Ipython daft matplotlib latex deficiency

Question

I really wanted to try daft ( http://daft-pgm.org/ ), and thanks to this, I found out that latex functionality does not work in matplotlib.

Paste this example into the daft website ( http://daft-pgm.org/examples/nocircles/ ):

from matplotlib import rc rc("font", family="serif", size=12) rc("text", usetex=True) import daft pgm = daft.PGM([3.6, 2.4], origin = [1.15, 0.8], node_ec="none") pgm.add_node(daft.Node("cloudy", r"cloudy", 3, 3)) pgm.add_node(daft.Node("rain", r"rain", 2, 2)) pgm.add_node(daft.Node("sprinkler", r"sprinkler", 4, 2)) pgm.add_node(daft.Node("wet", r"grass wet", 3, 1)) pgm.add_edge("cloudy", "rain") pgm.add_edge("cloudy", "sprinkler") pgm.add_edge("rain", "wet") pgm.add_edge("sprinkler", "wet") pgm.render() pgm.figure.savefig("nocircles.pdf") pgm.figure.savefig("nocircles.png", dpi=150) 

This is what ipython returns to me

 RuntimeError: LaTeX was not able to process the following string: 'lp' Here is the full report generated by LaTeX: 

There is no report provided by ipython or LaTex. See screenshot:

The standard script on matplotlib gives me the same error. Is there a way to check if all dependencies are satisfied? LaTex is installed on my system, but I'm not sure if ipython can access it.

Answer 1

In my case, it was the LaTex library that was supposed to be installed (sorry, I did not pay attention to which one)

It automatically opened my MikTex installer, so you install the proposed library and you have to do it.

It is not necessary that 'lp' be accessible from the command line.
