导入pyside2出现如下问题
ImportError: /usr/lib/x86_64-linux-gnu/libgssapi_krb5.so.2: symbol krb5_ser_context_init version krb5_3_MIT not defined in file libkrb5.so.3 with link time reference
这是由于anaconda或机器中qt版本不对
参考 stackoverflow上解答

  pip uninstall pyside2, qt, pyqt5 if you have installed them with pip
  conda remove pyside2, qt, pyqt5 if you have installed them with conda
 conda install -c conda-forge pyside2
这里最后一步一直失败改装了老版本
 
pip install pyside2==5.13.0
