安裝 Tensorflow 的問題

Question

我在安裝 Tensorflow 時遇到問題

我剛剛完成安裝 Tensorflow

$ pip install --user --upgrade tensorflow

這些是我在安裝后得到的最后幾行

Successfully built absl-py gast
Installing collected packages: wheel, six, grpcio, absl-py, numpy, gast, astor, tensorflow, h5py, werkzeug, se                           tuptools
Successfully installed absl-py-0.7.1 astor-0.8.0 gast-0.2.2 grpcio-1.21.1 h5py-2.9.0 numpy-1.16.4 setuptools-4                           1.0.1 six-1.12.0 tensorflow-1.13.1 werkzeug-0.15.4 wheel-0.33.4  `````

然后當我輸入以下命令時：

$ pip install --upgrade tensorflow

根據以下內容，我確實收到了一些requirement already up-to-date的requirement already up-to-date 。

我將其解釋為一切都已安裝和升級（我在這里錯了嗎？）

現在我的問題是，當我嘗試在 Jupyter notebook 中導入 Tensorflow 時，我收到以下錯誤消息

ImportError: Traceback (most recent call last):

知道可能是什么原因以及我需要更改什么才能啟動和運行 tensorflow 嗎？

提前感謝大家對上述問題的任何幫助。

Answer 1

我通過使用以下命令將 tensorflow 降級到 2.0 版解決了這個問題：

點安裝張量流==2.0

然后像這樣使用：

從 tensorflow.keras.applications 導入 vgg19 從 tensorflow.keras.models 導入 load_model

我希望它有幫助。
