Hello,
I need to pickle the type numpy.float32 but encounter an error when I
try to do so. I am able to pickle the array itself, it is specifically
the type that I cannot pickle.
I am using:
Numpy version: 0.9.4
Python version: 2.4.3
Windows XP
Here is the code that reproduces the error:
_______________ _______________ ________
import numpy
import pickle
pickle.dumps(nu mpy.float32)
Output:
PicklingError: Can't pickle <type 'float32_arrtyp e'>: it's not found as
__builtin__.flo at32_arrtype
_______________ _______________ ________
Any suggestions would be much appreciated.
Thanks,
Iljya Kalai 3 3601
I have reproduced the error with Numpy 1.0b1
The output with v.1.0b1 reads:
PicklingError: Can't pickle <type 'float32scalar' >: it's not found as
__builtin__.flo at32scalar
Has anyone else encountered this?
Thanks,
Iljya

This looks like a numpy bug. It seems that float32_arrtype 's name is
incomplete. Its tp_name field should start with a module name, but
since it doesn't, Python assumes that it is a builtin type:
>>import numpy numpy.float32 .__module__
'__builtin__'
You should report this bug either to the numpy list: https://lists.sourceforge.net/lists/...mpy-discussion
or to their bug tracker: http://projects.scipy.org/scipy/numpy

Thanks, Ziga
I have submitted the bug to http://projects.scipy.org/scipy/numpy
I am using the following workaround for now:
>>import numpy import pickle import __builtin__ __builtin__.f loat32_arrtype = numpy.float32 pickle.dumps( numpy.float32)
'c__builtin__\n float32_arrtype \np0\n.'
The name binding must also be present when unpickling.

Has anyone recompiled the Scientific Computing package using NumPy instead
of Numeric?
I need a least squares algorithm and a Newton Rhaphson algorithm which is
contained in Numeric but all the documentation out there says that Numeric
is crap and all code should be using NumPy.

Hello,
I use the Python Numeric package extensively, and had been an
avid user of the "old" scipy. In my view, both pieces of software
are truly first rate, and have greatly improved my productivity in
the area of scientific analysis. Thus, I was excited to make the
transition to the new scipy core (numpy).
Unfortunately, I am experiencing a problem that I cannot sort
out. I am running Python 2.4.2 on a Debian box (V3.1), using

Hello all,
I'm pretty new to Python, but use it a lot lately. I'm getting a crazy
error trying to do operations on a string list after importing numpy.
Minimal example:
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) on win32
Type "help", "copyright", "credits" or "license" for more information.

Hey All,
I am working with numpy
I have a data set with a lot of nan values, and i want to calculate standard
deviation
is there a direct function to do it for example nansum(or something like
this),
to calculate standard deviation ignoring nan values??
Thanks

scipy.stats.nanstd() implements this. Additionally, data.std()
works unless if you need to apply the std() along just one axis.
