Setting and Running Python with Reticulate Package in RStudio for Windows OS

In this video, I will walk through steps to set up a python environment in a RStudio project directory. I used the Windows 10 OS.
#python , #RStudio , #reticulate

Steps:
1. PREREQUISITE - anaconda ready, correct path to python in Windows PATH
2. TEST WINDOW AND PYTHON CONNECTION
3. CREATE NEW RSTUDIO PROJECT
4. INSTALL VIRTUALENV
5. CREATE A NEW ENV
6. ACTIVATE ENV
7. INSTALL PYTHON LIBRARIES
8. Create .Rprofile file

A comment from Dr David Hopp (Thanks Dr Hopp) below:

It turns out that even after following your directions I still had a problem. It was with the PATH variable, that left-over from thirty-five years ago. My problem with the local PATH was two-fold. First, I had done some python/miniconda installs, which I uninstalled, but good old PATH still had pointers to python, and when Windows couldn't find that folder, it defaulted to offer the python app from Windows Store. I got rid of that (after hunting it down) and then trying to run pip didn't work (stackexchange helped with that in some old questions). I had the path to miniconda3 in my PATH but I had to add others too as per C:\Users\cassi\miniconda3; C:\Users\cassi\miniconda3\Scripts;
C:\Users\cassi\miniconda3\Library\bin

That was a critical step. Every once in a while there is a rumor that MS will get rid of PATH, but it hasn't happened yet. If you have the opportunity to add these PATH suggestions as a note it might help others save time. Once again, please accept my gratitude for your video.

All was going well until 15:19. The moment I reconfigured, the R session aborted due to a fatal error. The session was terminated. This happens each time.

Sorry, this might be a late comment.. Do i have to install the libraries each time i start a new project ?

Mr. Kim. Tons of thanks! I was able to get reticulate and the python environment functioning. Before, I was simply attempting to call python in reticulate. Failed. Your presentation was just what I was looking for. Plus, I got to play with an old friend - MS DOS. (Maybe it's not called that anymore).

Virtual environment created through Anaconda CMD, and I can see the .env folder in my R project. But I am not able to activate this environment through Anaconda CMD

I have still got a problems with running code chunks (Session Abort). It's my 100 attempt to make it work. What I've tried already is: installing github version; installing different conda environments; reinstalling Rcpp; updating R and Rstudio; setting different environment paths and few more. If someone coped with similar problems, please let me know.

Error: Your current architecture is 64bit; however, this version of Python was compiled for 32bit.
Use if you'd like to install a Miniconda Python environment.
