Hi @kylec1729,
Use the following to check that R can find Python, and that the Python package (here pandas) can be found and is available:
# Had to run this on command line first to install Python package
# py -3.7 pip install pandas
py_available(initialize=TRUE)
py_available()
py_discover_config() # ??Need this after each new Python package install
py_config()
py_module_available("pandas")
Also, remember that Python needs directories specified with "forward_slash" separators, not double "backslash" as R may use. My experience is on Windows 10, 64 bit.
