In general, it is recommended that Python virtual environments are created using the copies of Python installed by install_python(). For example:

library(reticulate)
version <- "3.9.12"
install_python(version)
virtualenv_create("my-environment", version = version)
use_virtualenv("my-environment")

# There is also support for a ":latest" suffix to select the latest patch release install_python("3.9:latest") # install latest patch available at python.org

# select the latest 3.9.* patch installed locally virtualenv_create("my-environment", version = "3.9:latest")
