hyperparameter_search.py script giving error: TypeError: 'NoneType' object is not callable

[quzhouxiachuan]

I slightly modified the hyperparameter search script so it can be used without using docker. I tried to run random search with different optimizers. My script works fine when using Adam as update_fn.

However, when using adadelta, it shows the following error:
OMP_NUM_THREADS=10 python hyperparam_search_test.py ./ /home/ydw529/DEEPLEARNING/code/deepsur_dneg/DeepSurv/hyperparam_search/box_constraints.0.json 50 --num_epochs 500 --update_fn "adadelta"

File "/home/ydw529/.conda/envs/theano/lib/python3.8/site-packages/deepsurv/deep_surv.py", line 211, in _get_loss_updates updates = update_fn( TypeError: 'NoneType' object is not callable

I am wondering if anyone had the same issue before? If so, how did you solve it? Much appreciated!

Are you still facing the issue?

This is because the 'adadelta' updater isn't implemented in the utils function: here. So the function is returning "None".

If you can update the utils function with the correct code and send a PR, I would be happy to merge it!
