Here I make this proof of concept public. Synthetic+Modelling. It will improve in time.
In your environment you need to install this:
pip install --upgrade https://github.com/Lasagne/Lasagne/archive/master.zip
pip install --upgrade numpy==1.20.3
pip install surpyval
and I made some modifications to the DeepSurv library, but the original should work fine in principle.
