**Other Information:**
- OS: Windows10
- Python Version 3.7.2
- VSCode Version 1.53.2
- ARPEL Version v2.0.1

**Additional context**
- python.pythonPath is set to "C:\\Users\\\\.virtualenvs\\Test_Project-Sy3-GYB1\\Scripts\\python.exe"
- I also tried setting AREPL.pythonPath to the same path, did not change anything
- When python for ARPEL is set to system python it works. However, modules can not be found as they are only in pipenv
