加载PipelineModel加载函数故障排除时出错

标签: python apache-spark pyspark pipeline

我正在尝试使用PipelineModel.load()函数加载逻辑回归模型,该模型在2周前运行良好,但最近显示了错误。我的应用程序经过了docker化处理,没有任何更改,但是最近它即使在以前已成功执行的旧输入文件中也停止了工作。 在单独运行代码时,我遇到了以下错误,这些错误我已完全粘贴。

最近有人遇到类似的错误吗?任何见解都会有所帮助。

model1 = PipelineModel.load(PicklePath)


model1 = PipelineModel.load(PicklePath)
