Imae Captioning Pickle Error

[ahkarami]

Hi,
I want to use the pre-trained models (without download MS-COCO Dataset). when i run the
python2 sample.py --image='png/example.png'
I got this error:

Traceback (most recent call last):
  File "sample.py", line 97, in <module>
    main(args)
  File "sample.py", line 37, in main
    vocab = pickle.load(f)

    return Unpickler(file).load()

@ahkarami You should save the vocabulary file to './data/vocab.pkl`. If you want to use the pretrained model, download the vocab file and unpack it as mentioned in ReadME.md.

@yunjey Thank you for your response. The code works correctly.
