Comment (by mstreng):
I know why the warning is printed twice: the line that caused the warning
is printed, after the warning is printed. You can specify how deep in the
stack this line needs to be found:
Without specifying stacklevel or when giving stacklevel=1:
{{{
/Users/marcostreng/sage-5.9.beta1/local/lib/python2.7/site-
packages/sage/rings/number_field/number_field_rel.py:310: UserWarning:
PARI only handles integral absolute polynomials. Computations in this
field might trigger PARI errors
warn("PARI only handles integral absolute polynomials. Computations in
this field might trigger PARI errors", stacklevel=1)
}}}
stacklevel=2:
{{{
/Users/marcostreng/sage-5.9.beta1/local/lib/python2.7/site-
packages/sage/rings/number_field/number_field.py:4116: UserWarning: PARI
only handles integral absolute polynomials. Computations in this field
might trigger PARI errors
return NumberField_relative(self, poly, str(name), check=check,
embedding=embedding)
}}}
stacklevel=3:
{{{
/Users/marcostreng/sage-5.9.beta1/local/bin/sage-ipython:1: UserWarning:
PARI only handles integral absolute polynomials. Computations in this
field might trigger PARI errors
#!/usr/bin/env python
}}}
Anyway, no value of stacklevel seemed to provide me with anything useful
for .py or .sage files or the IPython console, so we might as well keep it
as it is.
