无法导入Tensorflow 2（PyCharm）

Question

我无法在PyCharm中导入TF2。我使用reh requirements.txt安装了它，并尝试了不同的版本（最新版本和2.0.0）。但是，当我要导入它时，出现以下错误：

Traceback (most recent call last):

我拥有Windows 10和PyCharm的最新版本。我使用Python 3.6，没有GPU，但我的CPU支持AVX。此外，我发现此解决方案无法解决问题：

import os
os.environ['CUDA_VISIBLE_DEVICES'] = '-1'

它对我有用。我在PyCharm中创建了一个新项目（尽管使用Python 3.7），添加了TensorFlow 2.1.0，并使用左侧窗格的https://www.tensorflow.org/overview/]运行了演示文件。
