如何修复来自tensorflow.python.ops导入gen_logging_ops```库的`错误？

Question

下面是代码片段，我想在其中构建一个图像摘要。

import tensorflow as tf
from tensorflow.python.ops import gen_logging_ops
from tensorflow.python.framework import ops as _ops

def build_image_summary():
    log_image_data = tf.placeholder(tf.uint8, [None, None, 3])
    log_image_name = tf.placeholder(tf.string)
    log_image = gen_logging_ops._image_summary(log_image_name, tf.expand_dims(log_image_data, 0), max_images=1)    
    _ops.add_to_collection(_ops.GraphKeys.SUMMARIES, log_image)
    return log_image, log_image_data, log_image_name

但执行上面的代码时，我的属性错误如下：

AttributeError: module 'tensorflow.python.ops.gen_logging_ops' has no attribute '_image_summary'

我将gen_logging_ops._image_summary更改为gen_logging_ops.summary.image，但仍然收到新的错误！我使用的是tensorflow 1.15.2版。如何解决此错误？

Answer 1

tf_op_gen_wrapper_py bazel规则是生成gen_文件的规则。如上所述，在此答案中，此规则生成此库中定义的ops的所有python包装器：

py_library(
    name = "logging_ops",
    srcs = ["ops/logging_ops.py"],
    srcs_version = "PY2AND3",
    deps = [
        ":framework_for_generated_wrappers",
        ":logging_ops_gen",
        ":util",
    ],
)

在logging_ops的情况下有一个间接的原因:对tf_op_gen_wrapper_py的调用隐藏在tf_gen_op_wrapper_private_py中：

 tf_gen_op_wrapper_private_py(
    name = "logging_ops_gen",
    visibility = [
        "//learning/brain/python/ops:__pkg__",
        "//tensorflow/python/kernel_tests:__pkg__",
    ],
)

Answer 2

从gen_logging_ops._image_summary替换为gen_logging_ops.image_summary。这解决了我的问题！
