# 需要导入模块: from utils import util [as 别名]
# 或者: from utils.util import is_np_array [as 别名]
def inference(
self, inference_input, checkpoint_path, batch_size=None, **kwargs):
"""Defines 3 of modes of inference.
Inputs:
* Mode 1: Input is an input_fn.
* Mode 2: Input is a TFRecord (or list of TFRecords).
* Mode 3: Input is a numpy array holding an image (or array of images).
Outputs:
* Mode 1: this returns an iterator over embeddings and additional
metadata. See
https://www.tensorflow.org/api_docs/python/tf/estimator/Estimator#predict
for details.
* Mode 2: Returns an iterator over tuples of
(embeddings, raw_image_strings, sequence_name), where embeddings is a
2-D float32 numpy array holding [sequence_size, embedding_size] image
embeddings, raw_image_strings is a 1-D string numpy array holding
[sequence_size] jpeg-encoded image strings, and sequence_name is a
string holding the name of the embedded sequence.
* Mode 3: Returns a tuple of (embeddings, raw_image_strings), where
embeddings is a 2-D float32 numpy array holding
[batch_size, embedding_size] image embeddings, raw_image_strings is a
1-D string numpy array holding [batch_size] jpeg-encoded image strings.
Args:
inference_input: This can be a tf.Estimator input_fn, a TFRecord path,
a list of TFRecord paths, a numpy image, or an array of numpy images.
checkpoint_path: String, path to the checkpoint to restore for inference.
batch_size: Int, the size of the batch to use for inference.
**kwargs: Additional keyword arguments, depending on the mode.
See _input_fn_inference, _tfrecord_inference, and _np_inference.
Returns:
inference_output: Inference output depending on mode, see above for
details.
Raises:
ValueError: If inference_input isn't a tf.Estimator input_fn,
a TFRecord path, a list of TFRecord paths, or a numpy array,
