question reason on a comment line in cumm/gemm float32, float32

[Kin-Zhang]

Recently, I run others works with spconv library (spconv 2.3.6 cumm 0.4.11) and get an error:

<return ALL_TENSOR_OP_MAP[(shape_tuple, dtype_ab, dtype_c)]> KeyError: ((16, 8, 8), float, float)

After a while, I notice that, on cumm libaray we comment this line, link to code

# ((16, 8, 8), dtypes.float32, dtypes.float32): MmaM16N8K8F32((8, 0)),

Any reason why we comment this line? Even though when changed spconv layer to spconv.ConvAlgo.Native it works again but results seem to be a big difference.

Looking forward to your reply. Thanks for maintenance these two libraries.
