【问题描述】：

我以前有 cuda9.0_0 和 cudnn7.1.4，我想在 gpu 中运行 tf-alpha，从这个 tf 指南：https://www.tensorflow.org/install/gpu 我发现我需要 cuDNN SDK (>= 7.4.1) 和 cuda10.so 我从控制面板卸载了以前的版本并安装了 Cuda 编译工具，发布 10.1，V10.1.105。所以，我应该成功导入 tf，但没有，我得到了错误。如果我有

    conda list cudnn

我明白了

    # packages in environment at F:\Anaconda:
    #
    # Name                    Version                   Build  Channel
    cudnn                     7.1.4                 cuda9.0_0    anaconda

虽然我安装了 cuda 10 并通过运行成功验证了 cudnn

    nvcc --version

我安装了 anaconda 并且有以前的 cuda，我之前使用过 tf 1.12.0 gpu，我的 gpu 是 nvidia 1050ti

    import tensorflow as tf

我预计它会导入 tensorflow 2.0 alpha gpu 版本

我得到的错误：

我的python版本是3.6.6

【问题讨论】：

我找到了解决办法，我在电脑上重新安装了anaconda，重新安装了CUDA并安装了10.0版本，一切正常！

标签： tensorflow anaconda cudnn tensorflow2.0

【解决方案1】：

注意：
TensorFlow 版本 >= 1.13 需要 CUDA 10.0，TensorFlow 版本
查看软件需求了解更多https://www.tensorflow.org/install/gpu#software_requirements

还需要具有 CUDA® Compute Capability 3.5 或更高版本的 NVIDIA® GPU 卡。
请参阅硬件要求以了解更多信息
https://www.tensorflow.org/install/gpu#hardware_requirements

希望这会有所帮助。
