使用Tensorboard的奇怪报错解决

(tf2-gpu) PS D:\11_Graduation_Project\04_code\Experiment01> tensorboard --logdir logs/fit
Traceback (most recent call last):

最后的 ValueError: Not a TBLoader or TBPlugin subclass:

在tensorflow的backend中看到，引发这个错误是因为传入make_plugin_loader()函数的plugin_spec不是TBloader也不是TBplugin，不想往下找原因了，再找要到源码里了，毕竟只是个工具，我觉得重装一下就好了。

我使用 conda list 查看了一下安装包，发现tensorboard和tensorflow的安装channal不同，应该是我安装了多个版本的tensorboard，我觉得tensorborad-plugin-wit是元凶，所以我就使用 pip uninstall tensorboard 和 pip uninstall tensorboard-plugin-wit 最后竟然work了!!!
