A visualization tool to show a ascii graph from Graphviz-Dot-file or Tensorflow
Project description
stacked-dag for python
Ascii DAG for visualization of dataflow
stacked-dag can show Ascii-DAG(Directed acyclic graph) from a Dot file of graphviz. Dataflow’s direction is from top to bottom. ‘o’ means a node. A label of the node is shown to the left side. Other characters are edges of DAG.
A sample of DAG is below.
o o l0,l4 |/ o l1 | o l2 | o l3
Usage with dot
Write a Dot file of graphviz.
$ cat > sample.dot digraph graphname { 0 [label="l0"]; 1 [label="l1"]; 2 [label="l2"]; 3 [label="l3"]; 4 [label="l4"]; 0->1; 1->2; 2->3; 4->1; }
Show ascii DAG by following command.
$ python stackeddag.py sample.dot o o l0,l4 |/ o l1 | o l2 | o l3
Usage with tensorflow
import tensorflow as tf import stackeddag.tf as sd def mydataflow(): a = tf.constant(1,name="a") b = tf.constant(2,name="b") c = tf.add(a,b,name="c") return tf.get_default_graph() print(sd.fromGraph(mydataflow()),end="")
The output is below.
o o a,b |/ o c
Another sample
$ python stackeddag.py sample/test.dot o | o |\ o | | |\ o o | |\ \ \ | | |\ \ | | | | |\ o o o o o | |/ /_/ / / | | / / o o o o |/_/_/ o
