sympy/printing/tests/test_theanocode.py[27]
the error isHello @asmeurer @jksuom Sir I tried to debug the def _print_Symbol(self, expr):
and def _deal_with_super_sub(self, string):
methods in printing/latex.py file which could be the possible reasons of not enclosing symbol_latex
variable in {} which is causing the assertion error as I indicated in my sympy/sympy#15117 unfortnately I am not able to fix this error.Apart from it I tried to alter the value of variable Psi_symbol
to match the symbol_latex with indexed_latex but failed to do so.The following code is raising the assertion error
def test_latex_indexed():
Psi_symbol = Symbol('Psi_0', complex=True, real=False)
Psi_indexed = IndexedBase(Symbol('Psi', complex=True, real=False))
symbol_latex = latex(Psi_symbol * conjugate(Psi_symbol))
indexed_latex = latex(Psi_indexed[0] * conjugate(Psi_indexed[0]))
Please help me to fix this issue.
test_compilation.py
and test_pickling.py
. Also after the tests a new file is created called wrapper_module_20.pyx
. I am running sympy on a MAC OS X with Python 3.6.3. My local repo is in sync with the upstream master. Should I file an Issure regarding this or can someone please help me out here? I can provide more details regarding the error if necessary.
