+  * The other values OHWIo{interleave_by}i{block_by} describe the

+  * I' = first multiple of {block_by} s.t. I<=I'

+  *
+  * The access function of the tensor with layout
+  * OHWIo{interleave_by}i{block_by} and size O'HWI' is a 6-parameter
+  * access function, where the 6 parameters are computed as follows:
