python - 导入 keras 和 tensorflow 时出错

Question

我使用了 from keras.layers import dot 并返回了这个错误:

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

我升级了tensorflow。也重新安装了它，但没有用。

Answer 1

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 pip install tensorflow

安装 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 作为一个软件包安装
2. Anaconda安装后，需要设置路径C:\Users\用户名\Anaconda3\Scripts
3. 更新点数
4. conda 更新
5. conda create -n tf20 python=3.7
6. pip 安装 numpy
7. pip 安装 "tensorflow>=1.15,<2.0"
8. pip install "tensorflow-gpu>=1.15,<2.0"(如果需要 GPU 支持)
9. pip install keras(安装最新的2.4.2)
10. pip install --upgrade tensorflow-hub
11. pip install keras==2.2.4(降级到2.2.4)

现在 keras 使用 tensorflow 1.15 运行也许你可以在第 9 步中执行 pip install keras==2.2.4 并删除第 11 步。在卸载所有内容之前，只需尝试从第 2 步开始的上述步骤一次。如果可行，您可以节省时间。祝你好运:)

如果这对您有用，请告诉我。
