<div>Hi,<br>

I am trying to initialize a LCL TAO solver with petsc4py:<br>

<br>

<blockquote>from petsc4py import PETSc<br>

solver = PETSc.TAO().create()<br>

solver.setType(PETSc.TAO.Type.LCL)<br>

</blockquote>

<br>

The last line throws the following error:<br>

<br>

<blockquote>Traceback (most recent call last):<br>

  File "<string>", line 3, in <module><br>

  File "petsc4py/PETSc/TAO.pyx", line 183, in petsc4py.PETSc.TAO.setType<br>

petsc4py.PETSc.Error: error code 86<br>

[0] TaoSetType() at /petsc/src/tao/interface/taosolver.c:2164<br>

[0] Unable to find requested Tao type lcl<br>

</blockquote>

<br>

However, hasattr(solver.Type(), 'LCL') returns True. The same happens with any other

<span>PETSc.TAO.Type</span>. What am I missing here?<br>

<br>

Cheers,<br>
