导入keras和tensorflow时出错

I used from keras.layers import dot并收到此错误作为回报：

ImportError: Keras requires TensorFlow 2.2 or higher. Install TensorFlow via `pip install tensorflow`

我升级了张量流。也重新安装了但没有用。

我有 CUDA 10.0 和 cuDNN 7.6.4 我也收到以下错误

ImportError：Keras 需要 TensorFlow 2.2 或更高版本。通过以下方式安装 TensorFlowpip install tensorflow

我所做的是首先卸载所有东西，比如没有 python、没有 anaconda、没有虚拟环境。

然后执行以下步骤：

1. 将 anaconda win 64 与 python 3.7 作为一个包安装
2. Anaconda安装后，需要设置路径C:\Users\username\Anaconda3\Scripts
3. 更新点
4. 康达更新
5. conda 创建-n tf20 python=3.7
6. pip安装numpy
7. pip install "tensorflow>=1.15,
8. pip install "tensorflow-gpu>=1.15,
9. pip install keras（使用最新的2.4.2安装）
10. pip install --升级tensorflow-hub
11. pip install keras==2.2.4（降级到2.2.4）

现在keras运行tensorflow 1.15 也许您可以在步骤 9 中执行 pip install keras==2.2.4 并删除步骤 11。 在卸载所有内容之前，只需尝试一次上述从步骤 2 开始的步骤。如果有效，您可以节省时间。 祝你好运 ：）

请告诉我这是否对您有用。
