Hello !

I want to try using NupiC.Studio . I create one sensor and give him csv-file. I got errors:
File “/home/sergey/.local/lib/python2.7/site-packages/nupic/data/”, line 385, in getNextRecord
IndexError: list index out of range.
I can download my project and csv-file.
Can we help me?

Thanx a lot,


I don’t think NuPIC Studio has been an active project for a couple of years. (cc @david-ragazzi)


4 posts were split to a new topic: Problems with NuPIC input data file format


I changed the flag from T to S. But I get the same errors.


I can’t tell if this is a nupic problem or a problem. Can you show your code?


I want to develop the small example in and run it:
The code below is automatically generated by NuPIC Studio and aims to help you to quickly integrate
this HTM network into your application using the NuPIC Network API.
For use, this code, just create a new Python file and copy/paste these lines into it. Run it and voila!

I attached 2 photos:
One of them is my csv-file and the second is errors ,which I got,when I tried to run this project.



Your data file still looks wrong. The flags header has two fields, but everywhere else there is only one? How many fields are you trying to process?


In this stage only one field I can try to process. Do you know how to change this field? Because I tried to process when I had one field. And I got same errors.


To be clear, I have not used NuPIC Studio in a few years. I don’t think it is going to work with the latest version of NuPIC. And even if you do get it working with an older version, I don’t think I can help you because I didn’t work on the code and the project seems to be unmaintained.

What are you trying to do with NuPIC? Also, why did you decide to use NuPIC Studio?


We want to visualise our results to make easier our network parameters tuning


I mean it looks like you’re trying to do NLP but each row is going to be encoded as one string field. I don’t think that’s what you want. Be sure to read the NuPIC API docs to see some examples.
