I tried to resolve the issue by trying out solutions suggested in other threads with this same issue. I also opened an issue under tensorflow's master repo as well (tensorflow/tensorflow#21413 (comment)), but the person helping me redirected me to here. The following is from my terminal. I am running virtualenv and I am running Python 2.
tensorflow) hkaushal-mac01:~ hkaushal$ pip install tensorflow_fold-0.0.1-cp27-cp27mu-manylinux1_x86_64.whl
tensorflow_fold-0.0.1-cp27-cp27mu-manylinux1_x86_64.whl is not a supported wheel on this platform.
