[jira] [Updated] (SPARK-33203) Pyspark ml tests failing with
rounding errors
[ https://issues.apache.org/jira/browse/SPARK-33203?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alessandro Patti updated SPARK-33203:
-------------------------------------
Description:
The tests _{{pyspark.ml.recommendation}}_ and _{{pyspark.ml.tests.test_algorithms}}_ occasionally fail (depends on environment) with
{code:java}
File "/home/jenkins/python/pyspark/ml/tests/test_algorithms.py", line 96, in test_raw_and_probability_prediction
self.assertTrue(np.allclose(result.rawPrediction, expected_rawPrediction, atol=1))
AssertionError: False is not true{code}
{code:java}
File "/home/jenkins/python/pyspark/ml/recommendation.py", line 256, in _main_.ALS
Failed example:
predictions[0]
Expected:
Row(user=0, item=2, newPrediction=0.6929101347923279)
Got:
Row(user=0, item=2, newPrediction=0.6929104924201965)
...{code}
