Restores a tensor from checkpoint files.
tf.raw_ops.Restore(
file_pattern, tensor_name, dt, preferred_shard=-1, name=None
)
Used in the notebooks
Used in the tutorials |
---|
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.

A Tensor of type string .
Must have a single element. The pattern of the files from
which we read the tensor.

|
preferred_shard
|
An optional int . Defaults to -1 .
Index of file to open first if multiple files match
file_pattern .
