How to update Python version in r-reticulate for TensorFlow under R

I installed TensorFlow 2.2.0, Keras 2.3.0 and Reticulate 1.16 under R.

But I have still this error when I use TensorFlow: Error: Installation of TensorFlow not found. I believe it is from Python 3.6 installed with TensorFlow. How to update Python version in r-reticulate?

Python environments searched for 'tensorflow' package:
 C:\Users\Mezeix\AppData\Local\r-miniconda\envs\r-reticulate\python.exe

You can install TensorFlow using the install_tensorflow() function.

install_tensorflow()#missed step

library(tensorflow)

Try:

library(tensorflow)

install_tensorflow()

Then:

library(tensorflow)

tf$constant("Hellow Tensorflow")

work?
