我正在尝试使用 python 在 windows 10 中的 spark-nlp 中安装预训练管道。以下是我目前在本地系统的 Jupyter notebook 中尝试过的代码：
! java -version
# should be Java 8 (Oracle or OpenJDK)
! conda create -n sparknlp python=3.7 -y
! conda activate sparknlp
! pip install --user spark-nlp==2.6.4 pyspark==2.4.5
from sparknlp.base import *
from sparknlp.annotator import *
from sparknlp.pretrained import PretrainedPipeline
import sparknlp
# Start Spark Session with Spark NLP
# start() functions has two parameters: gpu and spark23
# sparknlp.start(gpu=True) will start the session with GPU support
# sparknlp.start(sparrk23=True) is when you have Apache Spark 2.3.x installed
spark = sparknlp.start()
# Download a pre-trained pipeline
pipeline = PretrainedPipeline('explain_document_ml', lang='en')
我收到以下错误：
explain_document_ml download started this may take some time.
Approx size to download 9.4 MB
[OK!]
