Initially I downloaded two en packages using following statements in anaconda prompt.
python -m spacy download en_core_web_lg
python -m spacy download en_core_web_sm
But, I kept on getting linkage error and finally running below command helped me to establish link and solved error.
python -m spacy download en
Also make sure you to restart your runtime if working with Jupyter.
-PS : If you get linkage error try giving admin previlages.
