我目前在pio训练和火花方面遇到问题。
要单独运行火花，我必须运行下一个命令spark-submit --driver-class-path spark-timeseries/python/sparkts/sparkts-0.4.0-SNAPSHOT-jar-with-dependencies.jar train.py
对于集成，我尝试做pio train -- --driver-class-path spark-timeseries/python/sparkts/sparkts-0.4.0-SNAPSHOT-jar-with-dependencies.jar train.py（单个--用于解析为spark-submit的单独参数），但是出现以下错误ImportError: No module named pypio.utils是pio使用的模块。
我尝试过的另一种选择是pio train -- --driver-class-path /PredictionIO-0.12.1/conf:/PredictionIO-0.12.1/vendors/hbase-1.2.6/conf:spark-timeseries/python/sparkts/sparkts-0.4.0-SNAPSHOT-jar-with-dependencies.jar train.py，但是我遇到了同样的错误。
我认为我手动给出的--driver-class-path参数掩盖了pio的某些依赖性。
有人有主意吗？
PS。仅运行pio train时，这是完整的提交命令：
