使用venv python 為R 安裝tensorflow？

Question

我想為 R 安裝 tensorflow（和 Keras）。
我用了那些台詞

install.packages("keras")
install.packages("tensorflow")

library(keras)
library(tensorflow)

現在我想做：

install_tensorflow()
install_keras()

但是我的 python 環境不一致。 有沒有辦法告訴 R 尋找虛擬 python 環境？

謝謝

編輯：這是告訴我我的環境不一致的錯誤。

謝謝@TFer，我之前嘗試“virtualen”方法時錯過了envname參數。

解決方案只是通過在 function 中傳遞這些選項來創建一個新的虛擬環境：

install_tensorflow(method="virtualenv", envname="venv-R")
