Passing labels for tiny-yolo model using keras, expected activation_7 to have 4 dimensions, but got array...

I am trying to pass my own data from scratch through the tiny-YOLO architecture built using Keras.
In my understanding,
the labels for each image should be of the form:
[p_c, b_x, b_y, b_h, b_w, c_1, c_2] or variants for other cases.
In this case, there are 7 elements in each label for an image.
Final layer is a convolutional layer with output (3, 3, 7), with each channel representing the label.
However, during training and at the final layer, the linear activation of the convolutional layer expects 4 dimensions whilst the labels I've provided is of the form (m, 7) as explained above. (note: m = number of training data).
What should I do to fix this? Any help will be appreciated!
Below is a model summary and the error at the bottom.
