ModuleNotFoundError: 没有名为“ntlk”的模块

Question

I am using PyCharm and Anaconda. I have installed NTLK with sudo pip install -U nltk and even to make sure since I'm on Mac OS and I saw this previous SO post to also try pip3 install nltk .

However, no matter where I try (PyCharm's terminal, Pycharm's Python, or my own terminal), I cannot get import ntlk to work and always get ModuleNotFoundError: No module named 'ntlk' .

The weird thing is that I actually manage to run some code with a simple "Python test.py" that contains: from nltk.tag import StanfordPOSTagger but whenever I try to import ntlk to be able to then nltk.download('punkt') I get the No module named 'ntlk' error.

Would you know where that is coming from?

Edit:

output of

1. python -V: Python 3.7.0
2. python3 -V: Python 3.7.0
3. pip -V: pip 18.0 from /Users/.../lib/python3.7/site-packages/pip (python 3.7)
4. pip3 -V: pip 18.0 from /Users/.../lib/python3.7/site-packages/pip (python 3.7)

As for python3 -c "import ntlk; print('ntlk available')" it returns:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'ntlk'

Edit 2:

Output of python -c "import os, sys; print(os.linesep.join(sys.path))"

Answer 1

You have a typo in your import code.

It's NLTK (ie import nltk ) not ntlk =)
