我在安装 tensorflow、keras 和 pytorch 方面需要帮助答案

【问题描述】：

当我导入 Tensorflow、Keras 或 Pytorch 时，我会遇到以下错误：

我使用的是 Window 10，并且我的 CPU 支持 AVX。我还在 Python(Anaconda) 上准备我的项目，并使用pip(pip install keras) 和Pytorch 使用conda 安装Keras、TensorFlow 和Pytorch

我在下载前激活了我的虚拟环境(Test_01)，下载后我用conda list再次检查了它。
检查这 3 个程序是否已安装后，我在 Anaconda 提示符下使用 ipython 导入它们。这就是我所面临的：

Keras 错误信息说：

Keras 需要 TensorFlow 2.2 或更高版本。通过安装 TensorFlow 点安装TensorFlow

另外，tensorflow 和 pytorch 说

ModuleNotFoundError: No module named 'tensorflow'

ModuleNotFoundError: No module named 'torch'

所以我再次安装了TensorFlow 和pip，它说：

ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

===============================================================================

我保证我检查过我在相同的环境（Test_01）上安装并执行了它们，所以你能告诉我：我该怎么办？以及如何检查我的“CUDA”版本？我在 cmd 上使用 'nvxx --version' 进行了尝试，但没有任何效果

【问题讨论】：

我不知道如何发布超过 1 张图片，所以我只上传了一张。如果您需要更多屏幕截图，请告诉我如何上传。
请不要张贴图片来呈现文字。您应该包含完整的错误，这不是完整的错误消息，pip 的整个输出应该可以工作。
这不仅仅是建议，我的第二点将帮助人们回答您的问题，因为部分错误消息并不是真正有用。
我根据提示更新了错误消息。
我用 === 行覆盖它们，以便用我的解释来区分它们......

首先，我要感谢大家在我的帖子中发表评论。我发现没有安装visual studio c++，所以我把它安装到了我的labtop。你可以在这里找到它 https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
