How to find and uninstall the numpy duplicate versions

Question

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 ?

Answer 1

From the conda FAQ:

conda update numpy --no-pin

Answer 2

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.
