win10下打开tensorboard报错：ValueError: Invalid format string

1. 解决错误：

利用anaconda创建新环境，并成功安装上了TensorFlow，可是当用tensorboard查看events的时候还是报错了：

Traceback (most recent call last):

看到了一个帖子：

https://stackoverflow.com/questions/54814113/invalid-format-string-tensorboard

里面提到打开TensorFlow安装的位置找到里面的：lib\site-packages\tensorboard\manager.py（我的完整路径是C:\ProgramData\Anaconda3\envs\tensorflow-gpu\Lib\site-packages\tensorboard\manager.py）

找到里面第50行：

serialize=lambda dt: int(dt.strftime("%s")),

再将小s改成大S就OK了

保存后再运行tensorboard发现不报错了

 

2. 运行tensorboard

tensorboard --logdir=路径

 

3. 修改host

在Windows的路径：C:\Windows\System32\drivers\etc下打开hosts文件

将里面的20行的注释删掉

如果国内网上不去TensorFlow官网，可以在最后加上一句：

64.233.188.121 www.tensorflow.org

 

4. 打开浏览器，输入网址：

http://localhost:6006

搞定！
