Anacondas install messed with IPython pandas import?

I'm using IPython and pandas to do some number crunching, and recently installed Anaconda to try something out. I don't have virtualenv set up (I now learned my lesson as to why that is so valuable) and it must have tweaked something and now I'm getting an error importing pandas into my script. So far I've been able to find out that the pandas import is causing some trouble with an intel library libmkl_intel_lp64.dylib, but not much beyond that.

Sorry for the noobishness, can someone provide some insight on how to approach a solution? Thanks!

If you look at the traceback, you can see that it's loading things from Canopy, even though you are starting with Anaconda. This usually means you have PYTHONPATH set. You should unset it.

Check the environment variables PATH which should contain some path to the directory where Anaconda was installed, you will have to remove it in order to avoid calling the Anaconda's Python.

Then check PYTHONPATH, wich tells Python from where the modules should be imported, if there is any path to Anaconda's packages you can also remove it.

And finally, as you already realized... virtualenv is strongly recommended.
