Preserving the output cells in Jupyter notebooks that are checked in to
this repo bloat the repo size, and keeping the output is not necessary
because the notebooks are run as part of the CI for producing docs.
For example, in https://github.com/cleanlab/cleanlab/pull/165, the
`audio.ipynb` is 112K (and now part of the repo history forever), while
clearing the output cells reduces that size down to 24K. I suspect that
Git's delta compression will also work better without the output cells
there as we make changes to the notebook. Also, the diffs will be more
readable.
* Move _process_label_issues_kwargs to fit method
* Add test for sklearn GridSearchCV with kwargs
* Add comment to test for sklearn GridSearchCV with kwargs
* Change cv=3 for GridSearchCV in test
* improved language in docs Quickstart
* LearningWithNoisyLabels refactor to improve API flexibility and UX
* fix LearningWithNoisy rare label handling
* additional arg-checking unit tests
LearningWithNoisyLabels used `sklearn.utils.check_X_y` to enforce that
`X` was 2D, to be in line with what sklearn's standard estimators
expect. However, LearningWithNoisyLabels is dataset-agnostic: it doesn't
look at the data points themselves. If the underlying classifier
supports data in a different shape, there's no reason
LearningWithNoisyLabels should prohibit it. Users have requested that we
relax this unnecessary restriction [1] so LearningWithNoisyLabels will
more naturally support e.g. image datasets and CNN models.
Thanks to @kothari1997narayan for suggesting this change.

Inspired by [1] and similar examples. See also: the pull request that
switches from `copy.deepcopy` to `sklearn.base.clone` [2]. Even the
latter calls `sklearn.base.clone(..., safe=False)` on the values
returned by `get_params()`, so the user has to be sure that their model
is correctly clonable, otherwise they may get silently incorrect
behavior.

Arbitrary scikit-learn estimators are not safe to clone via
`copy.deepcopy()`, for example when they contain state that cannot be
pickled, such as a Keras model that contains a `_thread.RLock` [1]. The
correct way to clone an estimator is to use `sklearn.base.clone()` [2],
which constructs a new unfitted estimator with the same parameters as
the original by calling `get_params()` followed by creating a new object
of the class, passing the parameters to `__init__()`. This patch
switches from `copy.deepcopy` to `sklearn.base.clone`.
This patch also updates the MNIST PyTorch CNN example model to be
compatible with `sklearn.base.clone`. Writing a custom `get_params`
implementation usually wouldn't be necessary with a more standard
estimator that inherits from `BaseEstimator`, but it was necessary to
override the method in this case because of the nonstandard
implementation that supports multiple datasets and does data loading
within the estimator itself based on the `dataset` argument.

`np.long` was deprecated in NumPy 1.20, and this was making the test
output noisy with deprecation warnings. This patch replaces the type
with `np.int32` (the labels are 0--9).
