We tested with python 2.7 and we are getting the exact same issue.

I had this issue with both bcolz and bottleneck importing from numpy. I believe for me it was an issue with both packages being installed with an incorrect version of numpy I had cached on my machine. I was able to resolve both by uninstalling them and running pip install with the --no-cache-dir option.

These are the commands I ran:

pip uninstall bcolz
pip install bcolz --no-cache-dir
pip uninstall bottleneck
pip install bottleneck --no-cache-dir

I'm having a similar issue although not exactly the same, figured I'd post it here:

Thanks for the quick response, but no change. I tried that earlier when I initially encountered the error. I'll keep playing with it to see if I can find a fix, but may just give up and set it up on Ubuntu.

Try sending me the output of this command if you can:

pip freeze --local

I'll diff it with mine. Which OS are you using now?

@itsjaked as I referenced in my previous post with other packages, if you run pip uninstall catalyst and then pip install catalyst --no-cache-dir, I believe your error will be resolved

@brandonclosson Awesome, thanks, issue has been resolved. I did try that previously, but most likely had another dependency issue at that time.

@fredfortier @brandonclosson I've tried --no-cache-dir and various package version on several packages (bcolz, bottleneck, numpy, catalyst) through python2/3 without any success. However running pip install enigma-catalyst matplotlib --no-cache-dir in the first place, fixed this. Thanks!
