无法下载sparknlp库提供的管道

Question

我无法使用spark nlp库提供的预定义管道“识别\u实体\u dl”

我试着安装不同版本的pyspark和spark nlp库

import sparknlp
from sparknlp.pretrained import PretrainedPipeline

#create or get Spark Session

spark = sparknlp.start()

sparknlp.version()
spark.version

#download, load, and annotate a text by pre-trained pipeline

pipeline = PretrainedPipeline('recognize_entities_dl', lang='en')
result = pipeline.annotate('Harry Potter is a great movie')

2.1.0
recognize_entities_dl download started this may take some time.

AttributeError: module 'sparknlp.internal' has no attribute '_GetResourceSize'

感谢您确认您的apachespark版本。预先训练的管道和模型基于apachespark和Spark NLP版本。最低的apachespark版本必须是2.4.x，才能下载预先训练好的模型/管道。否则，您需要为任何版本培训自己的模型/管道。你知道吗

这是Apache Spark 2.4.x的所有管道和它们的列表： https://nlp.johnsnowlabs.com/docs/en/pipelines

如果您查看任何模型或管道的URL，可以看到以下信息：

recognize_entities_dl_en_2.1.0_2.4_1562946909722.zip

• 名称：recognize_entities_dl
• 朗：en
• 火花NLP：必须等于2.1.0或更大
• Apache Spark：等于2.4.x或更大

注意：Spark NLP库是根据apachespark2.4.x构建和编译的。这就是为什么模型和管道只能用于2.4.x版本。你知道吗

注意2：因为您使用的是Windows，所以需要使用与Windows兼容的_noncontrib模型和管道：Do Spark-NLP pretrained pipelines only work on linux systems?

我希望这个答案能帮助你解决问题。你知道吗
