I am trying to install the library GPy. Although the installation is successful, I have a question on my numpy version.

GPy library can be found here https://github.com/SheffieldML/GPy

The current version of my numpy is 1.9.3

>>> import numpy
>>> numpy.version.version
'1.9.3'

But when I perform python setup.py install for GPy, it refers to numpy 1.10.0. I checked in python 2.7/site-packages there only one version of numpy exist that too 1.9.3 

Using /home/vinod/anaconda/lib/python2.7/site-packages
Searching for scipy==0.16.0
Best match: scipy 0.16.0
Adding scipy 0.16.0 to easy-install.pth file

Using /home/vinod/anaconda/lib/python2.7/site-packages
Searching for numpy==1.10.0
Best match: numpy 1.10.0
Adding numpy 1.10.0 to easy-install.pth file

Using /home/vinod/anaconda/lib/python2.7/site-packages
Finished processing dependencies for GPy==0.8.8
vinod@vinod-Lenovo-G580:~/GPy$

Since it's referring to another version am getting error like 

File"__init__.pxd", line 155, in init GPy.util.linalg_cython (GPy/util/linalg_cython.c:4238)
ValueError: numpy.dtype has the wrong size, try recompiling

Could anyone tell me how to find and remove the numpy 1.10.0 ?

  • I'm getting this same issue when trying to install pandas via pip. I have numpy 1.9.2 installed, but pandas reports that it's trying to use numpy 1.10.0. – Jeff Klukas Oct 07 '15 at 18:42
  • Are you using anaconda, if not please try it, it includes almost all necessary libraries including pandas. – Vinod Prime Oct 08 '15 at 07:42

From the conda FAQ:

conda update numpy --no-pin

  • vinod@vinod-Lenovo-G580:~$ conda update numpy --no-pin Fetching package metadata: .... # All requested packages already installed. # packages in environment at /home/vinod/anaconda: # numpy 1.9.3 py27_p0 [mkl] But still am getting the same error. – Vinod Prime Oct 07 '15 at 16:36
  • What about `conda remove numpy` followed by `conda install numpy`? – Zac Crites Oct 07 '15 at 17:00

I tried the following steps and it works but still I don't know how.

  1. I opened the setup.py and changed the numpy condition from numpy >= 1.7 to numpy <=1.9.3
  2. Then I performed the python setup.py install
  3. Then I uninstalled GPy using pip uninstall GPy
  4. Again I installed GPy but using pip install GPy. Note: in previous steps I used git and installed separately.
  5. This time it upgraded my numpy to 1.10.0 during installation and got installed successfully
  6. Finally now it works well.
