I installed rpy2 package in a conda environment using the following command.

conda install -c r rpy2 

The installation did not give any error. However, when I try to import from the rpy2 package, it gives an error: "No module named _cffi_backend" 

from rpy2.robjects.packages import importr

How can I fix this error?

You need to install cffi to get rid of the error message. Run the following command in your conda environment, and it should fix the error.

conda install cffi
