Description

Impact

If tf.summary.create_file_writer is called with non-scalar arguments code crashes due to a CHECK-fail.

import tensorflow as tf
import numpy as np
tf.summary.create_file_writer(logdir='', flush_millis=np.ones((1,2)))

Patches

We have patched the issue in GitHub commit 874bda09e6702cd50bac90b453b50bcc65b2769e (merging #51715).

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.
