nupic.bindings install problem: IOError: [Errno 2] No such file or directory: '/tmp/VERSION'

[matousc89]

When I call: sudo -H pip install nupic.bindings, I get the following error:

I don't recommend you install with sudo. What happens when you run pip install nupic --user?

[matousc89]

It throws the same error. Another idea?

[rhyolight]

Do you have write access to /tmp?

[matousc89]

Yes. I double checked it. I have regular access settings for /tmp - so I can write there.

[rhyolight]

Can you try to uninstall nupic completely before running pip install nupic --user again? @scottpurdy during the installation of nupic.bindings, what writes to /tmp?

[scottpurdy]

@scottpurdy during the installation of nupic.bindings, what writes to /tmp?

I believe pip uses /tmp as the default for its cache (downloads, etc). You can change it by setting the TMPDIR env dir while running the pip command.

I uninstall the nupic completely. Now I get:

This looks like a python 2 vs 3 error. Things like this usually happen when there are conflicting versions of python and / or pip installed on a system.

Try pip uninstall unittest2, then install again.

[matousc89]

Done with no success. Any other hint?

[rhyolight]

The error you are getting implies that you are running python 3, and NuPIC is only compatible with python 2. I'm not sure how to help you figure out why pip is running python 3, but you should check to see what version of python is in your path and what versions are installed on your system. You should also investigate what versions of pip you have installed.

Just to be sure I ran pip2 install nupic --user and I am back to previous error:

If I try to run pip2 install nupic.bindings, I get the previous error with /tmp

What operating system? 32b or 64b?

[matousc89]

Ubuntu, 32b at home, 64b at work. The same error on both machines.

[rhyolight]

The problem is that we do not support 32b systems. :(
