weave failures on OSX
by Christopher Fonnesbeck 30 Jun '03

30 Jun '03

I have some inline statements that work wonderfully under Linux, but on OSX (python2.3 using recent CVS weave), they die the death. Note that weave.test() on my machine runs cleanly. Any clues would be most appreciated. Here is the code and the resultant errors: code = ''' #line 610 "ReinforcementLearning.py" PyObject *key, *qval, *traceval = NULL; Py::List keys = qfunction.keys(); for (int i=0; i<keys.length(); i++) { key = PyList_GET_ITEM(keys.ptr(),i); /* Grab and convert current Q-value */ qval = PyDict_GetItem(qfunction.ptr(),key); double qval_raw = py_to_float(qval,"qval_raw"); /* Grab and convert current elegibility value */ traceval = PyDict_GetItem(etrace.ptr(),key); double traceval_raw = py_to_float(traceval,"traceval_raw"); /* Calculate new Q-value */ qval_raw += alpha * delta * traceval_raw; /* Return new Q-value to Q-function */ PyObject* qval_new = PyFloat_FromDouble(qval_raw); PyDict_SetItem( qfunction.ptr(), key, qval_new ); /* Cleanup */ Py_DECREF(qval_new); /* Only update nonzero e-trace values */ if (traceval_raw>0.0) { /* Only interested in sizeable values */ if (traceval_raw>=tolerance) { /* Calculate new elegibility value */ traceval_raw = gamma * lamda * traceval_raw; /* Return new elegibility value to trace */ PyObject* traceval_new = PyFloat_FromDouble(traceval_raw); PyDict_SetItem( etrace.ptr(), key, traceval_new ); /* Cleanup */ Py_DECREF(traceval_new); } /* Set very small values to zero */ else PyDict_SetItem( etrace.ptr(), key, PyFloat_FromDouble(0.0) ); } } ''' 'Call to weave' weave.inline(code, ['qfunction', 'alpha','delta','etrace', 'gamma','lamda','tolerance']) This results in: ReinforcementLearning.py: In function `PyObject* compiled_func(PyObject*, PyObject*)': ReinforcementLearning.py:612: `Py' undeclared (first use this function) ReinforcementLearning.py:612: (Each undeclared identifier is reported only once for each function it appears in.)

Hey folks, I've been postponing this announcement because the registration page isn't active yet. It's getting late though, and I thought I'd at least let you know SciPy '03 is happening. I'll repost when registration is open. Thanks, Eric ------------------------------------------------------- SciPy '03 The 2nd Annual Python for Scientific Computing Workshop ------------------------------------------------------- CalTech, Pasadena, CA September 11-12, 2003 http://www.scipy.org/site_content/scipy03 This workshop provides a unique opportunity to learn and affect what is happening in the realm of scientific computing with Python. Attendees will have the opportunity to review the available tools and how they apply to specific problems. By providing a forum for developers to share their Python expertise with the wider industrial, academic, and research communities, this workshop will foster collaboration and facilitate the sharing of software components, techniques and a vision for high level language use in scientific computing. The cost of the workshop is $100.00 and includes 2 breakfasts and 2 lunches on Sept. 11th and 12th, one dinner on Sept. 11th, and snacks during breaks. Online registration is not available yet, but will be soon. We would like to have a wide variety of presenters this year.

scipy_distutils: fortran without f2py
by David Grote 26 Jun '03

26 Jun '03

I need help with scipy_distutils. I can't figure out how to get it to do what I need. I am trying to find a nice package which will help build python extensions, some of which is written in fortran, and scipy_distutils looks good. For various reasons, I create my own wrappers and so I don't need the wrapper to be generated by f2py. However, with everything I have tried with scipy_distutils, it either insists on using f2py, or does nothing. Does anyone have an example setup.py that I could see which would help, something that doesn't use f2py? F2py is a great piece of software but there are some things I need that it doesn't do (like wrap fortran derived types). Any help would be much appreciated! Thanks! Dave Grote

How to use CVS etc.
by Cliff Martin 24 Jun '03

24 Jun '03

In posts around June 4 I saw that the io.read_array that didn't read negative numbers was fixed and 'in CVS'. I'm currently using SciPy .2 under Windows 2000. Is there some directions of how to get the fix into my setup. Sorry for being so stupid about this. If I was in Linux I'd just download the new source and recompile etc. but I'm not sure what steps I've got to take in Windows. Cliff Martin

sparse function
by Nils Wagner 17 Jun '03

Hi all, Is there a function in scipy which converts a full matrix to sparse form by squeezing out any zero elements ? How do I use it ? Nils
