tensorflow:: ops:: Restore
#include <io_ops.h>
Restores a tensor from checkpoint files.
Summary
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.

.
Args:
- scope: A Scope object
- file_pattern: Must have a single element. The pattern of the files from which we read the tensor.
- tensor_name: Must have a single element. The name of the tensor to be restored.
- dt: The type of the tensor to be restored.
Optional attributes (see Attrs
):
- preferred_shard: Index of file to open first if multiple files match
file_pattern
.
Returns:
Output
: The restored tensor.
