Tensorboard原本是Google TensorFlow的可视化工具，可以用于记录训练数据、评估数据、网络结构、图像等，并且可以在web上展示，对于观察神经网络的过程非常有帮助。

项目场景：

突然报如下错误，我以为是环境坏掉了，重装环境搞了半天，猜猜最后是什么原因？

ImportError: TensorBoard logging requires TensorBoard with Python summary writer installed.

问题描述

ModuleNotFoundError                       Traceback (most recent call last)

During handling of the above exception, another exception occurred:

      6 from .writer import FileWriter, SummaryWriter  # noqa F401

ImportError: TensorBoard logging requires TensorBoard with Python summary writer installed. This should be available in 1.14 or above.

原因分析：

tensorboard的版本太低了
使用下面的版本安装新版本的tensorboard

解决方案：

如果还报有没有No module named ‘tensorboard’ 的错,则说明是由于没有安装tensorboard引起的,类似一下这种报错

Traceback (most recent call last):
  File "/home/../anaconda3/envs/pytorch/lib/python3.7/site-packages/torch/utils/tensorboard/__init__.py", line 2, in <module>
    from tensorboard.summary.writer.record_writer import RecordWriter  # noqa F401
ModuleNotFoundError: No module named 'tensorboard'

所以解决办法是安装tensorboard即可

 如果确认安装了tensorboard 依然报错,应该和版本有关

安装新版本的tensorboard

conda install -c conda-forge tensorboard

可能存在的问题：

报错：TypeError: __init__() got an unexpected keyword argument 'serialized_options'

# 很可能是protobuf的版本不对导致的
# 可以先卸载掉protobuf，再重新安装

pip install -U protobuf
