Reads a tensor stored in one or several files. If there are several files (for
  instance because a tensor was saved as slices), `file_pattern` may contain
  wildcard symbols (`*` and `?`) in the filename portion only, not in the
  directory portion.

If a `file_pattern` matches several files, `preferred_shard` can be used to hint
  in which file the requested tensor is likely to be found. This op will first
  open the file at index `preferred_shard` in the list of matching files and try
  to restore tensors from that file.  Only if some tensors or tensor slices are
  not found in that first file, then the Op opens all the files. Setting
  `preferred_shard` to match the value passed as the `shard` input
  of a matching `Save` Op may speed up Restore.  This attribute only affects
  performance, not correctness.  The default value -1 means files are processed in
  order.

See also `Save`.

Args:
    filename: A `Tensor` of type `string`.
      Must have a single element. The name of the file to which we write the
      tensor.
    tensor_names: A `Tensor` of type `string`.
