Convert Magika to NNEF

[george-hopkins]

I'd like to convert the Magika model to NNEF but the process seems to fail to some reason. I suspect it might be related to the input shape. Is it possible to use tract with this model?

$ tract magika/python/magika/models/standard_v1/model.onnx -i 1,1536,f32 dump --nnef magika.nnef.tgz
