我们从Python开源项目中，提取了以下14个代码示例，用于说明如何使用numpy.ma.make_mask_none()。
def test_hardmask(self): # Test hardmask base = self.base.copy() mbase = base.view(mrecarray) mbase.harden_mask() self.assertTrue(mbase._hardmask) mbase.mask = nomask assert_equal_records(mbase._mask, base._mask) mbase.soften_mask() self.assertTrue(not mbase._hardmask) mbase.mask = nomask # So, the mask of a field is no longer set to nomask... assert_equal_records(mbase._mask, ma.make_mask_none(base.shape, base.dtype)) self.assertTrue(ma.make_mask(mbase['b']._mask) is nomask) assert_equal(mbase['a']._mask, mbase['b']._mask)
def __array_finalize__(self, obj): # Make sure we have a _fieldmask by default _mask = getattr(obj, '_mask', None) if _mask is None: objmask = getattr(obj, '_mask', nomask) _dtype = ndarray.__getattribute__(self, 'dtype') if objmask is nomask: _mask = ma.make_mask_none(self.shape, dtype=_dtype) else: mdescr = ma.make_mask_descr(_dtype) _mask = narray([tuple([m] * len(mdescr)) for m in objmask], dtype=mdescr).view(recarray) # Update some of the attributes _dict = self.__dict__ _dict.update(_mask=_mask) self._update_from(obj) if _dict['_baseclass'] == ndarray: _dict['_baseclass'] = recarray return
