How to model inference

[home56200]

Hello author :
(1) Is your inference model in [Google Colab] ImageNET?
I tried to copy the [Google Colab] code to execute it, but the following error occurred, how can I solve it?

(2) What is the inference method of the models of other training sets such as: COCO 2017 data set and Pascal VOC? You did not mention this part in the code?

Thank you very much
