将 tensorflow 从 2.1.2 升级到 2.3.0 后，Tensorboard 无法使用

【中文标题】将 tensorflow 从 2.1.2 升级到 2.3.0 后，Tensorboard 无法使用【英文标题】：Tensorboard not working with after upgrading tensorflow from 2.1.2 to 2.3.0 【发布时间】：2021-05-19 01:43:00 【问题描述】：我使用的是 TensorFlow 2.1.2 和 TensorBoard 2.4.1，
import os, shutil
import tensorflow as tf
print(tf.__version__)
SUMMARY_DIR = 'summary/testing_this'
if 1:
# SUMMARY_DIR is the path of the directory where the tensorboard SummaryWriter files are written
# the directory is removed, if it already exists
if os.path.exists(SUMMARY_DIR):
shutil.rmtree(SUMMARY_DIR)
train_summary_writer = tf.summary.create_file_writer(os.path.join(SUMMARY_DIR, 'train'))
test_summary_writer = tf.summary.create_file_writer(os.path.join(SUMMARY_DIR, 'test'))
train_summary_counter = 0
for i in range(100):
with train_summary_writer.as_default():
tf.summary.scalar('train/sampled-softmax loss', i+5, step=train_summary_counter)
train_summary_counter += 1
上面编写的代码运行良好。但是当我升级到 TensorFlow 2.3.0 时，抛出了以下错误-
Serving TensorBoard on localhost; to expose to the network, use a proxy or pass --bind_all

有人可以帮我用 tf 2.3.0 运行 tensorboard 吗？
【问题讨论】：
【参考方案1】：使用pip install 'tensorboard<2.4' 降级为我解决了这个问题。
似乎 tensorboard 2.4 做出了一些重大改变。
【讨论】：
可能与github.com/chaoleili/jupyterlab_tensorboard/issues/25有关以上是关于将 tensorflow 从 2.1.2 升级到 2.3.0 后，Tensorboard 无法使用的主要内容，如果未能解决你的问题，请参考以下文章
