This class inherits from both ValueError and AttributeError to help with exception handling and backward compatibility. Examples -------- >>> from sklearn.svm import LinearSVC >>> from sklearn.exceptions import NotFittedError >>> try: ... LinearSVC().predict([[1, 2], [2, 3], [3, 4]]) ... except NotFittedError as e: ... print(repr(e)) NotFittedError("This LinearSVC instance is not fitted yet. Call 'fit' with appropriate arguments before using this estimator."...) .. versionchanged:: 0.18 Moved from sklearn.utils.validation. Nrrrrrrrr.srrceZdZdZdS)rzrCustom warning to capture convergence problems .. versionchanged:: 0.18 Moved from sklearn.utils. Nrr rrrrDrrceZdZdZdS)raWarning used to notify implicit data conversions happening in the code. This warning occurs when some input data needs to be converted or interpreted in a way that may not match the user's expectations. For example, this warning may occur when the user - passes an integer array to a function which expects float input and will convert the input - requests a non-copying operation, but a copy is required to meet the implementation's data-type expectations; - passes an input whose shape can be interpreted ambiguously. .. versionchanged:: 0.18 Moved from sklearn.utils.validation. Nrr rrrrLsrrceZdZdZdS)raCustom warning to notify potential issues with data dimensionality. For example, in random projection, this warning is raised when the number of components, which quantifies the dimensionality of the target projection space, is higher than the number of features, which quantifies the dimensionality of the original source space, to imply that the dimensionality of the problem will not be reduced. .. versionchanged:: 0.18 Moved from sklearn.utils. Nrr rrrr^s    rrceZdZdZdS)ra5Warning used to notify the user of inefficient computation. This warning notifies the user that the efficiency may not be optimal due to some reason which may be included as a part of the warning message. This may be subclassed into a more specific Warning class. .. versionadded:: 0.18 Nrr rrrrlsrrceZdZdZdS)raaWarning class used if there is an error while fitting the estimator. This Warning is used in meta estimators GridSearchCV and RandomizedSearchCV and the cross-validation helper function cross_val_score to warn when there is an error while fitting the estimator. .. versionchanged:: 0.18 Moved from sklearn.cross_validation. Nrr rrrrwrrceZdZdZdS)rzWarning class used to notify the user of a test that was skipped. For example, one of the estimator checks requires a pandas import. If the pandas package cannot be imported, the test will be skipped rather than register as a failure.

Nrr rrr r r"rr ceZdZdZdS)r aWarning raised when the eigenvalues of a PSD matrix have issues This warning is typically raised by ``_check_psd_eigenvalues`` when the eigenvalues of a positive semidefinite (PSD) matrix such as a gram matrix (kernel) present significant negative eigenvalues, or bad conditioning i.e. very small non-zero eigenvalues compared to the largest eigenvalue. .. versionadded:: 0.22 Nrr rrr r r'rr ceZdZdZdZdZdS)InconsistentVersionWarninga3Warning raised when an estimator is unpickled with a inconsistent version.
