AttributeError:LooseVersion实例没有属性“version”

我正在开发一个python程序,该程序读取拼花类型的文件并将其转换为熊猫数据帧。当我使用python命令运行它时,它工作得很好(python framework1.py arg1 arg2)。但在使用pyinstaller将其转换为可执行文件并运行该可执行文件后,会出现以下错误。

Traceback (most recent call last):
  File "framework1.py", line 325, in <module>
  File "filetype.py", line 24, in fileTypeSelector
  File "pandas/io/parquet.py", line 256, in read_parquet

AttributeError: LooseVersion instance has no attribute 'version'

提前感谢:)
