Describe the bug

In grid_to_graph, you expect the vertices to correspond to the implicit order defined by the mask. This is not always the case, due to the occurrence of isolated vertices that are dismissed in the reindexing of the vertices.

Steps/Code to Reproduce

import numpy as np
from sklearn.feature_extraction import grid_to_graph

mask = np.zeros((2, 3)).ast

What is the problem?

It seems that Ray doesn't allow using a class variable to keep track of some shared class-level information, such as how many instances of the class have been created.

I understand there are at least a couple of ways I can accomplish sharing state across instances:

  1. I can use a different class with an counter instance variable and have all of the launched clas

This is both a bug report /feature request:

Any optimizer.step function might have a return value. However, NO return values are currently handled by the optimizer.LightningOptimizer class in the "step" function. Optimizers with return values in their step function therefore do not operate properly.

BugFix: Add return value to to the respective line, something like:

return_val=None

The options "Include Schema" and "Include Contents" in the SQL exporter dialog can be a bit mysterious for users.

Proposed solution

Just like concrete SQL commands are included in the UI text elsewhere in the dialog ("DROP"), we could expand these phrases to mention the corresponding SQL commands ("CREATE TABLE", "INSERT").

Alternatives considered

We could also drop the mention

You can’t perform that action at this time.
