Run captioning to my own images.

[gxskar]

Sorry for the stupid question, but I am very new to machine learning applications. I have run your code until the point of having a checkpoint. I now want to produce a list of captions from some images that I have gathered. What are the steps for doing so? Again sorry, and thanks.

I have been working on this tutorial for the past two weeks. As far as I understand, the forward method of the decoder cannot be used for inference, since it makes use of the technique called "teacher forcing". Basically, this means that to evaluate the model, you have to feed it not only an image, but also a caption !

This seem to defeat the purpose of modeling, because we would need to have a proper caption to generate one. This issue is actually adressed in the remarks :

Do you already have a trained model? If yes, then simply running caption.py on your images should work fine. This is because we're using beam search in the evaluation mode (i.e. it doesn't need a caption for the image. Just the images should be sufficient)

Sorry, When I run caption.py, there is an ERROR, the decoder has no attribute decode_step, how to handle this issue?

[alexandre-blanc]

Could you show us the exact commands you used to :

1. obtain the checkpoint
2. run caption.py

as well as the full output in the terminal (i.e. the complete error message) ?

Warning should be okay for running the code, which is caused by the Scipy version.
