当我在Conda环境中尝试使用Keras时，出现以下错误：
pr_curve_pb = _pr_curve_summary.pb attributeerror: 'module' object has no attribute 'pb'
错误痕迹：

我试图再次卸载并安装，但是没有用。
我有一个非常类似的错误：

pr_curve_pb = _pr_curve_summary.pb
AttributeError: 'module' object has no attribute 'pb'
这是GitHub CI工作流中的Python 2.7和TF 1.15.0 。
在搜索此异常时，我在这里找到了这篇文章，也是这样：AttributeError: module 'tensorboard.plugins.pr_curve.summary' has no attribute 'pb'
这链接到该注释，该注释建议pip uninstall tensorflow-tensorboard，因为有旧的软件包tensorflow-tensorboard和新的软件包tensorboard，这可能会使它混乱。
就我而言，这无济于事（我tensorflow-tensorboard没有安装但没有安装的异常tensorboard），尽管该软件包tensorboard存在于中~/.local/lib/python2.7/site-packages。
对我有用的解决方案很简单：
rm -rf ~/.local/lib/python2.7/site-packages/tensorboard*
然后安装新的TF（pip install --user tensorflow==1.15.0）。
