Can't import NLTK into Jupyter Notebook

Question

I'm pretty new to python, Jupyter notebook, Tensorflow, and that whole lot in general. I'm getting started with a machine learning project. I've gotten to the point where I want to import "nltk" into my thing. It doesn't work. I've installed nltk with pip, and conda, and everything, in my terminal. When I do it again in the notebook, it says I've already installed it, which is correct. But when I try to import it it gives me a ModuleNotFoundError :

I'm on a macbook, by the way. Any help?

Going forward you can follow these steps (through terminal) so that same issues don't crop up again.

1. Create a conda environment if it's not already done

   conda create -n py3_env python=3.8

2. Get into the conda environment

   conda activate py3_env

3. Install ipykernel

   conda install ipykernel

4. Link the kernel to this conda env

   ipython kernel install --user --name=py3_env

5. Deactivate the conda environment

   conda deactivate

Now, when you open jupyter, you can select this kernel from the dropdown menu kernel >> Change kernel . Now, all the packages you've installed in this conda environment would be available in jupyter as well. Eg you can install nltk in this environment in the following way:

conda activate py3_env
pip install nltk
conda deactivate
