python - spark-nlp 'JavaPackage' object is not callable

Question

I am using jupyter lab to run spark-nlp text analysis. At the moment I am just running the sample code:

import sparknlp
from pyspark.sql import SparkSession
from sparknlp.pretrained import PretrainedPipeline
#create or get Spark Session
#spark = sparknlp.start()
spark = SparkSession.builder 
    .appName("ner")
    .master("local[4]")
    .config("spark.driver.memory","8G")
    .config("spark.driver.maxResultSize", "2G") 
    .config("spark.jars.packages", "com.johnsnowlabs.nlp:spark-nlp_2.11:2.6.5")
    .config("spark.kryoserializer.buffer.max", "500m")
    .getOrCreate()
print("sparknlp version", sparknlp.version(), "sparkversion", spark.version)

#download, load, and annotate a text by pre-trained pipeline
pipeline = PretrainedPipeline('recognize_entities_dl', 'en')
result = pipeline.annotate('Harry Potter is a great movie')

I get the following error:

---------------------------------------------------------------------------

TypeError: 'JavaPackage' object is not callable

I read a few of the github issues developers raised in spark-nlp repo, but the fixes are not working for me. I am wondering if the use of pyenv is causing problems, but it works for everything else. My jupyter lab is launched like so: /home/myuser/.pyenv/shims/jupyter lab --no-browser --allow-root --notebook-dir /home/myuser/workdir/notebooks

My env configuration:

ubuntu: 20.10 Apache Spark: 3.0.1 pyspark: 2.4.4 spark-nlp: 2.6.5 pyenv: 1.2.21

Java:

openjdk 11.0.9 2020-10-20
OpenJDK Runtime Environment (build 11.0.9+10-post-Ubuntu-0ubuntu1)
OpenJDK 64-Bit Server VM (build 11.0.9+10-post-Ubuntu-0ubuntu1, mixed mode, sharing)

jupyter:

jupyter core     : 4.7.0
jupyter-notebook : 6.1.5
qtconsole        : 5.0.1
ipython          : 7.19.0
ipykernel        : 5.4.2
jupyter client   : 6.1.7
jupyter lab      : 2.2.9
nbconvert        : 6.0.7
ipywidgets       : 7.5.1
nbformat         : 5.0.8
traitlets        : 5.0.5

I appreciate your help .. thank you

Remove Spark 3.0.1, leave just PySpark 2.4.x. as Spark NLP still doesn't support Spark 3.x. Use Java 8 instead of Java 11 because it's not supported in Spark 2.4.
