如何使用tensorflow 2.0将图形写入tensorboard？

我正在做这个

    # eager on
    tf.summary.trace_on(graph=True, profiler=True)
    tf.summary.trace_export('stuff', step=1, profiler_outdir='output')
    # ... call train operation
    tf.summary.trace_off()

配置文件部分显示在张量板上，但还没有图表。

请找到 github gisthere https://colab.research.google.com/gist/gowthamkpr/75b703fec1b89c02b4b7644b29d2b797/untitled100.ipynb我使用 Tf2.0 创建了一个图，并在张量板上将其可视化。另外，想要了解更多信息，请浏览以下内容link https://www.tensorflow.org/tensorboard/r2/graphs.

下面提到了相同的代码：

!pip install tensorflow==2.0.0-beta1

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.
logdir = './logs/func'
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)

%load_ext tensorboard
%tensorboard --logdir ./logs/func
