Works fine in 2.0.10.

Hmmm, the plot thickens. It depends on which Ubuntu.

On Ubuntu 16.04, both 2.0.10 and 2.0.11 print the error above.

On Ubuntu 18.04, 2.0.10 is OK but 2.0.11 prints the error.

(I'm trying to import it in two otherwise identical virtual environments...)

I should rather say warning, as it proceeds to run afterwards anyway.

I can't replicate the issue on Ubuntu 18.04, python2 and 2.0.11 (virtualenv, tshikovski)

[gijzelaerr]

this is just not a KERN issue, closing this.

[o-smirnov]

@bennahugo, I first saw this here...

[gijzelaerr]

hm?

[o-smirnov]

Seeing the same error in a different context. Still haven't figured it out.

[gijzelaerr]

did you experiment with the numpy version? Some googlin hints that this might be a numpy 1.15 issue and running 1.16 solved it.
