I remember you that the last release don't handle LaTeX. So Sympy does not understand it and raise a ValueError. The module catch them now (in a unreleased version) and... ignore them because this kind of error happens when the user write anything with a syntax error or when the module try to eval whereas the entry is not a math formula or... So, there will always be this kind of error. Each time no parser work and the entry is directly sent to Sympy and fail.

Moreover, I hope you know your formula has no meaning: ! File ended while scanning use of \frac . Le 20/01/2015 10:18, Valentin Lorentz a écrit :
