New issue 4023 by [email protected]: solve provides the error:
sympy.polys.polyerrors.PolynomialError: only univariate polynomials are
allowed
http://code.google.com/p/sympy/issues/detail?id=4023
Hi every one,
I don't know whether this issue has been already addressed; therefore I
post this.
I have developed (in the past) a code using python 2.7.2 & sympy 0.7.1; the
code includes the call:
p2 =
np.array(sym.solve(fit_c2[8]+E*eps_yieldplast+(fit_c2[7]-E)*y+fit_c2[6]*y**2+fit_c2[5]*y**3+fit_c2[4]*y**4+fit_c2[3]*y**5+fit_c2[2]*y**6+fit_c2[1]*y**7+fit_c2[0]*y**8,y))
where I exploit the sympy's package solve. This line simply identify the
intercept between a line and a 8th order polynom. Everything works smoothly
and without problem.
Then right now I'm using pyhton 2.7.3 and sympy 0.7.3 and suddenly I get
the following error:
sympy.polys.polyerrors.PolynomialError: only univariate polynomials are
allowed. If I run this code on my laptop, which has still python 2.7.2 &
sympy 0.7.1 installed, I don't have any problem and everything run smoothly.
So is this bug known? There is a patch for it?
Thanks in advance for your support.
Luca
