tensorflow2错误 - 在函数调用tf.summary.trace_exp中无法创建插件/概要/目录

Question

使用tensorflow2，我尝试使用函数调用记录tensorflow的执行tf.summary.trace\u导出（）并在张力板图中查看。但是，在调用tf.summary.trace_export(name="my_func_trace", step=0, profiler_outdir=logdir)时

tensorflow.python.framework.errors_impl.NotFoundError: Failed to create a directory: logs/func/20191105-014756\plugins\profile\2019-11-05_01-47-57; No such file or directory

除了使用创建文件编写器之外，我还需要手动创建/plugin/profile/吗

stamp = datetime.now().strftime("%Y%m%d-%H%M%S")
logdir = 'logs/func/%s' % stamp
writer = tf.summary.create_file_writer(logdir)

当我尝试执行中给出的示例时，也会出现同样的错误tensorflow.org网站（https://www.tensorflow.org/tensorboard/graphs#graphs_of_tffunctions）

这是我的tensorflow简单代码：

import tensorflow as tf
from datetime import datetime

stamp = datetime.now().strftime("%Y%m%d-%H%M%S")
logdir = './logs/tensor-constants/%s' % stamp
writer = tf.summary.create_file_writer(logdir)

a = tf.constant(1, dtype=tf.int32, shape=(), name='a')
b = tf.constant(2, dtype=tf.int32, shape=(), name='b')

tf.summary.trace_on(graph=True, profiler=True)

add = tf.math.add(a,b, name='addition')

# Print will be tensornode value
print(add)

with writer.as_default():
   tf.summary.trace_export(name="tensor-constants",
        step=0,
        profiler_outdir=logdir)

同样的错误也出现在中给出的示例中tensorflow.org网站代码（https://www.tensorflow.org/tensorboard/graphs#graphs_of_tffunctions）：

from datetime import datetime
import tensorflow as tf

# The function to be traced.
@tf.function
def my_func(x, y):
  # A simple hand-rolled layer.
  return tf.nn.relu(tf.matmul(x, y))

# Set up logging.
stamp = datetime.now().strftime("%Y%m%d-%H%M%S")
logdir = 'logs/func/%s' % stamp
writer = tf.summary.create_file_writer(logdir)

# Sample data for your function.
x = tf.random.uniform((3, 3))
y = tf.random.uniform((3, 3))

# Bracket the function call with
# tf.summary.trace_on() and tf.summary.trace_export().
tf.summary.trace_on(graph=True, profiler=True)
# Call only one tf.function when tracing.
z = my_func(x, y)
with writer.as_default():
  tf.summary.trace_export(
      name="my_func_trace",
      step=0,
      profiler_outdir=logdir)

我正在使用Windows10进行开发。你知道吗
