在 Jupyter 中导入 Tensorflow 的问题。 DLL 加载失败。指定模块加载失败

Question

我打开了一个 Jupyter notebook 并尝试将 tensorflow 导入为 tf 并收到以下错误消息

import tensorflow as tf

这是我收到的消息

--> 342         return _load(spec)
    343 

ImportError: DLL load failed: The specified module could not be found.

During handling of the above exception, another exception occurred:

我尝试使用以下命令安装它

# install pip in the virtual environment
  conda install pip
# install Tensorflow CPU version
  pip3 install --upgrade tensorflow # for python 3.*
# install Keras (Note: please install TensorFlow first)
  pip install Keras

但我仍然收到相同的错误消息。如果有帮助，我正在使用 windows 10。

哦，我还通过

检查了我的命令行，看看它是否在 python 中工作

python
>>> import tensorflow as tf

但我仍然收到相同的错误消息

这个问题应该可以通过安装
Microsoft Visual C++ Redistributable for Visual Studio 2019.
