In "numerictypes.py' it says "This module is designed so 'from numerictypes import *' is safe." When I "import numerictypes", and run dir(), I get:
['Any', 'AnyType', 'Bool', 'BooleanType', 'Byte', 'Complex', 'Complex32', 'Complex64', 'ComplexType', 'Double', 'Float', 'Float32', 'Float64', 'FloatingType', 'Int', 'Int16', 'Int32', 'Int64', 'Int8', 'IntegralType', 'Long', 'MAX_ALIGN', 'NumericType', 'Short', 'SignedIntegralType', 'SignedType', 'UInt16', 'UInt32', 'UInt64', 'UInt8', 'UnsignedIntegralType', 'UnsignedType', '__builtins__', '__doc__', '__name__', 'genericCoercions', 'genericPromotionExclusions', 'genericTypeRank', 'inttype1', 'inttype2', 'kind', 'mapto', 'maptype1', 'maptype2', 'nt1', 'nt2', 'ntypesize1', 'ntypesize2', 'numinclude', 'outtype', 'pythonTypeMap', 'pythonTypeRank', 'rank1', 'rank2', 'scalarTypeMap', 'signedtype1', 'signedtype2', 'typeDict', 'typecode', 'typecodes']
A bunch of leading "_" are needed.
----------------
My code is:
#! /usr/bin/env python from numerictypes import UInt8 print UInt8 == "ABC"
The message is:
Traceback (most recent call last): File "./silly02.py", line 5, in ? print UInt8 == "ABC" File "/usr/lib/python2.2/site-packages/numarray/numerictypes.py", line 101, in __cmp__ other = typeDict[other] KeyError: ABC
I would expect that the only object == to UInt8 be itself. Maybe add a function comparetypecodes(x, y) which returns True iff x and y are either NumericType's or strings which represent the same type.
Hi! Somehow I have a problem with numarray. Please take a look at this:
import numarray as na na.array([0, 0])
array([0, 0])
na.array([0.0, 0.0])
Traceback (most recent call last): File "<input>", line 1, in ? File "C:\Python22\Lib\site-packages\numarray\numarray.py", line 581, in __repr__ MAX_LINE_WIDTH, PRECISION, SUPPRESS_SMALL, ', ', 1) File "C:\Python22\Lib\site-packages\numarray\arrayprint.py", line 163, in array2string separator, array_output) File "C:\Python22\Lib\site-packages\numarray\arrayprint.py", line 125, in _array2string format, item_length = _floatFormat(data, precision, suppress_small) File "C:\Python22\Lib\site-packages\numarray\arrayprint.py", line 246, in _floatFormat non_zero = numarray.abs(numarray.compress(numarray.not_equal(data, 0), data)) AttributeError: 'module' object has no attribute 'compress'
The same workes fine with Numeric. But I would prefer numarray because I'm writing C++-extensions and I need "unsigned shorts".
What is this error about?
Thanks, Sebastian

Hi Sebastian,
I've don't recall seeing anything like this, nor can I reproduce it now. If you've been following numarray for a while now, I can say that it is important to remove the old version of numarray before installing the new version. I recommend deleting your current installation and reinstalling numarray.
compress() is a ufunc, much like add() or put(). It is defined in ndarray.py, right after the import of the modules ufunc and _ufunc. _ufunc in particular is a problematic module, because it has followed the atypical development path of moving from C-code to Python code. Because of this, and the fact that a .so or .dll overrides a .py, older installations interfere with newer ones. The atypical path was required because the original _ufuncmodule.c was so large that it could not be compiled on some systems; as a result, I split _ufuncmodule.c into pieces by data type and now use _ufunc.py to glue the pieces together.
Good luck! Please let me know if reinstalling doesn't clear up the problem.

Hi, I can print numarray of any int time just fine, but I still get the compress error message with Float (or complex) data:
c array([[0, 0, 0, ..., 0, 0, 0],
[0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0], ..., [0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0], [0, 0, 0, ..., 0, 0, 0]], type=UInt16)
c.astype(na.Float)

I get this on Windows (2000) and on Linux. Both numarray 0.4

OK. I am assuming you deleted all of your old numarray installations as I recommended and reinstalled numarray-0.4.
What is your PYTHONPATH?

I'm not sure what's going on here, but I develop on both platforms, and Linux constantly. The self tests definitely pass in Linux. It must be some kind of environment issue or runtime issue. What happens when you type:
import numtestall numtestall.test()
... what gets printed here? ...
