验证正确安装 tensorflow 时出错

Question

通过本指南安装 tensorflow - https://github.com/jeffheaton/t81_558_deep_learning/blob/master/t81_558_class_01_1_overview.ipynb - 我收到一个我不明白的错误。我可以进入然后我激活 tf 并得到提示。

安装后，我运行以下代码来验证安装：

import sys

    import tensorflow.keras
    import pandas as pd
    import sklearn as sk
    import tensorflow as tf

    print(f"Tensor Flow Version: {tf.__version__}")
    print(f"Keras Version: {tensorflow.keras.__version__}")
    print()
    print(f"Python {sys.version}")
    print(f"Pandas {pd.__version__}")
    print(f"Scikit-Learn {sk.__version__}")
    print("GPU is", "available" if tf.test.is_gpu_available() else "NOT AVAILABLE")

这是我得到的错误：

这些是我安装的包：

pip install --exists-action i --upgrade sklearn
pip install --exists-action i --upgrade pandas
pip install --exists-action i --upgrade pandas-datareader
pip install --exists-action i --upgrade matplotlib
pip install --exists-action i --upgrade pillow
pip install --exists-action i --upgrade tqdm
pip install --exists-action i --upgrade requests
pip install --exists-action i --upgrade h5py
pip install --exists-action i --upgrade pyyaml
pip install --exists-action i --upgrade tensorflow_hub
pip install --exists-action i --upgrade bayesian-optimization
pip install --exists-action i --upgrade spacy
pip install --exists-action i --upgrade gensim
pip install --exists-action i --upgrade flask
pip install --exists-action i --upgrade boto3
pip install --exists-action i --upgrade gym
pip install --exists-action i --upgrade tensorflow==2.0.0-beta1
pip install --exists-action i --upgrade keras-rl2 --user

作为一个菜鸟，我尝试用谷歌搜索错误，但我遇到的每个安装错误都与我的不同。

安装是通过 Juypter 在 3.6 内核上进行的。所有软件包都安装正确，但由于某种原因，验证安装会产生错误。

编辑：对不起，我忘了包含代码！

Answer 1

在我的笔记本电脑上安装 tf 太让人头疼了。

解决方案： AWS EC2 Ubuntu 18.04（免费套餐），安装 Tensorflow，在本地使用 VS Code 进行远程开发。

我学到了很多在 Linux 上设置 tf 的知识。

Answer 2

我当前的安装是一团糟。我安装了几个 ide，然后是 python。路径一团糟，要进行故障排除非常痛苦。

我从一个全新的操作系统安装开始，并且以正确的方式进行操作。

Answer 3

安装 tensorflow 可能会很痛苦，尤其是在您需要 GPU 支持的情况下。幸运的是，它最近变得更容易了，而且比该指南看起来要容易得多。

这一行应该安装正确版本的 tensorflow-gpu、keras 以及相应的 cuda 和 cudnn 工具包：

conda install -c anaconda keras-gpu

如果你还没有，我会试一试，因为它应该只需要几分钟
