For the hand-craft assemby code, it usual not have fixed tensor dimension.
For example, we have matrix multply assembly code, it just need X and Y dimension meet certain requirement, like X % 4 = 0, Y % 4 = 0. But for TVM I only know the fixed dimension method, in other words, we need to specify the X dimension to 128, Y to 64, if we want to use TVM generated assembly code, we need to write the python code again, does autoTVM again.
If there is one method currently that I am not know, please help share method that can generate tensor dimensions are not fixed, only some limitations on dimension, that is great.
