My first choice is "spacy". spacy is better then all other python NLP. But Spacy is new NLP and It have not good support online. -- You received this message because you are subscribed to the Google Groups "sympy" group. To unsubscribe from this group and stop receiving emails from it, send

Re: [sympy] Adding is_empty property

Most matrix properties can be extended to empty matrices. You have to check the definitions carefully with vacuous truth in mind to see what they should be, though. On Tue, Mar 8, 2016 at 9:16 AM, Aravind Reddy wrote: > Sir, > > I found from issue 10701 that using is_nilpotent() function for chec

Re: [sympy] Re: simplify works on expression but not on its negative

Definitely a bug. A workaround is to use (-I/2*exp(I*theta) + I/2*exp(-I*theta)).rewrite(sin), which will force the exponentials to be rewritten in terms of sin and cos. Aaron Meurer On Mon, Mar 14, 2016 at 4:10 AM, Francesco Bonazzi wrote: > A related issue: > > In [6]: m = Matrix([[0, theta],

Re: [sympy] GSOC - Natural Input Parser

External dependencies are fine for SymPy Gamma, especially if it's something like an NLP framework, which we wouldn't want to rewrite ourselves. Aaron Meurer On Sun, Mar 13, 2016 at 9:45 PM, Jerry Li wrote: > Hi, > > I'm beginning to work on a proposal for this project, and I just had a > questi

[sympy] Re: Adding is_empty property

Thanks sir for you valuable input. I have closed the issue with addition of the property is_empty() as Moore pointed that it will be redundant. And now I agree on the point to return true for the nil potent matrix though it doesn't have an eigen value

Re: [sympy] Re: Adding is_empty property

Oh yeah, I forgot that "if A" will also be the same as "if A.is_empty". So it's not needed. Aaron Meurer On Mon, Mar 14, 2016 at 2:15 PM, Aravind wrote: > Thanks sir for you valuable input. I have closed the issue with addition of > the property is_empty() as Moore pointed that it will be redund
