# tf_conceptual_graph

Create tensorflow(1.x) conceptual graph. Conceputual graph is not aimed to reconstruct a neural network. The main purpose of this conceputual graph is for treating a neural network as a heterogeneous graph. Once we can treat neural networks as heterogeneous graphs, we can apply graph neural network methods for them to predict inference results from trained neural networks. From the view point, we can optimize neural network structures.

## Installtion

```shell

$ pip install tfcg

```

## Usage

read a graph_def object from object api(`sess.graph_def`)

```python

import numpy as np

import tensorflow as tf

import tfcg

with tf.Graph().as_default() as graph:

    model = tf.keras.Sequential()

    x = np.random.rand(128, 28, 28, 3)

    model.add(tf.keras.layers.Conv2D(16, 3, input_shape=[28, 28, 3], name='conv1'))

    model.add(tf.keras.layers.Conv2D(32, 1, name='conv2'))

    model.add(tf.keras.layers.Conv2D(64, 2, name='conv3'))

    model.add(tf.keras.layers.Conv2D(128, 2, name='conv4'))

    model.add(tf.keras.layers.Flatten())

    model.add(tf.keras.layers.Dense(32, name='dense1'))

    model.add(tf.keras.layers.ReLU())

    model.add(tf.keras.layers.Dense(16, name='dense2'))

    x_p = tf.placeholder(tf.float32, [None, 28, 28, 3], name='input')

    out_p = model(x_p)

    with tf.Session() as sess:

        sess.run(tf.global_variables_initializer())

        o = sess.run(out_p, feed_dict={x_p: x})

        _ = tf.identity(o, name="output")

        tf.io.write_graph(sess.graph, './', 'train.pbtxt')

        parser = tfcg.from_graph_def(sess.graph_def)

        parser.dump_json("conceptual_graph.json")

        parser.dump_img("output.png")

```

read a graph from a file, After dumpping a tensorflow graph file.

```python

import tfcg

parser = tfcg.from_file("./train.pbtxt")

parser.dump_json("conceptual_graph.json")

mparser.dump_img("output.png")

```
