What it means

Error "translations rank must be statically known" thrown in tensorflow/models.

Source

Thrown at official/legacy/image_classification/augment.py:101

     [0 0 1]]

  Args:
    translations: The 2-element list representing [dx, dy], or a matrix of
      2-element lists representing [dx dy] to translate for each image. The
      shape must be static.

  Returns:
    The transformation matrix of shape (num_images, 8).

  Raises:
    `TypeError` if
      - the shape of `translations` is not known or
      - the shape of `translations` is not rank 1 or 2.
