示例1: test_minhash_abund_merge_flat
# 需要导入模块: from sourmash._minhash import MinHash [as 别名]
# 或者: from sourmash._minhash.MinHash import similarity [as 别名]
def test_minhash_abund_merge_flat():
# this targets a segfault caused by trying to compute similarity
# of a signature with abundance and a signature without abundance.
# the correct behavior for now is to calculate simple Jaccard,
# i.e. 'flatten' both of them.
a = MinHash(0, 10, track_abundance=True, max_hash=5000)
b = MinHash(0, 10, max_hash=5000)
for i in range(0, 10, 2):
a.add_hash(i)
for j in range(0, 10, 3):
b.add_hash(i)
# these crashed, previously.
assert a.similarity(b) == 0.2
assert b.similarity(a) == 0.2示例2: test_div_zero
# 需要导入模块: from sourmash._minhash import MinHash [as 别名]
# 或者: from sourmash._minhash.MinHash import similarity [as 别名]
def test_div_zero(track_abundance):
# verify that empty MHs do not yield divide by zero errors for similarity
mh = MinHash(1, 4, track_abundance=track_abundance)
mh2 = mh.copy_and_clear()
mh.add_sequence('ATGC')
assert mh.similarity(mh2) == 0
assert mh2.similarity(mh) == 0
