🚧 TensorBoard is migrating to Polymer 3 🧼

[stephanwlee]

Due to our difficulty in maintaining infrastructure for our HTML import based Polymer, TensorBoard is migrating to all JS/TS style Polymer.

We expect the migration to take about one full week (2020/07/27-2020/08-03), so we would appreciate if you do not make changes to the Polymer based TensorBoard components.

Will post updates and revised ETAs.

Update to the migration:

We made great progress last week but we are not done yet. We are still waiting to finish below:

• plugins/distribution (migrate: plugins/distribution/polymer3 #3980)
• plugins/graph (migrate: convert graph externally part 2 #3932)
• plugins/histogram (migrate: plugins/histogram/polymer3 #3959)
• plugins/hparams (Migrate plugins/hparams #4010)
• plugins/image (migrate: tf_image_dashboard #3986)
• plugins/mesh (polymer3: integrate mesh plugin to the migrated code #4011)
• plugins/pr_curve
• plugins/scalars (migrate: plugins/scalar/polymer3 #3972)
• functional tests

Our new estimate is EOW (August 10th). Wish us luck! 🤞

@rmothukuru Is there anything wrong with pinning? We would like to tell our contributors that they should not make the changes until the migration is over.

@stephanwlee,
I'm sorry. It was accidentally done. Pinned it now. Thanks!

Happy to report that the Polymer migration is done. However, we have not finished the cleanup to remove Polymer 2 code. We will definitely appreciate it if you can hold of making contribution until we can reshuffle our directories.
