我正在使用jupyter实验室运行spark-nlp文本分析。目前我正在运行示例代码：
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')
我得到以下错误：
---------------------------------------------------------------------------

我读到了开发人员在spark-nlp-repo中提出的一些github问题，但修复程序对我不起作用。我想知道pyenv的使用是否会造成问题，但它对其他一切都有效。我的jupyter实验室是这样启动的：/home/myuser/.pyenv/shims/jupyter lab --no-browser --allow-root --notebook-dir /home/myuser/workdir/notebooks
我的env配置：
ubuntu:20.10Apache Spark:3.0.1pyspark:2.4.4火花nlp:2.6.5pyenv: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

我感谢你的帮助。。谢谢
删除Spark 3.0.1，只保留PySpark 2.4.x，因为Spark NLP仍然不支持Spark 3.x。使用Java 8而不是Java 11，因为它在Spark 2.4中不受支持。
