# 🚀 Feature Request
I would like to be able:
- to persist my study in order to resume my hyperparameter search from where I left it
- set the `gc_after_trial` parameter of Optuna's `study.optimiz…

I was wondering if there was a way to batch the inputs when using Optuna or reduce the load on it.
Optuna seems to go out of memory and crash on google colab when I try to run it on my big dataset…
-
### Motivation
The Optuna's unit tests raise many warnings, which make it hard to recognize unexpected warning messages.
### Description
We can filter expected warnings using `@pytest.mark.filterwa…

Hi !
I am confused how to define a conditional search space with the optuna plugin.
For instance, I want to use the hydra-optuna to search which optimizer is better from [SGD, Adam]. Meanwhile, …

# 🚀 Feature Request
Provide flags in Hydra config, that allow user to make Optuna sweeps fault tolerant.
## Motivation
When doing hyperparameter search, some of the jobs might crash unexpec…
-
### Motivation
In `plot_optimization_history`, showing some indicators of the optimization trend might be useful to understand if convergence occurs.
### Description
A possible solution is to…

Hi!
I want to search the best optimizer for the given "mnist_example" from SGD and Adam.
However, for SGD, I also want to know which momentum value is the best (which Adam doesn't need), but for …

Currently `optuna_dashboard` are using both `Grid` and `Unstable_Grid2`. Let's integrate them if possible.
**Unstable_Grid2**

## Proposal Summary
Make the optuna pruning experiment an informative message
## Motivation
While executing the hyper-parameter task with the optimizer set to Optuna, it would be terminating experi…

### Bug description
When Optuna is run in parallel mode (`n_jobs=-1`), with `NeptuneCallback`, I get:
`[neptune] [error ] Error occurred during asynchronous operation processing: X-coordinates (ste…
