I am looking to adapt TensorFlow and its ANN capabilities for my computational mechanics purposes where majority of my codes are in c++. Is it possible to compile in c++ without using Bazel while including TensorFlow .h files? If so, I would really appreciate an example (haven't be able to find any online so far). Thanks
Edit: I did but i am not able to follow. Let me provide an example and maybe we can go from there. I am using ubuntu 16.10, gcc (Ubuntu 6.2.0-5ubuntu12) 6.2.0 20161005, and Python 2.7.12+. I have installed bazel from source and also have cloned TF repository (~/Desktop/tensorflow). Taking a slightly modified example from (https://www.tensorflow.org/api_guides/cc/guide), i have in example.cc:
#include "tensorflow/cc/client/client_session.h"
#include "tensorflow/cc/ops/standard_ops.h"
#include "tensorflow/core/framework/tensor.h"
#include <iostream>
int main() {
using namespace tensorflow;
using namespace tensorflow::ops;
using namespace std;
Scope root = Scope::NewRootScope();
// Matrix A = [3 2; -1 0]
auto A = Const(root, { {3.f, 2.f}, {-1.f, 0.f}});
// Vector b = [3 5]
auto b = Const(root, { {3.f, 5.f}});
// v = Ab^T
auto v = MatMul(root.WithOpName("v"), A, b, MatMul::TransposeB(true));
std::vector<Tensor> outputs;
ClientSession session(root);
// Run and fetch v
TF_CHECK_OK(session.Run({v}, &outputs));
// Expect outputs[0] == [19; -3]
LOG(INFO) << outputs[0].matrix<float>();
return 0;
cout<<"compiled correctly!"<<endl;
}
It is located in ~/Desktop/tensorflow/tensorflow/cc/example. My BUILD file - also in ~/Desktop/tensorflow/tensorflow/cc/example - reads:
cc_binary(
name = "example",
srcs = ["example.cc"],
deps = [
"//tensorflow/cc:cc_ops",
"//tensorflow/cc:client_session",
"//tensorflow/core:tensorflow",
],
)
I try to compile from ~/Desktop/tensorflow using:
bazel build tensorflow/cc/example/...
This is what i get:
INFO: Found 1 target...
Target //tensorflow/cc/example:example up-to-date:
bazel-bin/tensorflow/cc/example/example
INFO: Elapsed time: 0.381s, Critical Path: 0.00s
Then when i go to ~/Desktop/tensorflow/bazel-bin/tensorflow/cc/example and run:
./example
I get:

Any help would be much appreciate it as i'm trying to wrap my hands around this. Thanks for you patience.
