Pass convLayer output 4D tensor to ConvLstm Layer input (5D tensor)

Hello everyone,

I am adding an ConvLstm layer after conv13 layer of mobilenet which outputs a 4d tensor(batch_size,nb_of_features,width,height) and I want to pass this tensor to a ConvLstm layer that takes tensor of dimensions(batch_size,seq_length,nb_of_features,width,height) but I dont get how I should do that, how to convert this 4d tensor to 5d tensor and how to fill it correctly, there is something that isnt really clear for me.
Thanks for your help !
