Errors when Building the Cython modules and the gpu_nms, gpu_mask_voting modules

[ethanhe42]

I can't figure out what's wrong. Any idea?

Hi,

I cannot reproduce this error. It compiles well both on my TitanX (with numpy version 1.10.4, cython version 0.23.4) and K40 (with numpy version 1.11.0, cython version 0.23.5) machine, with Ubuntu 14.04 and cuda7.5.

Could you give me some detailed information about your system settings? (like numpy and cython version).

Hi @oh233 ,

yihuihe (master) lib $ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cython, numpy
>>> print cython.__version__, numpy.__version__
0.20.1post0 1.8.2

For GPU, I use Titan X

Hi,

Updating cython will solve this issue.

I tried with cython 0.20.1, the error occurs.

[ethanhe42]

Thanks. Problem solved!

[qinhaifangpku]

@yihui-he i happend to this error, what cython version does it need?
i am also output like this

print cython.version, numpy.version
0.20.1post0 1.8.2

[ethanhe42]

@qinhaifangpku cython version 0.23.4， cython version 0.23.5
