I have a problem with Tensorflow installation in R (I use RStudio-1.3.1073) where the old Python version 3.6 is installed. I would like 3.7. How to change it ?

Here the step I used:

I download Tensorflow in R and I got tensorflow_2.2.0.zip using:

```
> install.packages("tensorflow")
```

Then I install Tensorflow and in r-reticulate folder I got Python 3.6 as detailled:

```
> install_tensorflow()
## Package Plan ##
environment location: C:\Users\PC\AppData\Local\r-miniconda\envs\r-reticulate
added / updated specs:
- numpy
- python=3.6
```
