Jupyter Notebook: Importing SMOTE from imblearn - ImportError: cannot import name 'pairwise_distances_chunked'
I have encountered a similar problem. I could solve by opening a new IPython console.
I know it's a bit late, but for anyone using Jupyter notebook, I could solve my problem by just restarting the kernel.
