constructor, nor expose it as a @property.
*   The behavior of tf.gather is now correct when axis=None and batch_dims<0.
*   Only create a GCS directory object if the object does not already exist.
*   In `map_vectorization` optimization, reduce the degree of parallelism in the
    vectorized map node.
*   Bug fix: loss and gradients should now more reliably be correctly scaled
    w.r.t. the global batch size when using a tf.distribute.Strategy.

- Reverts breaking change to inline AzureFile volumes in v1.19.7-v1.19.9; referenced secrets are now correctly searched for in the same namespace as the pod as in previous releases.
