我在Anaconda环境中的Windows 10 Pro上安装了Tensorflow。当我尝试使用tf.summary API时，我系统地得到AttributeError:
python --version
Python 3.8.12
python
>>> import tensorflow as tf

根据文档，image和scalar是TF2.8中tf.summary的属性。此错误是否与Windows有关？我使用Anaconda来管理我的环境，但TF是用PIP安装的。
我通过强制重新安装tensorboard解决了这个问题：
pip install --force --no-deps tensorboard
在那之后，一切都很顺利。
