This seems reasonable. I'll check with the team, but I don't think there would be objections to this. Would you mind adding a small test for it? There seems to already be a test for using an explicit writer:

Sounds very reasonable. |

Just a nitpick here but it would be nice to keep the formatting consistent

Motivation for features / changes
Most other Tensorflow functions accept Paths in other form than strings.
This small change makes the plugin more consistent and users do not need to cast their Path objects to string manually.
Technical description of changes
elif isinstance(writer, os.PathLike):
self._writer = tf.compat.v2.summary.create_file_writer(os.fsdecode(writer))
Detailed steps to verify changes work correctly (as executed by you)
Barely tested to be honest. Just ran the tutorial code here: https://www.tensorflow.org/tensorboard/hyperparameter_tuning_with_hparams
with my version
Alternate designs / implementations considered
Once all Tensorflow functions accept pathlikes instead of just strings the distinction between str and PathLike will be unnecessary.
