为pypy2.2.1安装numpy时出现错误

Question

I am trying to use pypy. My python scripts are using numpy. So when I used pypy 1.9.0 it showed me this:

"The 'numpy' module of PyPy is in-development and not complete. "
ImportError: The '`numpy' module` of PyPy is in-development and not complete. To try it out anyway, you can either import from 'numpypy', or just write 'import numpypy' first in your program and then import from 'numpy' as usual.

So I used import numpypy and then ran my script. I got this error:

File "customecode.py", line 97, in dist_new
    dlat = radians(p2[..., 0] - p1[..., 0])
TypeError: expected integer, got Ellipsis object

I couldn't find anything on this kind of error. Although script is running fine when I use python. So my guess is that may be pypy still don't support everything which is there on numpy.

I found this link on pypy-numpy update. So I install pypy 2.2.1 http://morepypy.blogspot.in/2013/11/numpy-status-update.html In this link following instructions are given for installing numpy for pypy:

git clone https://bitbucket.org/pypy/numpy.git
cd numpy
pypy setup.py install

after running pypy setup.py install I got this type error:

I want to use pypy 2.2.1 with whatever development of numpy provided there. Any help with the installation of numpy for pypy is appreciated.

Answer 1

In PyPy 2.2.1, the file lib-python/2.7/distutils/ccompiler.py does not contain any function called customize_compiler() and line 44 is not like that. My guess is that your version of PyPy's standard library has been tweaked by your Linux distribution in a way that makes it crash in your particular case.

I can only suggest that you try to get the "official" PyPy 2.2.1 and compare the results.
