|  |  | 
|  | ### [edge_detection\.ipynb](edge_detection.ipynb) | 
|  |  | 
|  | Constructs a TF module for performing image edge detection and runs it using | 
|  | IREE | 
|  |  |

|  |  | 
|  | ### [low_level_invoke_function\.ipynb](low_level_invoke_function.ipynb) | 
|  |  | 
|  | Shows off some concepts of the low level IREE python bindings | 
|  |  | 
|  | [](https://colab.research.google.com/github/google/iree/blob/master/colab/low_level_invoke_function.ipynb) | 
|  |  | 
|  | ### [simple_tensorflow_module_import\.ipynb](simple_tensorflow_module_import.ipynb) | 
|  |  | 
|  | Defines a simple TF module, saves it and loads it in IREE | 
|  |  |
