Cannot install nupic on my virtualenv

Engineering NuPIC
1

I have created virtualenv for python 2 and install nupic.

It shown error "Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-zbwv_vt0/unittest2/".

Then I try to unintall nupic -y, I got “Skipping nupic as it is not installed.”

I do pip uninstall nupic.bindings. -y, I got the error as follows;

Invalid requirement: 'nupic.bindings.'

What should I do next? Thank you

Looks like the errors you’ve provided are not enough to debug your issue. Please provide information on how you have tried to install nupic. I would suggest post the steps from creating your virtualenv up to installing your nupic, until the point where you got the errors, please show the commands and the error log.

Hi Jose.

Did you find out what the problem was? Maybe you can share in case someone else has the same issue. :smiley:

Hi, I have also created a virtualenv for python 2.7 and cannot install nupic since I am getting a similar error to what you have previously experienced. How did you solve the problem?
Thanks!

These are the errors that I get:

Probably because NuPIC is still Python 2?

:see_no_evil: No idea why it’s still in Python 3, thank you for catching that!

CPython 2.7 won’t be supported much longer.

  You probably should try nupic.cpp. It runs on CPython 3.x.  But

check that the license is compatible with what you want to do.

Has anyone tried running Numenta’s version of nupic on Pypy - the
mostly-CPython-2.7-compatible one?
