apivovarov opened a new pull request, #12751:
URL: https://github.com/apache/tvm/pull/12751

   ### Description
   This PR adds TF [Bincount](https://www.tensorflow.org/api_docs/python/tf/raw_ops/Bincount) support. 
   
   Recently [DenseBincount support](https://github.com/apache/tvm/pull/12728) was added. Both `raw_ops.Bincount` and `raw_ops.DenseBincount` are used by `tf.math.bincount()` . One or another raw_op is used depending on the `tf.math.bincount()` parameters.
   
   #### Limitations:
   - Requires `relay.vm.compile` because internal data structures shapes depend on the input data content.
   
   #### Known issues:
   - Input array should not contain numbers outside of the range `[0, size-1]`. TVM `scatter_add` counts such values, but TF `DenseBincount` ignores them.
   - using tf.math.bincount with weights and axis=None need operator `UnsortedSegmentSum` to be implemented.
