## Overview

TensorFlow is an end-to-end machine-learning platform with Python and C++ APIs. The principal workflow is to submit tensor operations, execute them on available devices, and receive tensor results; training can add distribution and gradient computation, while compilation and model export support deployment. The graph also includes profiling, SavedModel, and filesystem capabilities visible in the tree. The README documents the APIs and product scope, but most implementation files were not sampled, so the subsystem links are architectural rather than verified call-by-call traces.

Main entry points: [`tensorflow/cc/framework/ops.cc`](https://github.com/saikumarchalla/tensorflow/blob/master/tensorflow/cc/framework/ops.cc) (C++ operations), [`tensorflow/__init__.py`](https://github.com/saikumarchalla/tensorflow/blob/master/tensorflow/__init__.py) (Python API), [`tensorflow/c/kernels.cc`](https://github.com/saikumarchalla/tensorflow/blob/master/tensorflow/c/kernels.cc) (Kernel interface), [`tensorflow/c/experimental/filesystem/modular_filesystem.cc`](https://github.com/saikumarchalla/tensorflow/blob/master/tensorflow/c/experimental/filesystem/modular_filesystem.cc) (Filesystem plugins)
