Jeremy Freeman commented on SPARK-9461: --------------------------------------- Ah, great to hear! > Possibly slightly flaky PySpark StreamingLinearRegressionWithTests > ------------------------------------------------------------------ > > Key: SPARK-9461 > URL: https://issues.apache.org/jira/browse/SPARK-9461 > Project: Spark > Issue Type: Bug > Components: MLlib, PySpark > Affects Versions: 1.5.0 > Reporter: Joseph K. Bradley > Assignee: Jeremy Freeman > > [~freeman-lab] > Check out this failure: > [https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/38913/consoleFull] > It should be deterministic, but do you think it's just slight variations > caused by the Python version? Or do you think it's something odd going on > with streaming? This is the only time I've seen this happen, but I'll post > again if I see it more. > Test failure message: > {code} > ====================================================================== > FAIL: test_parameter_accuracy (__main__.StreamingLinearRegressionWithTests) > Test that coefs are predicted accurately by fitting on toy data. > ---------------------------------------------------------------------- > Traceback (most recent call last): > File > "/home/jenkins/workspace/SparkPullRequestBuilder/python/pyspark/mllib/tests.py", > line 1282, in test_parameter_accuracy > slr.latestModel().weights.array, [10., 10.], 1) > File > "/home/jenkins/workspace/SparkPullRequestBuilder/python/pyspark/mllib/tests.py", > line 1257, in assertArrayAlmostEqual > self.assertAlmostEqual(i, j, dec) > AssertionError: 9.4243238731093655 != 9.3216175551722014 within 1 places > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
