Issue with Plot function

[Kundan Kumar]

I am trying to use Plot function of sympy but it is giving error displaying "ImportError: pyglet is required for plotting"

I googled the problem and the suggestion was to change a "except to except Importerror" but its already Importerror.

But still its not working. Any suggestion why its not working.

You first need to install pyglet by running  $ sudo apt-get install python-pyglet

The new plotting module uses matplotlib. You can have a look at the documentation

at http://docs.sympy.org/dev/modules/plotting.html#plotting-function-reference.

Thanks Sahil, it worked.

But did sympy not contain pyglet implicitly.

[Kundan Kumar]

Thanks Bharath,

Do I have to install matplotlib library explicitly.

[SAHIL SHEKHAWAT]

yes! indeed you have to install the necessary libraries for the sympy dependencies. Sympy does not contain these libraries on its own, Sympy is itself a library.

SymPy used to ship a copy of pyglet, but we stopped doing it, since it
can be installed separately, and the pyglet plotting is not the best
plotting anyway (you should prefer the new plotting module with
plot(), rather than Plot()).
