In core/kernels/list_kernels.cc's TensorListReserve
, num_elements
is assumed to be a tensor of size 1. When a num_elements
of more than 1 element is provided, then tf.raw_ops.TensorListReserve
fails the CHECK_EQ
in CheckIsAlignedAndSingleElement
.
import tensorflow as tf
tf.raw_ops.TensorListReserve(element_shape=(1,1), num_elements=tf.constant([1,1], dtype=tf.int32), element_dtype=tf.int8)
We have patched the issue in GitHub commit b5f6fbfba76576202b72119897561e3bd4f179c7.
The fix will be included in TensorFlow 2.10.0. We will also cherrypick this commit on TensorFlow 2.9.1, TensorFlow 2.8.1, and TensorFlow 2.7.2, as these are also affected and still in supported range.
