Predict function is showing error about vqa_demo HOT 8 CLOSED

It seems the model is not being loaded. Did you download the VGG weights file (see this) ?

from vqa_demo.

VGG weights file is downloaded and the image features are also extracted.
My theano version is 0.8.2.
Keras version is 1.0.2.
image_features dimenstion = (1, 4096)
question_features dimension = (1, 7, 300)

from vqa_demo.

1. First make sure you are running the code of this repo, which was updated to make changes to work with Keras 1+ (do a git pull origin master ) if you need to get the latest.
2. Run the command using following theano flag
    THEANO_FLAGS='exception_verbosity=high' python demo.py
   and then paste the error here. It seems some variable size mis-match but I do not get the same error.

from vqa_demo.

Now this error appears for

THEANO_FLAGS='exception_verbosity=high' python demo.py -image_file_name test.jpg -question "Is there a man in the picture?":

`Using Theano backend.

I tried to put spacy.set_lang_class('en_glove_cc_300_1m_vectors', 'vectors') but that didn't work [it worked for the jupyter demo; when the same error was over there]

from vqa_demo.

You might need to update your spacy or change the model, see here #6

from vqa_demo.

Try this two commands to get your glove vectors running

sputnik --name spacy --repository-url http://index.spacy.io install en==1.1.0
sputnik --name spacy en_glove_cc_300_1m_vectors

from vqa_demo.

Thank you :) issue is solved. I added this line in the demo.py after importing spacy.

spacy.set_lang_class('en_glove_cc_300_1m_vectors', None)

from vqa_demo.

Thanks @anujshah1003 and @iqbal-chowdhury
