Test Trained model on I3d Resnet

I am pretty new to Action Recognition and I was able to train a model with transfer learning following the example on MxNet tutorials( 7. Fine-tuning SOTA video models on your own dataset- 7. Fine-tuning SOTA video models on your own dataset — gluoncv 0.10.0 documentation)
I used the python script inference.py to test but this only works with the pre-trained models in the Mxnet model zoo.
I will be glad to receive any information on how to test the model or any repo that could be of help.
