stage 0.0 (TID 0) org.apache.spark.SparkException: Error from python worker: /usr/bin/python: can't decompress
在CentOS以及其他的Linux系统中遇到安装包安装错误的原因,大多数都是因为缺少依赖包导致的,所以对于错误:zipimport.ZipImportError: can’t decompress data
报错问题:Failed to import package with error: Couldn’t decompress package 今天在导入一个资源包的时候突然提示报错:Failed to import...package with error: Couldn’t decompress package 遇到这种错误有两种可能 1.
