"The system cannot find the file specified" during pgm.figure.savefig()

See original GitHub issue

I just installed daft (pip install daft) on my Windows machine but the last step of all of the samples is failing while trying to save the file.

Source Code (from sample):

from matplotlib import rc
rc("font", family="serif", size=12)
rc("text", usetex=True)

import daft

pgm = daft.PGM([3.6, 1.8], origin=[2.2, 1.6], aspect=2.1)
pgm.add_node(daft.Node("confused", r"confused", 3.0, 3.0))
pgm.add_node(daft.Node("ugly", r"ugly font", 3.0, 2.0, observed=True))
pgm.add_node(daft.Node("bad", r"bad talk", 5.0, 2.0, observed=True))
pgm.add_edge("confused", "ugly")
pgm.add_edge("ugly", "bad")
pgm.add_edge("confused", "bad")
pgm.render()
pgm.figure.savefig("badfont.pdf")
pgm.figure.savefig("badfont.png", dpi=150)

Error message:

Hi there, I encountered the same issue and solved it by changing this line of code rc("text", usetex=True) into rc("text", usetex=False)

Matplotlib requires MiKTeX and GhostScript for rendering text with LaTeX.

Also add C:\Program Files\MiKTeX 2.9\miktex\bin\x64 to your path.
