/TensorFlow 2.4


Restores tensors from a V2 checkpoint.

For backward compatibility with the V1 format, this Op currently allows restoring from a V1 checkpoint as well:

  • This Op first attempts to find the V2 index file pointed to by "prefix", and if found proceed to read it as a V2 checkpoint;
  • Otherwise the V1 read path is invoked. Relying on this behavior is not recommended, as the ability to fall back to read V1 might be deprecated and eventually removed.

By default, restores the named tensors in full. If the caller wishes to restore specific slices of stored tensors, "shape_and_slices" should be non-empty strings and correspondingly well-formed.

Callers must ensure all the named tensors are indeed stored in the checkpoint.

prefix A Tensor of type string. Must have a single element. The prefix of a V2 checkpoint.
tensor_names A Tensor of type string. shape {N}. The names of the tensors to be restored.
shape_and_slices A Tensor of type string. shape {N}. The slice specs of the tensors to be restored. Empty strings indicate that they are non-partitioned tensors.
dtypes A list of tf.DTypes that has length >= 1. shape {N}. The list of expected dtype for the tensors. Must match those stored in the checkpoint.
name A name for the operation (optional).
A list of Tensor objects of type dtypes.
