Question

我正在尝试使用.tflite在移动设备上创建中文分割器，jeiba库需要一个字符串并给出一个生成器，然后将该生成器放入Autograph中并转换为.tflite。我该如何解决错误。任何帮助表示赞赏。

def segmentation(sentence):
    segmented = jieba.cut(sentence, cut_all=False)
    segmented_text = (" ".join(segmented))
    return segmented_text

tf_square_if_positive = autograph.to_graph(segmentation)

def freeze_session(session, keep_var_names=None, output_names=None, clear_devices=True):
    from tensorflow.python.framework.graph_util import convert_variables_to_constants
    graph = session.graph
    with graph.as_default():
        freeze_var_names = list(set(v.op.name for v in tf.global_variables()).difference(keep_var_names or []))
        output_names = output_names or []
        output_names += [v.op.name for v in tf.global_variables()]
        input_graph_def = graph.as_graph_def()
        if clear_devices:
            for node in input_graph_def.node:
                node.device = ""
        frozen_graph = convert_variables_to_constants(session, input_graph_def,
                                                      output_names, freeze_var_names)
        return frozen_graph

from keras import backend as K

custom_input_tensor = tf.placeholder(tf.string, shape=(1, 13))
output_tensor = tf_square_if_positive(custom_input_tensor)

frozen_graph = freeze_session(K.get_session(), output_names=[output_tensor.op.name])

tflite_model = tf.contrib.lite.toco_convert(frozen_graph, [custom_input_tensor], [output_tensor])
open("./temp.tflite", "wb").write(tflite_model)

提高：

如何在Tensorflow中使用Jieba（中文分割器）并创建.tflite？
