'RPY2 - Security issue running on osx-arm64 (M1): Cannot allocate write+execute memory for ffi.callback()

For any one encountering this problem on Mac M1, where rpy2 is not working, try compile from source while setting RPY2_CFFI_MODE=API. If this fails due to some clang compilation errors, you can still use the traditional conda install method conda install rpy2. In my case pip3 was not installing all required dependencies. Conda does!

conda install rpy2

python r
