Jupyter Notebook 的 TensorFlow 给出“FutureWarning”

Question

当我在 Jupyter Notebook 中运行 Tensorflow 程序时，我得到了输出以及以下“FUTUREWARNING”。我在 Anaconda 中创建了一个 Tensorflow 环境，使用：conda create -n tf tensorflow

我还使用命令初始化了 Tensorflow 环境：conda activate

程序：

import tensorflow as tf
print ("TensorFlow version: " + tf.__version__) 

输出：

Answer 1

问题是什么？ FutureWarning 不是错误。它警告用户将来会弃用某个功能。

您看到的警告已在 GitHub 上的 tensorflow/tensorflow#30427 中报告。它们可能是良性的，但如果您想摆脱它们，一个潜在的解决方案是创建或新的 conda 环境并使用 conda 或 pip 重新安装 tensorflow。

所以要么：

conda create --name tf-env tensorflow

或

conda create --name tf-env python=3.6
conda activate tf-env
pip install --no-cache-dir tensorflow
