Train and Evaluate

• Download and extract 'glove.6B.100d.txt' link
• Download the MSVD dataset and create corresponding pickle files using vid2frames.ipynb. Split the data in train-test-val sets.

  Alternate step: Download and extract 'data_pickle.zip'. This compressed file already contains the pickles files of MSVD dataset

• run the train.ipynb file

  This file has a detailed list of options. Change the options to adjust the model according to requirements

• Train and evaluation codes are inside the python notebook
