     new 2c0a7c2  [TOPI] Add support for groupped conv3d (#9873)
2c0a7c2 is described below

commit 2c0a7c2a7e1df8203c14e4f0326a99aeaceb967a
Author: Tristan Konolige <tk...@octoml.ai>
AuthorDate: Fri Feb 18 14:18:01 2022 -0700

    [TOPI] Add support for groupped conv3d (#9873)
    
    * [TOPI] Add support for groupped conv3d
    
    Change conv3d to use generic conv implementation which supports groupped
    convolutions. Also, remove support for non-float16 tensorcore operations
    as they cause large degradation in accuracy. Generic conv now supports
    autoscheduler.
    
    * correct none check
    
    * add tests for floordiv simplification
    
    * fixed incorrect test for autoscheduler
    
    * formatting
    
    * add groups to winograd
    
    * fix tensorcore
    
    * manually simplify index instead of relying on simplifier
    
    * formatting
    
    * add groups argument to conv3d_ncdhw_winograd_without_weight_transform
    
    * formatting
