Division by zero in `ParallelConcat`
Reported by github_m · Published November 5, 2021
tensorflow-gpu is fixed in f2c3931113eaafe9ef558faaddd48e00a6606235, 2.7.0, 2.6.1 and 2 more (PyPI)
TensorFlow is an open source platform for machine learning. In affected versions the implementation of `ParallelConcat` misses some input validation and can produce a division by 0. The fix will be included in TensorFlow 2.7.0. We will also cherrypick this commit on TensorFlow 2.6.1, TensorFlow 2.5.2, and TensorFlow 2.4.4, as these are also affected and still in supported range.
