Hi all, In the numpy.sctypes dictionary, there are two entries for uint32:
In [2]: N.sctypes['uint'] Out[2]: [<type 'numpy.uint8'>, <type 'numpy.uint16'>, <type 'numpy.uint32'>, <type 'numpy.uint32'>, <type 'numpy.uint64'>] Comparing the dtypes of the two types gives the correct answer: In [3]: sc = N.sctypes['uint'] In [4]: N.dtype(sc[2]) == N.dtype(sc[3]) Out[4]: True But the hash values for the dtypes (and the types) differ: In [42]: for T in N.sctypes['uint']: dt = N.dtype(T) print T, dt print '=>', hash(T), hash(dt) <type 'numpy.uint8'> uint8 => -1217082432 -1217078592 <type 'numpy.uint16'> uint16 => -1217082240 -1217078464 <type 'numpy.uint32'> uint32 => -1217081856 -1217078336 <type 'numpy.uint32'> uint32 => -1217082048 -1217078400 <type 'numpy.uint64'> uint64 => -1217081664 -1217078208 Is this expected/correct behaviour?
