安装Tensorflow时出现的问题

Question

我在安装Tensorflow时遇到问题

我刚刚用以下命令安装了Tensorflow

$ pip install --user --upgrade tensorflow

这是我在安装后得到的最后几行代码

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  `````

然后当我输入以下命令时：

$ pip install --upgrade tensorflow

我确实得到了一堆requirement already up-to-date，如下所示。

我将其解释为所有内容都已安装和升级(我说错了吗？)

现在我的问题是，当我尝试在Jupyter notebook中导入Tensorflow let时，我得到了以下错误消息

ImportError: Traceback (most recent call last):

Failed to load the native TensorFlow runtime.

你知道原因是什么吗?我需要改变什么才能让tensorflow启动并运行？

提前感谢大家对上述问题的任何帮助。

我已经解决了这个问题，通过使用以下命令将tensorflow降级到2.0版本：

pip安装tensorflow==2.0

然后像这样使用：

从tensorflow.keras.applications导入vgg19从tensorflow.keras.models导入load_model

我希望它能帮上忙。
