How to check or view the intermediate results or output of a network?

as the title, take inception v3 for example, so how to check or print the intermediate output ?

You could register forward hooks as shown in this example.
If you would like to store the activation in a dict, have a look at this example.

Thank you. That is exactly what I need.
another question. how to display the intermediate results?

You can just print the activation from your dict.
If you would like to visualize them, just call .numpy() on the activation and you can use e.g. matplotlib to visualize the activation maps.

emmm, matplotlib! thanks!
