org.apache.spark.SparkException: [FAILED_EXECUTE_UDF]

[Merlinish]

Hi all, I trained and saved the model according to this spark-nlp training, and then I tested it with some data. But I can't process the outcome of the model, It always shows the error:
when I tried to run the result.select("ner.result").show(truncate=False), it shows

org.apache.spark.SparkException: [FAILED_EXECUTE_UDF] Failed to execute user defined function (HasSimpleAnnotate$$Lambda$3933/0x00007f9ea1245468: (array<array<struct<annotatorType:string,begin:int,end:int,result:string,metadata:map<string,string>,embeddings:array>>>) => array<struct<annotatorType:string,begin:int,end:int,result:string,metadata:map<string,string>,embeddings:array>>).

and

Py4JJavaError: An error occurred while calling o388.showString.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 16.0 failed 1 times, most recent failure: Lost task 0.0 in stage 16.0 (TID 38) (172.19.230.207 executor driver): org.apache.spark.SparkException: [FAILED_EXECUTE_UDF] Failed to execute user defined function (HasSimpleAnnotate$$Lambda$3933/0x00007f9ea1245468: (array<array<struct<annotatorType:string,begin:int,end:int,result:string,metadata:map<string,string>,embeddings:array>>>) => array<struct<annotatorType:string,begin:int,end:int,result:string,metadata:map<string,string>,embeddings:array>>).

you can find my notebook screenshot here. the result format looks fine, but when you want to process it, the error shows.

Appreciate any help!

Hi @Merlinish

Could you please use NerDLApproach instead? It's much superior and not too sensitive to training dataset:

• https://github.com/JohnSnowLabs/spark-nlp/blob/master/examples/python/training/english/dl-ner/ner_bert.ipynb

all the other examples: https://github.com/JohnSnowLabs/spark-nlp/tree/master/examples/python/training/english/dl-ner

[maziyarpanahi]

PS: to also be sure this is not a bug, could you please copy the entire error from top to bottom and paste it here? (it's not possible to traverse inside the screenshot)

[Merlinish]

the entire error is here:
