I am newbie, help me run code


#21

Try the --user flag, which tells python to install in non-system locations:

pip install nupic --user

This advice is also in the README.


#22

yes. i run your command. but how can i run

your code, and i dont understand

From the root of the repo:

py.test tests/unit

can you help me?


#23

Do you have any experience programming in Python?


#24

no. i dont have any experence in python. i am newbie. i often use matlab. i just want to run it. but in python too hard to open one project. it is not similar to matlab.


#25

can you tell me how can i run your code. i really want to see the results.


#26

You do need to have some programming experience to run NuPIC. To test to see if you have NuPIC installed, you can run this sample code, which feeds scalar timestamped data into NuPIC:

python examples/opf/clients/hotgym/simple/hotgym.py

You should get output that looks like this (except the MAPE will be a bit different):

INFO:__main__:After 100 records, 1-step altMAPE=24.259312
INFO:__main__:After 200 records, 1-step altMAPE=17.637056

INFO:__main__:After 800 records, 1-step altMAPE=15.303115
INFO:__main__:After 900 records, 1-step altMAPE=15.445490

I must state, however, that this is forum is not the place to get general programming help or python help. We do expect users to have some basic familiarity with programming in general and Python.


#27

thank you. i run your code. this is result

is that fine?
sorry, i am just student, so i dont have expirence on python and HTM.
thank your help


#28

Looks like it is working, but like @Jonathan_Mackenzie said earlier, HTM doesn’t do well on image recognition. NuPIC’s current implementation of HTM is focused only on sequence memory (temporal sequences). Spatial recognition is not its strong point.


#29

oh. because my project is using HTM to recognize digits handwritten. so it means my project willnot have good result. isnot it?


#30

ohh. you are Matt Taylor. i am watching your lessons on youtube. sorry, i dont recognize you. thank for your lessons.


#31

That’s correct. HTM cannot beat other methods of learning handwriting. You are welcome for the videos :slight_smile:
