示例1: test_stdev
# 需要导入模块: from thunder.rdds.fileio.imagesloader import ImagesLoader [as 别名]
# 或者: from thunder.rdds.fileio.imagesloader.ImagesLoader import stdev [as 别名]
def test_stdev(self):
from test_utils import elementwiseStdev
arys, shape, size = _generateTestArrays(2, 'uint8')
imageData = ImagesLoader(self.sc).fromArrays(arys)
stdval = imageData.stdev()
expected = elementwiseStdev([ary.astype('float16') for ary in arys])
assert_true(allclose(expected, stdval))
assert_equals('float64', str(stdval.dtype))示例2: test_stdev
# 需要导入模块: from thunder.rdds.fileio.imagesloader import ImagesLoader [as 别名]
# 或者: from thunder.rdds.fileio.imagesloader.ImagesLoader import stdev [as 别名]
def test_stdev(self):
from test_utils import elementwise_stdev
arys, shape, size = _generate_test_arrays(2, 'uint8')
imagedata = ImagesLoader(self.sc).fromArrays(arys)
stdval = imagedata.stdev()
expected = elementwise_stdev([ary.astype('float16') for ary in arys])
assert_true(allclose(expected, stdval))
#assert_equals('float16', str(stdval.dtype))
# it isn't clear to me why this comes out as float32 and not float16, especially
# given that var returns float16, as expected. But I'm not too concerned about it.
# Consider this documentation of current behavior rather than a description of
# desired behavior.
assert_equals('float32', str(stdval.dtype))
