Help required regding Eigenvectors
by Sudheer Phani March 14, 2022

March 14, 2022

Hello All, I have been encountering some strange problems with the calculation of eigen vectors using python. The problem is with the sign of the eigen vectors calculated. On Very few occasions the eigen vectors calculated using python have an opposite sign than the actual eigenvectors, though the magnitude is correct. Can any one of you plz help me in this regard and suggest me some solution if you have encoutered similar problems . Any help in this regd is appreciated Thanks in Advace regds Sudheer

3D plotting
by Robert Cimrman Sept. 10, 2009

Sept. 10, 2009

Hi, I need to do some simple 3D plots, so I tried the two Cookbook recipes (xplt, mplot3d) and failed: * xplt: does not work when using a custom installation directory such as python setup.py install --root=/home/share/software apparently the gistdata directory path is wrong: gist.error: failed to create drawing -- Gist work.gs style sheet missing * mplot3d: does not work with my version of matplotlib (0.80). I have made the changes mentioned in the Cookbook to no avail. (Axes.__init__() args apparently changed, as well as some other matplotlib object attributes) Any ideas? mplot3d looks great, I would really like to use it! thanks, r.

problem with lsim

Jan. 9, 2007

I am having a problem with signal.lsim. Here is a script that recreates my problem: from scipy import * from pylab import plot t=arange(0,10,0.01) u=ones(shape(t)) sys=signal.lti([1.0],[1.0,1.0]) out=signal.lsim(sys,u,t) plot(out[0],out[1]) Here is the error message: I:\lsim_test.py 5 u=ones(shape(t)) 6 sys=signal.lti([1.0],[1.0,1.0]) ----> 7 out=signal.lsim(sys,u,t) 8 plot(out[0],out[1]) 9 c:\python24\lib\site-packages\scipy\signal\ltisys.py in lsim(system, U, T, X0, i nterp) 403 vt = transpose(v) 404 vti = linalg.inv(vt) --> 405 GT = dot(dot(vti,diag(numpy.exp(dt*lam))),vt).astype(xout.dtype.char ) 406 ATm1 = linalg.inv(AT) 407 ATm2 = dot(ATm1,ATm1) C:\Python24\Lib\site-packages\numpy\lib\twodim_base.py in diag(v, k) 66 i = arange(0,n+k) 67 fi = i+(i-k)*n ---> 68 res.flat[fi] = v 69 return res 70 elif len(s)==2: TypeError: can't convert complex to float; use abs(z) WARNING: Failure executing file: <lsim_test.py> My script is also attached if someone wants to run it.

General parallel processing question
by Anand Patil Dec. 4, 2006

Dec. 4, 2006

Hi again everyone, Say I have two objects A and B. A's member functions _occasionally_ want to call the member functions of B, and vice versa. Both A and B have to do a lot of work between calls to each other's member functions. I'd like to push B off to a new process, but be able to program as if it were still in the same process as A. That is, I'd like to be able to call B's member functions from A without having to teach A how to do interprocess communication. The solution I've been thinking of is to write 'avatar' objects that represent objects living in different processes and know how to pass member function calls along to their 'true selves' (probably using mpi4py and/or IPython1, but I haven't worked out the details yet). If A lives in process 0 and B gets pushed to process 1, I would create an avatar of B in process 0 and one of A in process 1. That scheme would get kind of klunky, though. Has anyone thought about/ dealt with this situation before? Thanks, Anand

umfpack and building scipy from source
by Ryan Krauss Dec. 1, 2006

Dec. 1, 2006

I am trying to build scipy/numpy from source on Windows XP. I do not have umfpack installed. When I build scipy I get this warning: C:\Python24\lib\site-packages\numpy\distutils\system_info.py:401: UserWarning: UMFPACK sparse solver (http://www.cise.ufl.edu/research/sparse/umfpack/) not found. Directories to search for the libraries can be specified in the numpy/distutils/site.cfg file (section [umfpack]) or by setting the UMFPACK environment variable. warnings.warn(self.notfounderror.__doc__) numpy.test() runs without problems. The output of scipy.test() is slightly scary: scipy.test() RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 Found 397 tests for scipy.ndimage RuntimeError: module compiled against version 1000002 of C-API but this version of numpy is 1000009 Warning: FAILURE importing tests for <module 'scipy.sparse.sparse' from '...ckages\\scipy\\sparse\\sparse.pyc'> C:\Python24\Lib\site-packages\scipy\linsolve\_superlu.py:2: ImportError: numpy.core.multiarray failed to import (in ?)

I had some trouble getting numpy's setup.py to find the atlas, lapack, blas libs until I set an ATLAS environment variable. Oh, and the example site.cfg mentions libamd.a as well as umfpack. Do I need the amd lib? I am running an amd processor under windows (Athlon X2). Thanks, Ryan

nan?
by Joshua Petterson Nov. 30, 2006

Nov. 30, 2006

hello, my question is maybe trivial, but what is the utility of numpy.NAN? In [60]: nan==nan Out[60]: False In [61]: a=ma.masked_object((1,2,nan),nan) In [62]: a Out[62]: array([ 1. 2. nan]) In [63]: b=array([(1,2,3),(4,5,nan)]) In [64]: b.max() Out[64]: 5.0 In [65]: b.mean() Out[65]: nan thanks

how to copy several rows/columns to a sparse matrix?
by Zhang Sam Nov. 30, 2006

Nov. 30, 2006

Hi, there I want to use sparse matrix with scipy. But I can't copy several rows/columns to a coo_matrix at the same time. The codes is as follows: ------------------------------------------------------------------------------------------------------------------------------------------ >>> from numpy import * >>> from scipy import * >>> a=sparse.coo_matrix((array([1,2,3]),[[0,1,2],[0,1,2]]), (3,3)) >>> a <3x3 sparse matrix of type '<type 'float64scalar'>' with 3 stored elements in COOrdinate format> >>> print a (0, 0) 1.0 (1, 1) 2.0 (2, 2) 3.0 >>> b = array([[1,2,3],[4,5,6]]) >>> b array([[1, 2, 3], [4, 5, 6]]) >>> a[[0,1],:] = b Traceback (most recent call last): File "<interactive input>", line 1, in ? File "D:\Python24\lib\site-packages\scipy\sparse\sparse.py", line 237, in __getattr__ raise AttributeError, attr + " not found" AttributeError: __setitem__ not found ----------------------------------------------------------------------------------------------------------------------------------------------- Maybe it is not very clear. I also show a same type operation however with numpy arrays. --------------------------------------------------------------------------------------------- >>> a = arange(8) >>> a.shape = 2,4 >>> a array([[0, 1, 2, 3], [4, 5, 6, 7]]) >>> b = array([4,4,4,4]) >>> b.shape=2,2 >>> b array([[4, 4], [4, 4]]) >>> a[:,[1,2]]=b >>> a array([[0, 4, 4, 3], [4, 4, 4, 7]]) --------------------------------------------------------------------------------------------- Why this happens? Does sparse matrix defined in scipy need different operation? Thanks in advance.

I dug this out of the archives from January '06; I'm still getting the same behaviour with python 2.4.3, compiled to Mac OS 10.4.5 with gcc 4.0.1 using scipy 0.5.2.dev2095. I came at it a different way and first discovered that erf(48.0083465504) gives nan. I'm going to tackle David Cooke's suggestion above and was wondering which file the "#define erf cephes_erf" header ought to go in? Also, if anyone knows the current status of this issue, I'd appreciate hearing about that, too. -J

What about 'None'? Comment about nan...
by Martin Kuemmel Nov. 30, 2006

Nov. 30, 2006

Hi, this question may (as well) be trivial for some of us, but bothers me for some time. It is: >>> gaga = numpy.array([1.0,2.0,None]) >>> gaga array([1.0, 2.0, None], dtype=object) The type of the array is 'object'. Is there a way to have 'None' in a numerical array type? Any trick, idea or recipe? About nan: It is great that 'numpy.NAN' exists, but the handbook says nothing about it. Are there more glorious, but hidden constants or functions or methods?
