However, one exception to this is that the maximum dimension count for the Lucene engine is 1,024, compared with 16,000 for the other engines. ref LlamaIndex ElasticsearchReader class: The name of the class in LlamaIndex is ElasticsearchReader. However, actually, it can only work with open...
we are concerned with Python exceptions here. If you’ve ever seen a complete set of logs from a YARN-managed PySpark cluster, you know that a single ValueError can get logged tens of times in different forms; our goal will be to make sure all of them are either not present or encrypte...
We can use the expect_column_values_to_be_unique method to validate this. gdf.expect_column_values_to_be_unique(column = 'passengerid')#output{ "exception_info": { "raised_exception": false, "exception_traceback": null, "exception_message": null }, "result": { "element_count": 891...
