Error in default code from default download

[EngrStudent]

Process:

1. Downloaded zip, extracted into a useful directory. --> OK
2. Opened README.md, started working through "Getting Started"
3. in terminal, in directory, ran "pip3 install -r requirements. txt" --> all requirements satisfied
4. ran "python -m AlphaZeroGUI.main" --> Got ERROR

Here is the text for that error:

Traceback (most recent call last):
  File "/home/<username>/anaconda3/lib/python3.8/runpy.py", line 194, in _run_module_as_main
    return _run_code(code, main_globals, None,
  File "/home/<username>/anaconda3/lib/python3.8/runpy.py", line 87, in _run_code
    exec(code, run_globals)
  File "/home/<username>/<useful_directory>/AlphaZeroGUI/main.py", line 2, in <module>
    from PySide2.QtWidgets import QApplication, QMessageBox, QInputDialog, QTableWidgetItem, QLineEdit
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

It looks like the requirements.txt may need something involving "Pyside2".

I spun up a conda environment and manually am going through the requirements.... and now I get a GUI interface!!
