Training

how do I train in my own dataset?

You need to extract video features.
Given a video, I slice it to 80 slices equally.
Then feed 80 slices into VGG16 net, and extract the last fully connected layer's output.
So the feature of a video will be a matrix with shape 80x4096.

Thanks for the great code!
Are there any scripts for video feature extraction and other pre-processing steps that can be shared? These would be very helpful in running the code on other datasets.
Thanks in advance.

I was able to create the npy files for train features. When I start the training, I get this error-

ValueError: Variable Wemb/Adam/ does not exist, or was not created with tf.get_variable(). Did you mean to set reuse=None in VarScope?

I am using Tensorflow version 1.1.0. There seems to be a workaround here-
tensorflow/tensorflow#6220

But I am unable to add to the train.py file. Any help is appreciated.
Thanks.
