Exception Reference¶

Exception types raised by openseespy-solvers.

OpenSeesSolverError ¶

Bases: Exception

Base class for all openseespy-solvers exceptions.

UnsupportedStorageSchemeError ¶

Bases: OpenSeesSolverError, NotImplementedError

Sparse storage scheme is not supported.

Raised when storage_scheme is not 'CSR' or 'CSC'.

SolverConvergenceError ¶

Bases: OpenSeesSolverError

Iterative or eigen solver failed to converge.

InvalidOpenSeesDataError ¶

Bases: OpenSeesSolverError, ValueError

OpenSees passed missing or malformed buffer arguments.

UnsupportedComputeDtypeError ¶

Bases: OpenSeesSolverError, ValueError

Requested compute dtype is not supported (only float32 and float64).

BackendNotAvailableError ¶

Bases: OpenSeesSolverError, ImportError

Optional backend library is not installed.

For example, importing :mod:openseespy_solvers.cupy without cupy raises this exception. Install the CUDA 13 extra, for example python -m pip install "openseespy-solvers[cuda13]".
