R reticulate unable to find installed python library

On a whim I downloaded and installed the latest RStudio desktop (1.2.701) and upgraded from 1.1.442. This seems to have solved my issue. The packages load and I now see that when I run py_config I see paths that reflect my environment choice, as I would expect.

> py_config()
python:         C:\Users\jal\AppData\Local\Continuum\Anaconda\envs\r-reticulate\python.exe
libpython:      C:/Users/jal/AppData/Local/Continuum/Anaconda/envs/r-reticulate/python36.dll

I solved my issue by following this way in RStudio:

py_config() No non-system installation of Python could be found. Would you like to download and install Miniconda? Miniconda is an open source environment management system for Python. See https://docs.conda.io/en/latest/miniconda.html for more details.
