How can i save and load pretrained MIRNet pretrained save models?

i found this mirnet model for a while but so far the only way for me to find it working is either from keras tutorial or kaggle tutorial.

both of em are working but neither one of em give tutorial to save the model that has been trained/downloaded and its frustating. i tried many guides to save the model as h5, pth, tf and even directory but still not a single one of those method can be loaded.

pls help im hopeless. im still new and my python packages instalation are still janky.
