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

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.

ModuleNotFoundError                       Traceback (most recent call last)

During handling of the above exception, another exception occurred:

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 
    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
