* Correct a couple of format stringsHEADmasterGravatar Benjamin Barenblat2018-10-10
| | | | | | | Change a couple of fscanf-style format strings to use the format macro constants defined in cinttypes. This quashes -Wformat. PiperOrigin-RevId: 216545604

* Add Metadata object for RecordReader and associated stats computing /Gravatar Vijay Vasudevan2018-09-23
| | | | | | | | | | | | | | | | | MD fetching method. TFRecord files do not contain a file-level header that describes the MD of the file. To avoid backwards compatibility issues, we add a lightweight function that computes the statistics over the file once and caches the result for future calls. A future implementor could do a better job of computing GetMetadata() by having the RecordWriter emit these entries during writing so that GetMetadata() only reads. Doing so will require additional backwards compatibility checks to ensure that the function works both for old TFRecords and the new format. PiperOrigin-RevId: 214178704

* Alias tensorflow::gtl::InlinedVector to absl::InlinedVectorGravatar Benjamin Kramer2018-09-05
| | | | PiperOrigin-RevId: 211639440
* There were two different error reporting formats within TensorFlow: `{{key ↵Gravatar A. Unique TensorFlower2018-09-04
| | | | | | value}}` and `^^key:value^^`. This change consolidate these two format. PiperOrigin-RevId: 211550259

* | This change started with an intention of adding an attribute to cast ops to ↵Gravatar A. Unique TensorFlower2018-07-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | decide whether bfloat16 casts should use truncation or rounding. This is a preparatory change before we switch the default float ==> bfloat16 cast to use rounding instead of truncation. The attribute added can then be specified on casts that rely on the truncation, e.g., the TensorFlow send/receive operations. It later emerged that the choice of doing truncation is useful more generally. Therefore, this change allows the new attribute to be used by all relevant casts to use truncation instead of rounding.
