pycvi.exceptions

PyCVI exceptions.

Exceptions

`EmptyClusterError`	The clustering algorithm didn't converge.
`InvalidKError`	The CVI was called with an incompatible number of clusters.
`InvalidScoreError`	The score given is not among the implemented scores.
`ScoreError`	The score given is invalid, probably because it is None.
`SelectionError`	The CVI couldn't select the best clustering.
`ShapeError`	The given data doesn't have the right shape.

exception pycvi.exceptions.EmptyClusterError

The clustering algorithm didn’t converge.

As a result of not converging, some clusters are empty resulting in the absence of clustering.

exception pycvi.exceptions.ShapeError

The given data doesn’t have the right shape.

The acceptable input shapes are: (N,) or (N, d) or (N, T, d).

exception pycvi.exceptions.InvalidScoreError

The score given is not among the implemented scores.

Either because its reduction was not implemented or because its main function was not implemented.

exception pycvi.exceptions.ScoreError: The score given is invalid, probably because it is None.

exception pycvi.exceptions.InvalidKError: The CVI was called with an incompatible number of clusters.

exception pycvi.exceptions.SelectionError

The CVI couldn’t select the best clustering.

This is probably because the CVI values given are all None or NaN or all equal.
