The RaggedCountSparseOutput
does not validate that the input arguments form a valid ragged tensor. In particular, there is no validation that the splits
tensor has the minimum required number of elements. Code uses this quantity to initialize a different data structure:
https://github.com/tensorflow/tensorflow/blob/0e68f4d3295eb0281a517c3662f6698992b7b2cf/tensorflow/core/kernels/count_ops.cc#L241-L244
Since BatchedMap
is equivalent to a vector, it needs to have at least one element to not be nullptr
. If user passes a splits
tensor that is empty or has exactly one element, we get a SIGABRT
signal raised by the operating system.
We have patched the issue in 3cbb917b4714766030b28eba9fb41bb97ce9ee02 and will release a patch release.
We recommend users to upgrade to TensorFlow 2.3.1.
