This simple example causes a massive leak in v1.3.0 which didn't exist in v1.0.1. What am I doing wrong? If I replace arr = [Array((2,2)), Array((2,2))]
with arr = [numpy.ndarray((2,2,)), numpy.ndarray((2,2))] then I don't have the leak import numpy import gc class Array(numpy.ndarray): def __new__(subtype, shape, dtype=float, buffer=None, offset=0, strides=None, order=None, info=None): return numpy.ndarray.__new__(subtype, shape, dtype, buffer, offset, strides, order) def __array_finalize__(self, obj): print 'called array_finalize' if __name__=='__main__': arr = [Array((2,2)), Array((2,2))] nbytesAllocated = 0 for i in xrange(1000000000): a = numpy.array(arr) nbytesAllocated += a.nbytes if i%1000 == 0: print 'allocted %s'%nbytesAllocated gc.collect() -- --jlm -- --jlm -- --jlm
