Thank you for contacting us.
I believe you’re not using the latest Edison image. To check if you’re using the latest image you can type cat /etc/version and you should receive 201606061707 as an output. The link to download the latest Edison image can be found here https://software.intel.com/en-us/iot/hardware/edison/downloads .
Between different images, there’s not many different features that would make one better at building robots, machine learning etc. All images come with a predetermined functionality and doesn’t differ much one from the other in terms of the features you need. If there’s something extra you need to add to the image you can add it and build your own image. For this, I’d suggest you to look at the Edison BSP: http://www.intel.com/content/www/us/en/support/boards-and-kits/000005616.html .
Now, with the new image installed, try to install NLTK again and let us know if you’re successful. You can try with the instructions from http://www.nltk.org/install.html .
We’ll be waiting for your response.
We’ll try to help you out in any way we can. I tried to install NLTK using the guide I posted above and using the latest image and didn’t see any issues.
Run the following commands:
Cat /etc/version (you should see 201606061707 as an output. Please confirm this is what you receive)
pip install -U nltk
pip install -U numpy
This were the commands I used to install NLTK. Give it a try and let us know your results.
