MemoryError in Haralick feature #69

Closed hackermd closed 8 years ago

hackermd commented 8 years ago

Working with a uint16 image, I got the following error in mahotas.features.texture line 112:

---------------------------------------------------------------------------
MemoryError                               Traceback (most recent call last)
<ipython-input-6-efdb5c1eef9d> in <module>()
----> 1 np.empty((fm1, fm1), np.int32)

MemoryError:

In this case the value of fm1 was 37531.

Sorry, it seems this is not related to your code. I can not reproduce this problem on another machine..

This is actually an FAQ:

http://mahotas.readthedocs.org/en/latest/faq.html#i-ran-out-of-memory-computing-haralick-features-on-16-bit-images-is-it-not-supported

I suppose we could do a little better in the error message department, but mahotas is trying to do what it's asked of it, but it doesn't have enough memory to do so.

Thanks for your feedback! I think this issue is already sufficiently addressed in the FAQs, I should have simply read them before creating this issue.
