From 844328059ef44baba689f5335219dd69b22bb0df Mon Sep 17 00:00:00 2001 From: Sagar Dollin Date: Sun, 29 Aug 2021 01:42:01 +0530 Subject: [PATCH 1/6] Updated RandomState (deprecated from numpy) to default_rng (Generator) This is regarding the issue #2782 . Here are the benchmarks of before and after updating: Before Update After Update Poincare Ran 42 tests in 0.418s Ran 42 tests in 0.417s test_lda Ran 48 tests in 223.845s Ran 48 tests in 225.561s utils Ran 24 tests in 0.007s Ran 24 tests in 0.007s test_matutils Ran 18 tests in 0.071s Ran 18 tests in 0.070s word2vec Ran 79 tests in 58.149s Ran 79 tests in 57.950s I don't find a big difference in time taken. However I feel it is good to be updated along with numpy. --- gensim/models/ldamodel.py | 2 +- gensim/models/poincare.py | 7 +++++-- gensim/models/test_poincare.py | 14 ++++++++++++++ gensim/models/word2vec.py | 2 +- gensim/models/word2vec_inner.pyx | 21 ++++++++++++++++----- gensim/test/test_ldamodel.py | 8 ++++---- gensim/test/test_matutils.py | 2 +- gensim/utils.py | 6 +++--- 8 files changed, 45 insertions(+), 17 deletions(-) create mode 100644 gensim/models/test_poincare.py diff --git a/gensim/models/ldamodel.py b/gensim/models/ldamodel.py index 6691ddcc31..ad58efec3c 100755 --- a/gensim/models/ldamodel.py +++ b/gensim/models/ldamodel.py @@ -1174,7 +1174,7 @@ def show_topics(self, num_topics=10, num_words=10, log=False, formatted=True): num_topics = min(num_topics, self.num_topics) # add a little random jitter, to randomize results around the same alpha -

Example in test_similarity_mertics , I added a delta of 5.0e-06 to incorporate small changes. Note in test_ensemblelda i had to remove 2 tests as these two test were comparing previously saved model with new model , which will be not same as we are using different Random Generator.
