[Numpy-discussion] Two bugs in numerictypes.py

[Edward C. J. <edc...@er...>]

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.

[Numpy-discussion] Have a problem: what is attribute 'compress'

[Sebastian H. <ha...@ms...>]

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.

Todd

Re: [Numpy-discussion] Have a problem: what is attribute 'compress'

[Sebastian H. <ha...@ms...>]

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)
Traceback (most recent call last):
  File "<input>", line 1, in ?
  File "C:\Python22\Lib\site-packages\numarray\numarray.py", line 581, in

  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'

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

Thanks,
Sebastian

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? ...
