Can't seem to get sample_speaker.py to generate text for new images

[texturejc]

I wish to generate caption text for images that I'll be providing. My understanding is that sample_speaker.py will do this. However, when I run it I get an error. Here's what I run in terminal, with the relevant parts of config.json.txt changed.

python sample_speaker.py -speaker-saved-args config.json.txt -speaker-checkpoint best_model.pt -img-dir image_folder -out-file /Outputs/results.pkl

When I do this, I get:

RuntimeError: Error(s) in loading state_dict for ModuleDict:
    size mismatch for decoder.word_embedding.weight: copying a param with shape torch.Size([14469, 128]) from checkpoint, the shape in current model is torch.Size([35466, 128]).
    size mismatch for decoder.next_word.weight: copying a param with shape torch.Size([14469, 512]) from checkpoint, the shape in current model is torch.Size([35466, 512]).
    size mismatch for decoder.next_word.bias: copying a param with shape torch.Size([14469]) from checkpoint, the shape in current model is torch.Size([35466]).

Can you advise what I'm doing wrong here? I can't quite get to the bottom of it. Thanks!

Hi, you are right the sample_speaker.py can be used to create captions for whatever images you want to. However, to do this you need to provide a .csv file that informs the code about which images you intend to caption.

Specifically, you need to pass this .csv per the "-custom-data-csv" argument. Please have a look at the function "custom_grounding_dataset_similar_to_affective_loader" in artemis/in_out/datasets.py for more info. In a gist, the custom .csv has to include the filenames and optionally the grounding emotion (if you are using a system that takes emotion-grounding into account).

Last, the error you get is about something else. It tells you that the loaded model is using a decoder with 14469 tokens. That's how many we use in the published pretrained models. Apparently, you are using here a vocabulary that contains all tokens possible for ArtEmis which won't match the one we used for training deep-nets.

Thanks for the clarification, appreciated. I've now supplied the relevant csv. Can I ask one further question? You say:

Can I ask how I might use the right decoder so as to avoid this error? I'm using the best_model.pt provided for download, so I don't know where the vocabulary discrepancy is coming from. So far as I'm aware, I'm not doing anything that could result in there being a mismatch, so I'm not sure how to solve this problem. Any steer on this would be appreciated!

Hello, sorry for the long-due reply. Did you figure it out?

Judging by the numbers of your tensors, I think you are pointing via the sample_speaker.py (via the passed config.json.txt) to a local -data-dir that stores the vocabulary.pkl that you generated for analysis, and not a reduced-sized one as we do when we train deep-nets i.e., the one that will be created by running the preprocess_artemis_data.py with the --preprocess-for-deep-nets flag set to True ( in step-1). Right?

If that is the case, you need to rerun the preprocess_artemis_data.py with the --preprocess-for-deep-nets True and then update the config.json.txt of the pretrained model to point to that new output directory where you will save the preprocessed results.

Last, a) I will go ahead and upload the vocabulary.pkl I used to the page, to make things easier for the next users. However, the vocabulary used should be identical to what you will get if you follow Step1 as I describe above. b) please, if possible, send to me an email at optas@stanford.edu - I want to ask 1-2 things to see better what users are facing. Thank you!

@optas In my experience, running the preprocess_artemis_data.py file with the --preprocess-for-deep-nets True setting results in a vocabulary file with 14468 entries, whereas your pretrained model has a vocabulary of 14469. I cannot for the life of me figure out the source of this discrepancy, and for this reason I cannot use your pretrained neural speaker. I don't think you have uploaded the vocabulary.pkl file you used either, I cannot find it anywhere.

Hi @ege-kaya I run the preprocess_artemis_data.py without an issue. Here is what I did (setting output dir to be preprocess-for-deep-nets), and the output.

I do not think optas has to upload the vocabulary.pkl, the vocabulary.pkl lies in the preprocessed folder. In my case, this is /home/yiren/artemis/preprocess-for-deep-nets/vocabulary.pkl.

When you run his notebook evaluate_sampled_captions.ipynb, you edit the paths accordingly:

# top-image dir
wiki_art_img_dir = '/home/yiren/artemis/wikiart'

# output of preprocess_artemis_data.py
references_file = '/home/yiren/artemis/preprocess-for-deep-nets/artemis_gt_references_grouped.pkl'

# to compute the emotion-alignment you need a text2emo classifier, provide one.
text2emo_path = '/home/yiren/artemis/text2emo/best_model.pt'

# this is what is the vocabulary used by the text2emo classifier which in our case is equal to what was 
# used by the neural speaker(though this is not necessary as the input of the text2emo from the speaker 
# is human sentences, so it could decode them anyway.
# this is also generated as an ouput of preprocess_artemis_data.py
vocab_path = '/home/yiren/artemis/preprocess-for-deep-nets/vocabulary.pkl'

Did you figure this out? I'm also getting 14468

Hi, setting the exact values mentioned in the comments in setup.py seems to be doing the trick for me. I was just able to replicate this in a google colab instance.
