od_graph_def.ParseFromString(serialized_graph)

[hobbyist]

I am using this guy's code: https://stackoverflow.com/questions/4567...to-console
I get this error:

Error:
---> 28     od_graph_def.ParseFromString(serialized_graph)
DecodeError: Error parsing message

I have been searching google and stackoverflow for solutions, nothing works. I installed tf 2.0.0 ---> nothing, tf 1.15.1 ---> nothing, tf 2.5.0 ---> nothing.

I tried this (source: https://stackoverflow.com/questions/5761...o-attribut) :

tf.compat.v1.GraphDef()   # -> instead of tf.GraphDef()
tf.compat.v2.io.gfile.GFile()   # -> instead of tf.gfile.GFile()

--> nothing.

I tried this :

with tf.io.gfile.GFile(path, 'r') as fid:

--> nothing...

Countless candidate solutions I have tried, absolutely nothing! I work on google colab! What is wrong with this line??
