r - Windows 10 中 R 中的 TensorFlow 安装

Question

我正在尝试为 R 安装 keras 和 tensorflow。但是，我收到一条警告消息和一条错误消息。我按照https://tensorflow.rstudio.com/installation/提供的说明进行操作。我还下载了 Anaconda3 并更新conda到最新版本 4.8.5。我在 Windows 10 笔记本电脑上本地使用最新版本的 R（版本 4.0.2）和 RStudio（版本 1.3.1093）。

我还查看了 Stack Overflow 上的相关线程并遵循他们的建议，包括卸载和重新安装 R、RStudio 和 Anaconda，以及安装 Python（版本 4.8.5）。

1. 为什么即使我已经将 conda 更新到最新版本，我也会收到更新 conda 的警告消息？
2. 为什么运行后“安装完成”install_tensorflow()但我得到“错误：找不到TensorFlow的安装”。我什么时候跑tf$constant("Hello")？
3. 我该如何解决这些问题？

> library(keras)
> library(tensorflow)
> install_tensorflow()
