Thanks for the report, I'll look into it. I know it's broken with crystax, but I thought it was working for the normal NDKs.

[bobatsar]

I have the same issue here. Is there any workaround to get it working again?

[maho]

the same here

[GeorgeKesaev]

Same here on 3 different pcs
Edit:
I really need numpy for my project, do you have any ideas on where to look, I could try to fix it myself.
Thank you.

[omarsgalal]

same problem here

[hutauf]

same here. is there any kind of workaround?

[hutauf]

your fix works for me, thanks @mahomahomaho

[art049]

I still have the same problem even with @mahomahomaho fix. Which version of numpy is working for you ?
Edit: I got it working, I think the problem was that I didn't have libatlas

[AndreMiras]

numpy + python2 is working as demonstrated in continuous integration #1304
Feel free to reopen if you have an updated broken case.
