Conda、Tensorflow 和 Keras 版本不匹配问题

Question

当我尝试在我的 Conda 环境中使用 Keras 时出现此错误：

pr_curve_pb = _pr_curve_summary.pb attributeerror: 'module' object has no attribute 'pb'

错误痕迹：

我尝试卸载并重新安装，但没有成功。

我找到了解决办法：

尝试使用 Conda 安装这些包运行

    conda install -c anaconda tensorflow-gpu 
    
    conda install -c anaconda keras

Answer 2

我在最近 conda update --all 之后尝试导入 kerastuner（它也导入 tensorflow）时出现上述错误（conda 不允许我安装 keras-tuner 直到我更新了所有包）。从 github 那里得到 this 很好的建议，它解决了我的问题：

conda remove tensorflow
conda install tensorflow-estimator=2.1
conda install tensorflow-gpu=2.1

如果你重新安装了kerastuner before doing the above, it will no longer be installed. So you will need to follow the [instructions][2] to install kerastuner`（目前推荐的方法之一如下）：

我遇到了一个非常相似的错误：

Traceback (most recent call last):

  File "/home/runner/.local/lib/python2.7/site-packages/tensorflow/__init__.py", line 99, in <module>

    pr_curve_pb = _pr_curve_summary.pb
AttributeError: 'module' object has no attribute 'pb'

这是 Python 2.7 和 TF 1.15.0，在 GitHub CI workflow.

在搜索这个异常时，我在这里找到了这个post，而且 this: AttributeError: module 'tensorboard.plugins.pr_curve.summary' has no attribute 'pb'

这链接到 this comment，建议 pip uninstall tensorflow-tensorboard，因为有旧包 tensorflow-tensorboard 和新包 tensorboard，这可能会弄乱它向上。

在我的例子中，这没有帮助（我得到一个例外，即 tensorflow-tensorboard 没有安装，但 tensorboard 也没有安装），尽管包 tensorboard 存在于 ~/.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*

然后再安装新的 TF (pip install --user tensorflow==1.15.0)。
