R中tensorflow的Sys.setenv

在运行CNN模型之前，我运行以下代码行。我写的5行Sys.setenv（）行可以吗？我真的不确定

如果我想在R.environ文件中复制它，我需要直接通过它还是需要更改表单

library(usethis)
library(devtools)
library(reticulate)
library(hdf5r)
Sys.setenv(PATH = paste(Sys.getenv('PATH'), "C:/Users/PC/AppData/Local/r-miniconda/envs/r-reticulate/", sep = ';'))
Sys.setenv(PATH = paste(Sys.getenv('PATH'), "C:/Users/PC/AppData/Local/r-miniconda/envs/r-reticulate/Scripts", sep = ';'))
Sys.setenv(PATH = paste(Sys.getenv('PATH'), "C:/Users/PC/AppData/Local/r-miniconda/envs/r-reticulate/Lib/site-packages/h5py", sep = ';'))
Sys.setenv(PATH = paste(Sys.getenv('PATH'), "C:/Users/PC/AppData/Local/r-miniconda/Scripts", sep = ';'))
Sys.setenv(PATH = paste(Sys.getenv('PATH'), "C:/Users/PC/AppData/Local/r-miniconda/envs/r-reticulate/Lib/site-packages/tensorflow", sep = ';'))
use_condaenv("r-reticulate", required = TRUE)
library(tensorflow)
library(keras)
