Hi,

I'm trying to run a Jupyter notebook that uses r libraries. this is the error message:

<module>
     14 import itertools
     15 from datetime import datetime

     17 import rpy2.rlike.container as rlc
     18

     45 if sys.platform == 'win32':

     31 
     32 R_HOME = get_r_home()

    347         if handle is None:
--> 348             self._handle = _dlopen(self._name, mode)
    349         else:
    350             self._handle = handle

OSError: [WinError 127] The specified procedure could not be found

 I also tried to open R notebook through Jupyter Lab, but all I have there is a python notebook.

Thank you Dan, I followed the instructions in your links without any result, then I started from scratch in a different machine (with r 4.0.0 instead of 4.0.3) and it works. I just followed these steps: 

  1. Install R (CRAN). 
  2. Set up R-ArcGIS Bridge using the geoprocessing tab in the Options dialog box.
  3. Install the package space-time-learn-lesson using the Python Package Manager in Pro.
