about using python class in weave
by Yijue Hou Oct. 1, 2002

Oct. 1, 2002

weave.inline call use python integers directly, but while I tried to use python classes, it doesn't work. suppose s is a python class, my code: weave.inline("s.blah();",['s']) it said it unable to convert to c++ types, so how to call python classes in c function using weave? Thanks

atlas/clapack/etc problems.
by Louis Cordier Oct. 1, 2002

Oct. 1, 2002

Hi, I need lots of help, pleeeeeeeease (; My goal is to run Python2.2 on a 60 Workstation Cluster (Debian3.0), using scipy.cow. However I cant even get scipy to work. I tried to build scipy on a Red Hat 7.3 box, and after the clapack/cblas module import errors, I gave up and moved on to Debian 3.0 (woody). Especially after I read about Automatic ATLAS support under Debian GNU/Linux http://lists.debian.org/debian-devel/2001/debian-devel-200111/msg00823.html Don't get your hopes up thou. I tried just about everything, using only BLAS/LAPACK, building ATLAS from source (many many times), this makes .so's. Then making the symlinks from the *.so.2 -> *.so so that scipy_distutils/system_info.py can detect them. With the right values for {$ATLAS,$BLAS,$LAPACK}, else it has difficulty finding them even with site.cfg setup right. I even tried the binary prebuild scipy. I tried both these methods: http://www.scipy.org/site_content/tutorials/install_binaries http://www.scipy.org/site_content/tutorials/build_instructions Nothing works, the binary install needs access to the header files and after a copied it from the source and ran the {setup_scipy.py,setup_scipy_base.py,setup_scipy_distutils.py} scripts, this is as far as I get.

Hi all, I've installed the latest SciPy*.exe on Windows2000.

Problem installing binaries/source on Debian
by José Luis Gómez Dans Sept. 24, 2002

Sept. 24, 2002

Hi, I had been using the debian packages of scipy 0.1, but since I did a couple of upgrades in the system, these disappeared from sight (sigh!). So I set out to install from source, and wasn't able to do it (there was a missing module; unfortunately, I do not have a log of that, and hard disk space is tight at the moment to submit a proper report). I got hold of the binary packages, and tar -zxvf'd the download file for Python2.1 on /usr/lib/python2.1/site-packages/. Trying my scripts results in: Traceback (most recent call last): File "./extract_data.py", line 5, in ? from scipy import * ImportError: No module named scipy I then changed some of the permissions of the downloaded files (they had numeric UID and so on), but still get the same result. So I installed python2.2, and gave it a try. this time, the package is found (I did install in /usr/local/lib/python2.2/site-packages/, realising that it was a far more logical place for it to be). This is a traceback: Python 2.2.1 (#2, Sep 13 2002, 23:25:07) [GCC 2.95.4 20011002 (Debian prerelease)] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from scipy import * Traceback (most recent call last): File "<stdin>", line 1, in ? File "/tmp/SciPyTest/linux2/lib/python2.2/site-packages/scipy/__init__.py", line 62, in ? File "/tmp/SciPyTest/linux2/lib/python2.2/site-packages/scipy/weave/__init__.py", line 14, in ? ImportError: cannot import name inline So, no scipy module available... Having said that, I have just tried to import the io module and have succeeded by doing this: from scipy_base import * from scipy import * Traceback (most recent call last): File "./extract_data.py", line 6, in ? from scipy import * File "/tmp/SciPyTest/linux2/lib/python2.2/site-packages/scipy/__init__.py", line 62, in ? File "/tmp/SciPyTest/linux2/lib/python2.2/site-packages/scipy/weave/__init__.py", line 14, in ? ImportError: cannot import name inline from scipy import * from scipy.io import * (Note that I had to import scipy twice). So I import scipy, I get an error on the weave/inline_tools import, saying that it cannot import inline. However, if I retry this same statement, it can the import inline namespace thing. If you need any more info, please let me know. Any hints on what's going on much appreciated!!!!

Chaco discussion on scipy-chaco mailing list
by David C. Morrill Sept. 23, 2002

Sept. 23, 2002

Just wanted to mention that Chaco has its own mailing list on scipy-chaco(a)scipy.org. To avoid unnecessary cross-posting on the other SciPy lists, hopefully future Chaco discussion will occur there. In particular, I just posted a note there on the progress I've made in fixing the Chaco Linux problem that has been reported by several people. See ya there... Dave Morrill
