How to make 3 Fully connected layer

Hi, thanks for the code. However for my problem I have 3 fully connected layer, however when change 
`size_list = [(fc_unit_size, fc_unit_size)] * 4 `, `num_list = [4500, 4500,4500, 1148]`  I have this error _IndexError: index 3 is out of bounds for axis 0 with size 3

Do you know how to overcome this ?
Thanks !
