Here you go.  It says installed successfully but then simple commands in nltk are no longer recognized.

Thanks!

Thomas,

>>> install nltk

  File "<stdin>", line 1

    install nltk

This is not how nltk is installed.

I expect nltk is already installed, from what you say, in which case you probably just need to import nltk.

Please refer to any guides on getting started with python and nltk.

That command was an error as you note.  However the problem was that I had been using nltk (following your book) successfully up to page 6, but after installing NumPy and Matplotlib in succession, I received the error messages in the attached.  After this unsuccessful attempt to install Matplotlib, nltk commands were no longer recognized.

I solved this by de-installing all 3 packages (pip3 uninstall) and then reinstalling nltk and I'm back in business.  

I will skip installation of NumPy and Matplotlib for now.

Thanks!

Indeed, from the log I can see you got a malloc error on `from nltk.book import *`, which is a clear sign that something went wrong. If you want to continue to work with NumPy, I recommend switching to anaconda, which provides a better curated experience for python and many packages (including nltk and numpy).

PS If you had included the specific command and error in your email instead of attaching a file with your entire session, you could have gotten support sooner. I recommend doing so in the future: less work for those trying to help you, better results for yourself.
