If the software requires ANTLR4, then installing ANTLR3 is likely the issue. You need to figure out how to install ANTLR4. Maybe ask on their mailing list. Jason moorepants.info +01 530-601-9791 On Thu, Mar 10, 2016 at 11:05 AM, Aman Deep wrote: > Hi, Developers, > >

I think that creating a formula input widget for Jupyter would be a solid project to work on for GSoC. That would open up a lot of possibilities. Jason moorepants.info +01 530-601-9791 On Wed, Mar 9, 2016 at 2:10 PM, Francesco Bonazzi wrote: > Jupyter notebooks use

Note that you can simply type "%matplotlib notebook" if you want interactive plots from matplotlib in the notebook. Bokeh and mpld3 also give this functionality. Jason moorepants.info +01 530-601-9791 On Wed, Mar 9, 2016 at 8:06 AM, Sartaj Singh wrote: > > I ran the

Re: [sympy] GSoC 2016 - Classical Mechanics: Efficient Equation of Motion Generation with Python

The two equation of motion ideas can be combined. The C++ is a bigger effort because we do not yet have an easy way to replace SymPy objects with C++ backed objects in a seamless way. The problem is the same, we'd like to speed up the EoM formulations and the linearizations. There may be a lot to

No one has really worked on that package significantly for a number of years. You are welcome to work on it if it interests you. But you will likely need to drive the ideas for future additions yourself. There are a number of bugs in the issue tracker that need to be fixed. If you write one of the

Re: [sympy] Re: GSOC 2016: Classical Mechanics: Efficient Equation of Motion Generation with C++

Nice work. Now you can investigate the core functions for speed. You should investigate whether SymPy supports all of these functions. I would read the symengine list to get an idea of how symengine will be used in SymPy. Jason moorepants.info +01 530-601-9791 On Mon, Mar 7, 2016 at 10:12 AM,

Re: [sympy] Re: memory error

SymPy uses a cache to store results of computations so that you don't have expend much computational effort when doing repetitions of computations. You can manually clear that cache if you want using the function you show. Jason moorepants.info +01 530-601-9791 On Wed, Mar 2, 2016 at 8:16 AM,
