I have carefully follow the suggested post below.

[https://discourse.numenta.org/t/running-nupic-on-raspberry-pi-having-problems/1667](https://discourse.numenta.org/t/running-nupic-on-raspberry-pi-having-problems/1667)

By using pyenv, Nupic core build is failed. Without using pyenv, I could build nupic core on a Raspbery Pi. I can import nupic.bindings in Python.

But, in the last step, when I try to install Nupic from source, I had a following error message.

* * *

pi@raspberrypi:~/nupic $ python [setup.py](http://setup.py) develop --user  
Traceback (most recent call last):  
File “[setup.py](http://setup.py)”, line 134, in   
requirements = findRequirements()  
File “[setup.py](http://setup.py)”, line 121, in findRequirements  
if nupicBindingsPrereleaseInstalled():  
File “[setup.py](http://setup.py)”, line 55, in nupicBindingsPrereleaseInstalled  
if pkg\_resources.parse\_version(nupicDistribution.version).is\_prerelease:  
AttributeError: ‘tuple’ object has no attribute ‘is\_prerelease’

I think this error would not be related to Raspbery Pi.

I’ m really wanted to run Nupic on a Rasberry Pi.  
Any idea about this error?
