is there way both running? rpy2 runs in ipython guess there installation shoiuld correct. thanks, marv

there more differences between environment ipython called , 1 notebook called: error der angegebene pfadname ist ungültig occurs while trying r shared library.

you'd need tell little more how start either ipython or notebook.

having said, should note rpy2 working better on linux or os x. if ipython notebook primary interest, running through docker container solution.
