+### DebugNodeInputsOutputs
+OnnxRuntime supports build options for enabling debugging of intermediate tensor shapes and data.
+#### Build Instructions
+##### Set onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=1
+Dump tensor input/output shapes for all nodes to stdout.
+```
+# Linux
+./build.sh --cmake_extra_defines onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=1
+# Windows
+.\build.bat --cmake_extra_defines onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=1
+```
+##### Set onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=2
+Dump tensor input/output shapes and output data for all nodes to stdout.
+```
+# Linux
+./build.sh --cmake_extra_defines onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=2
+# Windows
+.\build.bat --cmake_extra_defines onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=2
+```
+##### Set onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=0
+To disable this functionality after previously enabling, set onnxruntime_DEBUG_NODE_INPUTS_OUTPUTS=0 or delete CMakeCache.txt.
