About vsrl_eval.py and an error occurred during the test.

[YSN1011]

Dear Authors,

Thank you very much for releasing the code (https://github.com/SiyuanQi/gpnn) of your GPNN for HOI work. I'd like to ask you some questions.
1.The vsrl_eval.py file is under the VCOCO data set. Should I put it in the same directory as the VCOCO. Py file?If not, I will display an impot error.
2.When I test, the following error will be shown.KeyError: u'stand_agent'. Is it because the PKL file generated by my training is not correct?

Have you solved the third question?
I meet the same problem.
