目前，我正在尝试使用Python的Pixiedust包从笔记本中存储数据到Cloudant DB中。在建立连接后，当试图向数据库插入数据时，它给了我这个错误。
nPy4JJavaError: An error occurred while calling o172.save.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 3 in stage 38.0 failed 10 times, most recent failure: '
Lost task 3.9 in stage 38.0 (TID 1811, yp-spark-dal09-env5-0046): spray.http.IllegalUriException: The path of an URI without authority must not begin with "//"
请告诉我如何从笔记本中存储数据到Cloudant DB ?
此问题已得到解决，新版本的PixieDust已上传到PyPI。您可以通过发出以下命令在笔记本中下载最新版本:
!pip install --user --upgrade --no-deps pixiedust
升级完成后重启内核。
您可以通过运行以下命令来验证PixieDust版本(这在0.40版本中已修复):
!pip show pixiedust
输出应该类似于以下内容:
