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 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
