Cannot find python version when installing the R interface to keras - r

Question

I am trying to intsall the r interface to keras/tensoflow in R studio following the code bellow:
`install.packages('devtools')
devtools::install_github("rstudio/keras")
devtools::install_github("rstudio/tensorflow")
library(tensorflow)
install_tensorflow(version = "2.8.0")
library(keras)
install_keras()
reticulate::use_condaenv("anaconda3", required = TRUE)`
All things are Ok until install_tensorflow(version = "2.8.0"), the r studio says
No non-system installation of Python could be found. Would you like to download and install Miniconda?
I choose because I want to use the python of my our anaconda environment. But when finishing this command line, it has a warning message
Warning message:
In system2(conda, c("run", in_env, run_args, shQuote(cmd), args),:
running command '"C:/Users/jinhu/anaconda3/condabin/conda.bat"
run --prefix "C:\Users\jinhu\anaconda3" --no-capture-output "python" -c "import os;
print(os.environ['PATH'])"' had status 1
In addition, when I input the py_config function to see the available python version, it output:
Error in Sys.setenv(PATH = new_path) : wrong length for argument In addition: Warning message: In system2(conda, c("run", in_env, run_args, shQuote(cmd), args), : running command '"C:/Users/jinhu/anaconda3/condabin/conda.bat" run --prefix "C:\Users\jinhu\anaconda3\envs\r-reticulate" --no-capture-output "python" -c "import os; print(os.environ['PATH'])"' had status 1
below is my conda list:
conda_list()
name python
base C:\\Users\\jinhu\\anaconda3/python.exe

r-reticulate C:\\Users\\jinhu\\anaconda3\\envs\\r-reticulate/python.exe

Here is my conda verson:

Also when I try use_condaenv( "r-reticulate"), it shows:
`Error in Sys.setenv(PATH = new_path) : wrong length for argument In addition: Warning message: In system2(conda, c("run", in_env, run_args, shQuote(cmd), args), : running command '"C:/Users/jinhu/anaconda3/condabin/conda.bat" run --prefix "C:\Users\jinhu\anaconda3\envs\r-reticulate" --no-capture-output "python" -c "import os; print(os.environ['PATH'])"' had status 1`
I think the question is new-created r-reticulate environment cannot find the available python, what should I do to solve it?
