安装sparknlp后，无法导入sparknlp

以下内容在 Cloudera CDSW 集群网关上成功运行。

import pyspark
from pyspark.sql import SparkSession
spark = (SparkSession
            .builder
            .config("spark.jars.packages","JohnSnowLabs:spark-nlp:1.2.3")
            .getOrCreate()
         )

从而产生这个输出。

但是当我尝试导入sparknlp时，如上所述约翰·斯诺实验室 http://nlp.johnsnowlabs.com/components.html对于 pyspark...

import sparknlp
# or 
from sparknlp.annotator import *

我明白了：

ImportError: No module named sparknlp
ImportError: No module named sparknlp.annotator 

我需要做什么才能使用sparknlp？当然，这可以推广到任何 Spark 包。

您可以使用以下命令在 PySpark 中使用 SparkNLP 包：

pyspark --packages JohnSnowLabs:spark-nlp:1.3.0

但这并没有告诉 Python 在哪里可以找到绑定。按照类似报告的说明进行操作here https://issues.apache.org/jira/browse/SPARK-21186，可以通过将 jar 目录添加到 PYTHONPATH 来修复此问题：

export PYTHONPATH="~/.ivy2/jars/JohnSnowLabs_spark-nlp-1.3.0.jar:$PYTHONPATH"

or by

import sys, glob, os
sys.path.extend(glob.glob(os.path.join(os.path.expanduser("~"), ".ivy2/jars/*.jar")))
