I wanted to re-offer for discussion a fix for a bug I reported a while
back. The code that breaks is this:
import numpy
cimport numpy
def testfunc():
a = numpy.arange(12).reshape([3,4])
cdef numpy.int_t[:,:] a_view = a
cdef numpy.int_t[:,:] b = a_view[:,:].T
One problem is that whe
s don't accept
arbitrary decorators, which is the typical way to use
kernprof/line_profiler. But I'm pretty happy to be able to use
kernprof/line_profiler on compiled pure-Python functions for now.
Thanks for your help!

Hi all,
I tried using line tracing in conjunction with line_profiler/kernprof to
attempt to see if line-based profiling works in Cython. I think it's
pretty close. But I think the problem is that line_profiler is getting
a different PyCodeObject when it wraps the function and when it actually
code.put_xdecref_memoryviewslice(
self.result(), have_gil=True)
+code.putln("%s.memview = NULL;" % self.result())
+code.putln("%s.data = NULL;" % self.result())
else:
ExprNode.generate_disposal_code(self, code)

Hi again,
I'm exploring the typed memoryview feature with numpy and encountered a
refcount error. It seems to happen when I create a slice of a
memoryview, and transpose it. If I don't do both, I don't get the
refcount error. It happens in the error cleanup code. I suspect that
any error
PyFFTW. It turns out
I will likely not be using it, but thought it was an interesting edge
case, and was what looked like valid Python, though it plays hard and
fast with Python's runtime binding...

Hi,
It seems that cython's static code analysis is failing on the following
code. It thinks that a particular variable (myobject2) must not be
NU
