Functions

decode_and_crop_jpeg(...)卖空期货: Decode and Crop a JPEG-encoded image to a uint8 tensor.

decode_base64(...)卖空期货: Decode web-safe base64-encoded strings.

decode_bmp(...)卖空期货: Decode the first frame of a BMP-encoded image to a uint8 tensor.

decode_image(...): Function for decode_bmp, decode_gif, decode_jpeg, and decode_png.

decode_jpeg(...): Decode a JPEG-encoded image to a uint8 tensor.

decode_json_example(...): Convert JSON-encoded Example records to binary protocol buffer strings.

decode_png(...): Decode a PNG-encoded image to a uint8 or uint16 tensor.

decode_proto(...)卖空期货: The op extracts fields from a serialized protocol buffers message into tensors.

decode_raw(...)卖空期货: Convert raw byte strings into tensors.

deserialize_many_sparse(...): Deserialize and concatenate SparseTensors卖空期货 from a serialized minibatch.

encode_base64(...): Encode strings into web-safe base64 format.

encode_jpeg(...): JPEG-encode an image.

encode_proto(...)卖空期货: The op serializes protobuf messages provided in the input tensors.

extract_jpeg_shape(...): Extract the shape information of a JPEG-encoded image.

is_jpeg(...)卖空期货: Convenience function to check if the 'contents' encodes a JPEG image.

match_filenames_once(...)卖空期货: Save the list of files matching pattern, so it is only computed once.

matching_files(...)卖空期货: Returns the set of files matching one or more glob patterns.

parse_example(...): Parses Example protos into a dict of tensors.

parse_sequence_example(...): Parses a batch of SequenceExample protos.

parse_single_sequence_example(...): Parses a single SequenceExample proto.

parse_tensor(...): Transforms a serialized tensorflow.TensorProto proto into a Tensor.

read_file(...)卖空期货: Reads and outputs the entire contents of the input filename.

serialize_many_sparse(...): Serialize N-minibatch SparseTensor into an [N, 3] Tensor.

serialize_sparse(...): Serialize a SparseTensor into a 3-vector (1-D Tensor) object.

serialize_tensor(...)卖空期货: Transforms a Tensor into a serialized TensorProto proto.

write_file(...): Writes contents to the file at input filename. Creates file and recursively

write_graph(...)卖空期货: Writes a graph proto to a file.
