运行时tensorboard --logdir log_dir出现错误：

这个问题可能是什么原因？

Answer 1

如果您的系统中安装了两个版本的 tensorboard，则需要卸载其中之一。

我被困了几个小时，但我最终使用以下方法修复了它：

像魅力一样工作：https : //github.com/pytorch/pytorch/issues/22676

pip uninstall tb-nightly tensorboardX tensorboard
pip install tensorboard

Answer 2

安装 tensorflow==2.0.0-rc2 后我遇到了同样的问题。卸载 tensorboard 没有帮助。

在我的案例中的罪魁祸首是 tb-nightly 包：

#python3.7 -m pip list | grep tb
tb-nightly           1.15.0a20190806

卸载包并重新安装TensorFlow后，tensorboard开始正常工作。

当我有两个版本的张量板时，我遇到了同样的错误。在我的Tensorflow 2.0环境中，除了核心Tensorflow库之外，我还可以看到从TF 1.14版本安装的其他库。

做一个pip list，看看那里有哪些版本的tensorflow库。在我的系统中

...
tensorboard                   1.14.0              
tensorflow-estimator          1.14.0              
tensorflow-gpu                2.0.0rc0            
tensorflow-serving-api        1.14.0              
termcolor                     1.1.0               
tf-estimator-nightly          1.14.0.dev2019080601
...

这是我所做的：

pip uninstall tensorboard
pip install --force-reinstall tf-nightly-2.0-preview

Answer 4

tensorboard如果显示系统上安装了两个，请运行以下代码，删除一个。

import pkg_resources

for entry_point in pkg_resources.iter_entry_points('tensorboard_plugins'):
    print(entry_point.dist)
