ```bash 54 | bazel build -c dbg --strip=never //tensorflow:libtensorflow.so 55 | ``` 56 | 57 | You will need the generated library (`libtensorflow.so`) to be installed in a 58 | system accessible location like `/usr/local/lib` 59 | 60 | On Linux: 61 | 62 | ```bash 63 | sudo cp bazel-bin/tensorflow/libtensorflow.so /usr/local/lib/ 64 | ``` 65 | 66 | On MacOS: 67 | 68 | ```bash 69 | sudo cp bazel-bin/tensorflow/libtensorflow.so /usr/local/lib/libtensorflow.dylib 70 | ``` 71 | 72 | ## Running the test 73 | 74 | I am currently using Visual Studio for Mac to do the development, but this 75 | should work on Windows with VS and Linux with MonoDevelop. 76 | 77 | Before the solution will run you will need the shared library generated to 78 | be on a location accessibly by the Mono runtime (for example /usr/local/lib). 79 | 80 | While Tensorflow builds a library with the extension .so, you will need 81 | to make sure that it has the proper name for your platform (tensorflow.dll on Windows, 82 | tensorflow.dylib on Mac) and copy that there. 83 | 84 | Tensorflow is a 64-bit library, so you will need to use a 64-bit Mono to run, 85 | at home (where I am doing this work), I have a copy of 64-bit Mono on /mono, 86 | so you will want to set that in your project configuration, to do this: 87 | 88 | Ensure that your Build/Compiler settings set "Platform Target" to "x64". 89 | 90 | Open the solution file in the top directory, and when you hit run, this will 91 | run the API test. 92 | -------------------------------------------------------------------------------- /TensorFlowSharp/TensorFlowSharp.csproj: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | net471;netstandard2.0 5 | TensorFlowSharp 6 | TensorFlowSharp 7 | true 8 | full 9 | bin\Debug\TensorFlowSharp.xml 10 | true 11 | 0.1 12 | 1.15.0 13 | 14 | 15 | 16 | true 17 | TensorFlowSharp 18 | 1.15.3 19 | Miguel de Icaza 20 | https://github.com/migueldeicaza/TensorFlowSharp/blob/master/LICENSE 21 | https://github.com/migueldeicaza/TensorFlowSharp/ 22 | machine-learning, tensorflow, xamarin, c#, f# 23 | .NET Bindings for TensorFlow 24 | Miguel de Icaza 25 | .NET API for TensorFlow, Google's Machine Intelligence framework 26 | 1.15.3: Fixed libtensorflow.dll not being copied to output directory on .NET Core; 1.15.1: Add a Runner.Run method that does not allocate - contribution from Enrico Minack; 1.15.0: Updated to TensorFlow 1.15; 1.13.1: Fixes boolean and ushort tensor construction fixes from Enrico Minack; Runner.AddInput fixes from Colin Versteeg; captainst provided a convenience function for the samples; Zeeshan Ahmed added AdamOptimizer; Kevin Malenfant fixes a few bugs; Enrico Minack added support for mutable tensors; 1.13.0: An optimization implementation now exists for C#, contributed by Zeeshan Ahmed from the Microsoft data science team (RMSProp, SGD optimizer bindings); TFSession now has a static method for loading models; New methods for loading strings into tensors (also Zeeshan) 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | 35 | 36 | 37 | 38 | 39 | 40 | 41 | 42 | 43 | 44 | 45 | 46 | 47 | -------------------------------------------------------------------------------- /ecmadocs/en/TensorFlow/Adagrad.xml: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | TensorFlowSharp 6 | 1.0.0.0 7 | 8 | 9 | TensorFlow.AdaptiveOptimizer 10 | 11 | 12 | 13 | 14 | Adaptive stochastic gradient descent optimizer. 15 | 16 | To be added. 17 | 18 | 19 | 20 | 21 | 22 | Constructor 23 | 24 | 1.0.0.0 25 | 26 | 27 | 28 | 29 | 30 | 31 | 32 | 33 | 34 | The graph object. 35 | The learning rate for the SGD update. 36 | Learning rate decay over each update. 37 | A floating point value.
