@rogday Hi, it doesn't seem easy to generate a const input node for this test. This may take much more time than it takes to fix the issue. Do you have some suggestions or can I not generate the test? |

Hey @WanliZhong! I didn't work with TF in a long time, but I have an old snippet where I needed to cut the model for debugging purposes. You could try to do the same. Not sure if it still works or if there are any bugs :D with tf.gfile.FastGFile('model.pb', 'rb') as f:
graph_def = tf.GraphDef()
graph_def.ParseFromString(f.read())
nodes = [x for x in graph_def.node]
def save_graph(graph_def, node_name):
visited = set()
name_to_node = dict([(node.name, node) for node in nodes])
def make_graph(node_name):
nonlocal visited
if node_name in visited:
return []
visited.add(node_name)
node = name_to_node[node_name]
graph = [node]
for child_name in node.input:
graph += make_graph(child_name)
return graph
del graph_def.node[:]
new_nodes = make_graph(node_name)
graph_def.node.extend(new_nodes)
table = node_name.maketrans("/", "_")
tf.train.write_graph(graph_def, "output_dir", 'new_model.pb', as_text=False)If you don't manage to cut the model, I think it's okay to merge without test if the problem disappears. |
