无法下载spark-nlp库提供的管道

Question

我无法使用spark-nlp库提供的预定义管道“ recognize_entities_dl”

我尝试安装不同版本的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.

     92         self.light_model = LightPipeline(self.model)

     50     def downloadPipeline(name, language, remote_loc=None):
     51         print(name + " download started this may take some time.")
---> 52         file_size = _internal._GetResourceSize(name, language, remote_loc).apply()
     53         if file_size == "-1":
     54             print("Can not find the model to download please check the name!")

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

感谢您确认您的Apache Spark版本。预先训练的管道和模型基于Apache Spark和Spark NLP版本。最低Apache Spark版本必须为2.4.x，才能下载经过预先​​训练的模型/管道。否则，您需要先针对任何版本训练自己的模型/管道。

这是所有管道的列表，它们全部用于Apache Spark 2.4.x：https://nlp.johnsnowlabs.com/docs/en/pipelines

如果您查看任何模型或管道的URL，您都可以看到以下信息：

recognize_entities_dl_en_2.1.0_2.4_1562946909722.zip

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

注意：正在根据Apache Spark 2.4.x构建和编译Spark NLP库。这就是为什么模型和管道仅适用于2.4.x版本的原因。

我希望这个答案能帮助您解决问题。
