can someone help me with this? I have tried every suggestions from sympy community but still the error persist in the doc string. I have updated sympy : !pip install sympy --upgrade to sympy 1.7.1 I am using latest python 3.9.1.
I have gone through the documentation and found this : *sympy.assumptions.refine.refine(expr, assumptions=True)* *Simplify an expression using assumptions.* *Gives the form of expr that would be obtained if symbols in it were replaced by explicit numerical expressions satisfying the assumptions.* Since it , return an *expression *based on the assumptions provided it means : *refine(Q.real(x) , Q.positive(x))* must be an expression not a *True boolean* value If I understand it falsely then please help me , your help and suggestions will be highly appreciated.
