在 R 中運行 Keras 順序 model

Question

我正在創建一個神經網絡 model，我想在 R Studio 中運行keras_sequential_model() 。 我已經使用install_tensorflow()命令安裝了張量流。 但是，當我運行keras_sequential_model()來構建我的 model 時，它會返回一個全局環境，而不是我可以編譯的 model。 我在控制台中打印了以下內容：

如何解釋這一點以及我做錯了什么？

老實說，我在 ML 任務中使用了 python，建議您嘗試一下。 至於您的問題，我建議您查看此示例https://tensorflow.rstudio.com/guide/keras/ ，因為逐步說明了如何操作。 此外，嘗試使用 google colab，因為這可能是您的桌面問題，而不是您的代碼。
