ImportError: numpy.core.multiarray failed to import

Code:

Seems like maybe I need to install an updated version of something in workspaces?

I'm getting the same error, but if I download the workspace and run on my local environment (Python 3.5.1 |Anaconda 2.4.1 (x86_64)) everything works as expected.

I tried running "pip install -U numpy " in workspaces to see if this would fix the problem, but the installer would freeze and not finish the installation...

Updating numpy in Workspaces worked for me, it just took a while (~10 minutes).

pip install --upgrade numpy

Output:

    100% |████████████████████████████████| 4.7MB 66kB/s

You are using pip version 7.1.2, however version 8.1.2 is available.                             
You should consider upgrading via the 'pip install --upgrade pip' command.                       
pyenv: cannot rehash: /usr/local/pyenv/shims isn't writable

Code successfully ran after this. I'm just hoping the install persists after I close Workspaces :X

I am having a similar issue, and am frustrated by the lack of support by the Treehouse community on this issue. It means all the lessons (certainly bar charts, tables, or anything else related to numpy) hereafter are not going to work. Workspaces is one of the things that sets treehouse apart (I can study on my chromebook on the go!) so I will move on to use an alternative resources if no solutions are found to this issue!
