[Also in the object method `d` and `x`](https://github.com/andgoldschmidt/derivative/blob/7aa93ce4e3d92a335b8d156239f5ffa6cf654322/derivative/differentiation.py#L177) FWIW in pysindy we explicitly [set the axis](https://github.com/dynamicslab/pysindy/blob/cbb68638704cda26c3db4c05106b448778c324f7/pysindy/differentiation/sindy_derivative.py#L80) when calling `derivative`, so we don't have to worry about whether changing the default...

#41 added `_align_axes` to allow differentiating data that was greater than 2D. Looks like I omitted to add a docstring to that function, but it orients the desired axis as...

> how that works mathematically Alternative view: what we consider an n-dimensional numpy array is really a contiguous list of memory locations along with information what size strides to take...

Hmm, this is curious. `keepdims` defaults to `_NoValue`, not `None` or `False`, even though the default behavior is `False`. Thus the static typing sees the failing test as overload 2...

Thanks @chaitanya94! @NolanBrb, can you report your numpy version?

Thanks for your suggestion! We'd love anything that speeds up SINDy. I've got a few clarification questions > The lack of a way to extract the dynamics as an evaluable...

Leaving some troubleshooting here in case I don't finish this now. ~At first blush, this looks to be a statefulness/mutability issue, and that `prob` is modified inside the `try` statement...

There is no guarantee that generic SINDy discovers stable models. Look into `TrappingSINDy`. Also, for these "how do I get better results from this problem" questions, it helps to have...

Ohhh, I think I'm looking for `model.optimizer.coef_full_`, which is `-1e-8` in this example? I think there may be an issue with the docstring mixing up its variables: > Attempts to...

Hey JR, thanks for your question! Using pysindy to get an explainable counterpart to a NN is a cool use case! I am not super familiar with closure models, so...
