Hotgym, running run.py, Typeerror

[domisoxz]

After running run.py I got the following error:

File"home/domiso/.local/lib/python2.7/site-packages/nupic/frameworks/opf/modelfactory.py",line 70, in create if modelConfig['model']="CLA": TypeError:'NoneType' object has no attribute 'getitem'

How to solve it?

Hi, you must be Claire from YouTube? Please answer a couple questions for me:

• What OS are you using?
• How did you install NuPIC?

Hi Matt,

Yes. I am using ubuntu 16.04 64 bit. I installed NUPIC using the following command from your website:

pip install https://s3-us-west-2.amazonaws.com/artifacts.numenta.org/numenta/nupic.core/releases/nupic.bindings/nupic.bindings-0.4.2-cp27-none-linux_x86_64.whl pip install nupic

I have run the test.py after installation and no error was reported. I have also run the swarm.py and it worked.

I have been following your youtube video and I am now with running the run.py and that's when I run into this problems.

Is it because in the modelfactory.py line 69 it assigns ModelClass = None and in the following lines, it tries to assign an value to ModelClass based on the modelConfig info? How can I solve it?

Thanks, Claire

I have not tried installing NuPIC on Ubuntu 16 yet. Can you tell me what version of python it uses?

python --version

I have the same problem with Python 2.7.10. I am on Mac OS 10.12.4 (16E195)

@MedSolve Please tell me:

• what command you are running from the source code
• what version of nupic you have installed
• what version of the source code you have (git rev-parse HEAD if using git, otherwise what version of the source code you downloaded)

This is the versions i am not sure about the source code version since i set up "my own" code here

• nupic: 0.7.0.dev0
• nupic.bindings==0.6.1
• Python 2.7.10
• Mac OS 10.12.4 (16E195)

The error: File "/Users/mrmusling/Desktop/htm-ecg/nupic/implementation.py", line 140, in predic infer=True File "/Library/Python/2.7/site-packages/nupic/bindings/algorithms.py", line 2906, in c ompute if type(classification["actValue"]) in (int, float): TypeError: 'NoneType' object has no attribute '__getitem__'

This is the parts of the source code. The variables recordNum and patternNZ is elsewhere so i just left them out. I have already trained my classifier that part is left out too.

classifier = SDRClassifierFactory.create()

result = classifier.compute(
            recordNum=recordNum,
            patternNZ=patternNZ,
            classification=None,
            learn=False,
            infer=True
)

After updating to 0.7.0.dev0 (used 0.6.0 before) this below worked but i dont think it is correct behavior according to your documentation

Classification could be None for inference mode.

classifier = SDRClassifierFactory.create()

result = classifier.compute(
            recordNum=recordNum,
            patternNZ=patternNZ,
            classification={
                "bucketIdx": None,
                "actValue": None
            },
            learn=False,
            infer=True
)

@ywcui1990 Do you know the origin of this comment from the docs?
