I installed the allennlp package by using pip install allennlp. But when I tried to import it from Jupyter Notebook using this command from allennlp.commands.elmo import ElmoEmbedder, it gave me an error ModuleNotFoundError: No module named 'allennlp.commands.elmo'. I am wondering how should I fix this, I have the Python 3.7 installed and Spacy installed as well but for some reasons, I just cannot import the ElmoEmbedder
