我按照指示去做 here

模型是使用 tf.estimator API ,它将根据自动保存模型文件 this page .

tensorflowjs 使用pip,我在运行转换脚本时出现以下错误:

$ tensorflowjs_converter     --input_format=tf_saved_model     --output_node_names='DeepWater'     /home/sterengiannini/deepwater/model-js-import-test     /home/sterengiannini/deepwater/web-model
Using TensorFlow backend.

    raise IOError("SavedModel file does not exist at: %s" % saved_model_dir)
IOError: SavedModel file does not exist at: /home/sterengiannini/deepwater/model-js-import-test

以下是模型文件夹中的文件:

$ ls model-js-import-test/
graph.pbtxt  model.ckpt-312.data-00000-of-00001  model.ckpt-312.index  model.ckpt-312.meta

看起来模型没有以正确的格式保存。您应该在模型文件夹中看到如下内容( see Structure of a SavedModel directory ):

assets/
assets.extra/
variables/
    variables.data-?????-of-?????
    variables.index
saved_model.pb|saved_model.pbtxt

例如,如果您使用的是tf.estimator API,则需要使用以下内容导出模型( see Using SavedModel with Estimators

estimator.export_savedmodel(export_dir_base, serving_input_receiver_fn)
