I have the following dataframe containing training data that I have been using to perform a regression task using CNN + FC :

     fileName  var_t+15m  var_t+30m  var_t+45m  var_t+60m  var_t+90m  var_t+120m  var_t+180m  var_t+240
id

The task consists in predicting a certain variable at t+X where X goes from 15 minutes up to 240 minutes. So this is a regression task where my training input consists in timestamped picture.

In order to work with these data, I was until now using the .flow_from_dataframe method from Keras in order to perform data augmentation/pre-processing easily and to avoid loading the entire training set consisting of pictures inside the memory.

Up until now I did not leverage the time information and to do so I would like to try the convLSTM model available in Keras. Howevever I am very unfamilar with working with time series.

Has someone used the Keras convLSTM layer combined with the .flow_from_dataframe function ? I am unsure how to structure my data for this setup (convLSTM + .flow_from_dataframe) and I could not find an example on the internet.
