Load weight from hdf5 file

I have a weight file whose format is hdf5. I want to load the weight parameters in hdf5 into my model.

How can i make it happen in pytorch?

Have a look at https://github.com/szagoruyko/functional-zoo/blob/master/resnet-18-export.ipynb
hickle is actually an interface for hdf5, so the example is actually loading a hdf5 file (but using the functional interface of pytorch, but the same thing can be done for models defined using nn.Module)

Could you please tell me how to load weights to hdf5 file.
I am quite new to this.
Thanks !

What if, reversely, I want to export a .h5 file out of an existing CNN constructed with pytorch?
Is there any trick for this please?
