AttributeError:模块“tensorboard.summary._tf.summary”没有属性“summary_scope”

Question

我尝试了本教程：使用HParams仪表板进行超参数调优，它似乎不是最新的。

我的设置：

• 木星：'0.33.12‘
• ipython：'7.2.0‘
• python：'3.6.7‘
• tensorflow：'2.0.0-dev20190426‘

我对tf.summary.scalar('accuracy', accuracy, step=1, description="The accuracy")行有个问题

我得到了这个错误，我不知道如何处理它。

Answer 1

如果您更改：!pip install -q tf-nightly-2.0-preview with !pip install -q tensorflow==2.0.0-alpha0，那么它将不带任何AttributeError运行。

Answer 2

如果你在使用Conda。尝试使用Conda运行安装这些包：

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